With so many dangers associated with smoking, especially the correlation between smoking and the development of lung cancer, it is amazing to see how many people continue to voluntarily take part in this activity! Why is it that these mostly mature, reasonably intelligent men and women of every nationality allow such a small object to have so much control over their lives? You’d think it would be easy to just say “NO” to this tiny little death machine, but in reality it just isn’t so.
Why? Because smoking is a habit and habits are hard to break. Interestingly even efforts to raise the price of a pack of cigarettes have failed to slow the demand. And even though they aren’t cheap, cigarettes are very easy to buy, which makes it even harder to break this habit.
Smoking is the number one contributor to lung cancer. Besides causing lung cancer, cigarette smoking can cause other health-related problems including emphysema, bronchitis, and heart disease. Combine cigarette smoking with excess weight, stress, and a sedentary lifestyle, and a person who smokes literally becomes a ticking time bomb.
Here are some interesting bits of information about smoking and lung cancer.
Any amount of smoking can ultimately cause lung cancer, but how long you have been smoking, how deeply you inhale, and how many cigarettes you smoke on a regular basis all impact the development of lung cancer. It goes without saying that people who smoke a pack or more a day and who have smoked most of their lives are significantly increasing the likelihood that lung cancer will develop.
Quitting smoking may not stop lung cancer from developing, but doing so still is highly advisable. You immediately lower your risk of developing lung cancer the moment you stop (but only when you stop for good). The body will go into repair mode within a day or two after you stop. It’s not possible to determine whether the damage that has been done internally can be corrected, but stopping is worth the gamble.
Women are just as much at risk of developing lung cancer from smoking as men are, assuming equivalent smoking patterns and history. When it comes to lung cancer, men generally get most of the attention. There are more cases of men with smoking-related lung cancer than there are women, but don’t let this statistic fool you. Women are in danger too. In fact, more women die each year from smoking-related lung cancer than from breast cancer.
Passive smoking can also cause lung cancer, even in people who do not smoke. Passive smoking is the same as inhaling second-hand smoke. If you smoke, be considerate to others who don’t. Don’t smoke in enclosed spaces such as homes or cars. This is especially important around small children who don’t even realize the dangers they’re being exposed to.
If a pregnant woman smokes, her unborn baby smokes too!
And finally smoking is the cause of 90% of the cases of lung cancer. That alone should keep you from starting!

Lung cancer is one of the most common forms of cancer. If you have been diagnosed with lung cancer, the next thing you should do is to discuss with your doctors the most suitable lung cancer treatment for you. There are various options available for the treatment of lung cancer, but you will need to discuss these options carefully with your doctors and family before making a decision on the treatment method. Please bear in mind that the earlier the cancer is treated, the better will be your prognosis from this deadly disease.

Surgery is obviously one of the more effective treatment for removing the cancer from the body, however it all depends on how far along the cancer is. CT and PET scans are used to determine is the cancer can be removed through surgery, or if it is too far along and has spread to other areas making it harder to perform surgery. Blood tests and spirometry or lung function testing are also used to see if the patient can be operated on. Surgical procedures include wedge resction or partial removal of the lobe, a lobectomy or removal of one lobe, a bilobectomy or removal of two lobes, and pneumonectomy or the removal of an entire lung. A lobectomy is the most common form of surgery because it reduces the chance of the cancer returning.

Chemotherapy is also used to reduce the risk of the cancer recurring. The kind of chemotherapy used depends on the type of cancer and where it is located in the lungs. Radiotherapy is often used along with chemotherapy. 

Another form of lung cancer treatment besides these two is targeted therapy. Gefitinib is one such drug that targets the tyrosine kinase domain of the epidermal growth factor receptor. This has shown to increase the chances of survival in many of the people whom have taken this drug. Erlotinib is another drug that has been shown to increase the survival rate in cancer patients. Both of these drugs have been shown to be very effective in females, Asians and non-smokers.

Becoming diagnosed with lung cancer is a very serious thing to be told. There are several ways the cancer can be treated now but it is important to know all the lung cancer treatment options that are available to you. It is best to get surgery if at all possible, but if the cancer has spread into other areas, surgery is out of the question. Then chemotherapy, radiotherapy and targeted therapy can be considered. You should also explore the possibility of using other alternative cancer treatments. However, it is important for you to speak with your doctor the instance you have gotten lung cancer.

The effects of lung cancer on the patient’s body can differ according to the type and stage of the disease. However, studies are now focused towards the impact of treatments intended to cure the disease in patients. Although these have been recognized as temporary effects only, it still does produce enough good to the health of the patients. What Are The Effects of Lung Cancer Treatments?Since the treatment for the disease is essential to keep the cancer cells under control, several patients have overlooked the possible harm it can bring to their health. These are some of the more common treatment options for lung cancer.1) Surgical Treatment Effects of lung cancer treatment such as surgeries can often bring in more harm to the patient. Since it is a major operation, it exposes your chest area into the possibility of collecting air and fluid into it. Among the side effects known for lung cancer patients who have recently undergone surgery is difficulty in turning over, deep breathing, or even coughing. Since patients typically go through these activities, recovery might be slow. Activities such as deep breathing or coughing are essential elements in recovery since they enable extra air or fluid out of your lung area. Among the most common conditions cited shortly after undergoing lung cancer surgery include pain in your chest area or arms, and shortness of breath. It might need a week or two before a patient can find relief from such side effects. 2) ChemotherapyWhen it comes to the side effects produced by this type of treatment for lung cancer, it varies according to the type and amount of drugs given the patient. The hazard comes in since chemotherapy does not solely target cancer cells, but also affect normal cells as well. Below are common side effects experienced by patients treated with chemotherapy:•    vomiting/nausea•    feeling of fatigue•    presence of mouth sores•    hair loss3) Radiation TherapyThe effects of lung cancer treatments such as radiation therapy stems from the fact that, like chemotherapy, it affects your normal cells. As opposed to the type of drug used in chemotherapy, this one depends on the particular part of the body being treated and the amount of dosage. Common side effects include the following: sore or dry throat, hard time swallowing, changes in the skin of the area of treatment, appetite loss, headaches, problems with memory retention, etc. 4) Photodynamic TherapyThis particular therapy sets its limits on the normal routine activities of a patient who has undergone this treatment. For six weeks or more proceeding the treatment, the patient’s skin and eyes becomes hypersensitive to light. Therefore, direct contact with sunlight must be avoided if possible, even indoors. Hence, protective clothing must be worn if the patient were to go outside. Other entailing conditions of photodynamic therapy include difficulty swallowing, coughing, shortness of breath, or difficulty breathing. Although the conditions cited above are often considered temporary, they must not be taken lightly. Instead, you need to see your doctor if you notice some of the side effects of lung cancer treatments continue to persist.

Early detection of lung cancer warning signs – or any other types of illnesses – is crucial in helping to find a cure for the disease. Indeed, the earlier one is able to find out about the disease, the better chances they have for combating the illness. Lung cancer warning signs are similar to recognizing the symptoms of the disease. Hence, having enough knowledge of other conditions associated with this illness would be helpful. Below is a list of lung cancer warning signs you should be keeping a close eye on:•    Persistent Coughing•    Presence of blood or mucus when coughing•    Loss of appetite resulting to weight loss•    Feeling of shortness of breath•    Pneumonia, bronchitis, or other respiratory-related illness•    Constant pain in the chest, back, or neck•    Uncharacteristic feverYou need to pay close attention to any changes in your body though, since most of the symptoms are not evident until they have reached the advanced stage. Once you have determined these symptoms, there are essential steps and further information you need to know. Spread of Lung CancerLung cancer is caused by the presence of cancer cells. These abnormal cells continue to divide on their own without following a particular order or pattern. Because of this nature in the cells, they have the potential to destroy the neighboring tissues of the body. In fact, they can also develop into a malignant tumor which can invade your bloodstream and cripple the lymphatic system. The process known as metastasizing is responsible for the spread of cancer cells such that the initial cancer tumor can cause the growth of new tumors in various parts of the body. In terms of determining the rate at which these cancer cells spread, it largely depends on the type of cells. But on average, tumor growth can happen in a span of a few months. When To Consult A DoctorAs soon as you notice any of the symptoms listed above, it is best to meet with your doctor immediately. This will allow them to make diagnosis or assess your condition. Furthermore, the earlier you act on any lung cancer warning signs or symptoms, the more capable you are at preventing it from getting worse. Immediate consultation with your doctor will enable them to further investigate the reason for such symptoms to exclude other health conditions. Below is a list of what is recognized as late-stage lung cancer symptoms. One needs to work together with their physician to avoid reaching this stage:•    Inexplainable feeling of fatigue•    Reduced appetite•    Aches in your joints,bones, or constant headaches•    Bone fractures that are not brought about by injury•    Swelling on your face or neck•    Abnormalities in your neurologic conditionsTests for Lung CancerOnce you have seen with your doctor, the following tests are conducted to diagnose you:1) Chest x-ray: This is mostly done for patients with complaints on excessive coughing and shortness of breath.2) CAT Scan: This method of scanning in such areas as chest, head, abdomen, or pelvis helps assess the size of a tumor or evaluate how farther it has spread. 3) Bronchoscopy: In this method, your physician creates a direct visualization of your airways after numbing medications or sedations are administered. 4) PET Scan: This tool is used for assessing the tumor, which also utilize a chemical known as radionuclide. As soon as your first lung cancer warning signs become evident, it is best to undergo this test to help prevent the rapid growth of tumors.

Lung cancer is a serious health problem, it is essentially the growth of abnormal cells in the lungs.

This growth of unhealthy cells can start anywhere in the lungs.

Lung cancer is actually the leading cause of cancer deaths in both men and women. Of those people who contract lung cancer, less than half of them survive one year. The quicker you notice symptom and have it diagnosed, the quicker treatment can begin and the odds improve.

The leading cause of lung cancer is smoking. eighty seven percent of people who have lung cancer have gotten it from smoking.

If a person smokes a pack a day, they have twenty times the risk of getting lung cancer or some other serious health problem than a person who doesn’t smoke at all.

There are so many carcinogens in tobacco smoke that they constantly damage the healthy cells of the lungs, and the risk goes up for smokers depending on how long they have smoked and how much they have smoked.

There are other causes of lung cancer for healthy people who don’t smoke

These causes include asbestos, which used to be used in building materials. It enters a healthy person’s lungs by inhaling, and then attaches to the respiratory lining.

People who get lung cancer from asbestos exposure usually get it from work or from living in an older home.

Some doctors also think that women who are exposed to tobacco smoke, are more likely to have lung cancer than men exposed to smoke. Researchers have found a gene called GRPR which causes unusual cell growth in people exposed to cigarette smoke. This gene is more active in women than in men and may explain why females are more prone to lung cancer.

Some research has indicated a diet low in fruit and vegetables may increase the chances of developing cancer if exposed to tobacco smoke. Some evidence shows fruit and vegetables may protect against lung cancer.

The final cause of lung cancer in healthy people is radon exposure.

Radon is a gas which is naturally released from soil and rocks. In closed spaces like caves, basements and other areas, it can become concentrated and cause lung cancer or other health problems. It is always a good idea to have a home checked for radon levels because there are things that can be done to lower them to more acceptable levels.

The good news?

When smokers quit smoking, their risk for getting lung cancer goes down immediately and every year that they don’t smoke.

It is also an interesting fact that 25% of nonsmokers that get lung cancer live with smokers, so the secondhand smoke is most likely the cause of their lung cancer health issues.

Unlike other forms of lung cancer, metastatic lung cancer is the result of a cancer from another part of the body spreading to the lungs. When a malignancy develops in the body (most often in the breasts, colon, prostate, or bladder, though almost all cancers have the ability to spread) it can sometimes spread through the blood stream. When these malignancies settle into the pulmonary tissues, such as the alveoli (the final vein-like branches of the respiratory system) and the supporting tissues of the respiratory structures, the cancer has metastasized to the lungs.

Unfortunately, treating metastatic lung cancer presents significant challenges. Since the cancer has spread from another part of the body, treatment not only involves addressing the cancer in the lungs, but also the original cancer and any other areas of the body that may have also become affected. In some cases, if the primary tumor is successfully removed and if the spread of the tumor cells to the pulmonary regions is relatively localized, then the management of the cancer by surgical techniques may do the job. However, if the metastatic lung cancer is extensive, because so many areas of the body may be under the influence of the cancer, certain treatments (such as surgery, and in many cases, radiation therapy as well) may prove ineffective. Which leaves most patients with chemotherapy as the primary treatment of choice.

Chemotherapy often uses a combination of drugs (often referred to as “anti-cancer” drugs) to kill cancer cells, though a single drug may be used as well. While the aim of these drugs is to stop cancerous cells from multiplying, they also can damage healthy cells. This is what creates the side effects that are often associated with chemotherapy, such as the loss of hair, nausea and vomiting, and fatigue. The good news, however, is that the healthy cells will generally repair themselves once the chemotherapy process is over.

Chemotherapy can provide a cure (when the cancer disappears and does not return) or help to control the cancer (to keep it from spreading and perhaps kill cancerous cells that have already spread to other areas of the body, such as is the case in metastasized lung cancer) or relieve the symptoms of the cancer (to provide the patient with a better quality of life, even in the face of a poor prognosis). How it’s used in any particular situation is dependent upon the type of cancer, the stage of the cancer, the prognosis, and the plan as set out by the patient and his or her physician.

In addition, there are complementary and alternative treatments. These can include everything from proper nutrition to pain management, from spiritual approaches to natural herbs and supplements. Of course, such alternative plans will vary much the same as traditional treatments, depending on the location and size of the tumor, the age and general health of the patient, and other factors.

Metastatic lung cancer is certainly more challenging to overcome than other forms of lung cancer because the fight against the cancerous cells is not confined to the lungs. And while a cure is unlikely in most cases, in rare instances (usually when the primary tumor has been removed and the spread of the cancer has been limited), the lung metastases can be removed surgically, with a prognosis of long-term survival.

Smoking is BAD! Is there still a living soul that doesn’t know and understand this? There can’t be. The media won’t let such a thing happen. Just take a gander at all the anti-smoking commercials aired daily. If they don’t get the point across, nothing will. As we all know, smoking leads to lung cancer. It’s not exclusively for those with poor genetics or smokers over the age of 65. It can apply to anyone who lights up regularly. One measly cigarette will taint your lungs for a full month. Imagine what a pack a day will do to them. We’re talking some serious damage here. So, if you’re still on the fence about smoking, I think it’s time for a few recent articles on lung cancer.

A surprising finding is that if your parents smoked in the house during your childhood and adolescence, your risk of lung cancer is double as an adult even if you yourself don’t smoke. Parents, think again lighting up your next cigarette! This year, lung cancer will kill about 163,500 Americans and remains the number one cause of cancer deaths taking more lives than colon, breast, and prostate cancers combined.

More than one billion people worldwide are smokers even though nine out of ten lung cancer deaths are caused by smoking. By the year 2020 it’s estimated that as many as ten million people a year will die of smoking related diseases unless radical action is taken to curb the advance of the mega-bucks tobacco industry into Third World countries. About three quarters of those ten million deaths will be in developing nations.

I love to read. Not just novels and the Sunday paper. I mean I really like to read and learn about new things. It’s refreshing and I need to know what’s happening in the world today. If it’s not articles on lung cancer, its break-throughs regarding heart disease or prostate enlargement.

I learned a little bit about how diet affects lung cancer. An apple a day may keep lung cancer away. A Finnish study suggests that apples not only keep doctors away, but provide protection for the lungs as well. This study found that people who ate the most apples were 58 % less likely to develop lung cancer. Other studies suggest that lung cancer risk is lower among smokers and non smokers who ate at least 5 servings of vegetables and fruits daily.

It’s always prudent to add new data to the brain banks. This way you don’t wander through life like a naive, uninformed dolt. You prevent things before they occur, and you seek the newest medications upon the detection of a health affliction. With some health issues, it’s pretty cut and dry. One would think that common sense would overrule, but apparently it doesn’t. If it did, folks wouldn’t still be smoking like chimneys. Some individuals just need a scare before they can get on the smoke-free bandwagon. If current articles on lung cancer won’t do the trick, maybe respiratory problems will.

Make sure you get tested for lung cancer. In approximately 25% of people with lung cancer, there are no symptoms and the cancer is detected during screening or a routine physical examination. However, in three-quarters of lung cancer patients there are warning symptoms and signs that can alert the patient or their physician.

One of the most amusing things I’ve ever seen is a person smoking through the hole cut out of their throat. Now that’s bright! Obviously some people have a horrible time kicking the habit. However, there is irrefutable evidence linking smoking to serious health afflictions. Any articles on lung cancer, asthma and Bronchitis can inform you of this. We need to work toward a smoke-free environment, because all the rest of us are being assaulted by the second-hand stuff. That’s not right! Kick the habit before it kicks you off the primordial coil.

Our lung is one of the main “motors” of our body. Yet, often it is not given due attention and care, and it remains in the background when it comes to issues of the hearth or brain.
The main function of our lung is to exchange the gases between the air we breathe and our blood. It is through our lung that carbon dioxide is emptied from our body and oxygen is transported to our blood vessels. It is not widely known that the two sides of our lung are not identical to each other. The right lung has three lobes, whereas the left lung has two lobes, and an additional portion which is called the lingula which is like the middle lobe.
Lung cancer is the leading type of cancer causing death among men and women of the world. It is only since the 1930s that cases of lung cancer started to increase. This is mainly due to tobacco consumption, and the much disputed pollution and smog around the globe. 90% of lung cancers are caused by smoking. Recently, governments and states around the globe have raised the price of tobacco dramatically, having some significant effect on societies in cutting down on tobacco smoking.
Some people mistakenly believe that pipe and cigar smoking do not have such a harmful effect on the lungs as cigarettes. Cigar and pipe smokers are at 5% higher risk to die of lung cancer than non-smokers. This ratio is 25% for people smoking cigarettes.
Passive smokers, i.e., smokers who do not smoke themselves but stay in an environment where others smoke, and inhale smoke, are at 24% higher risk of developing cancer (only 1% less than a cigarette smoker.)
Other danger factors in developing cancer are asbestos fibres, radon gas, familial predispositions (genetic), and other lung diseases, along with air pollution.
Lung cancers are categorized into two types. Small cell and non-small cell lung cancer. This distinction is based on the appearance of the cells under microscopic examination and the appearance of tumor cells. The two types of cancers spread and grow in different ways, thus the distinction.
Small cell cancer is the most aggressive and rapidly growing type of cancers, and it makes up 20% of related cancers. It tends to grow first in the larger breathing tubes and grows very fast spreading around a large area. In its initial stage, it is more sensitive to chemotherapy, but it often bears worse prognosis. This type of cancer is mainly related with smoking.
On the other hand, for non-small cell lung cancer, the prognosis is poor. Patients treated with chemotherapy live generally only three months longer than those who do not get treatment. This type is divided into further two types, one starting from the larger breathing tubes but spreading around slower. This means that the size of these tumors varies when diagnosed. 50-60% of non-small cell cancer starts growing around the gas-exchanging surface of the lung. This form is most common for smokers, and along these there are female non-smokers who are mainly affected.
Our lung is a very sensitive organ, it is often the landing place for metastasis (when cancer cells break away from the primary tumor) of cancer originating from other parts of the body. In this case, we name it by the originating part of the body, for example breast cancer.
Cancer is a sly disease. Women can develop ovary cancer from the originating stomach cancer. It strikes the most innocent, the best sportsman, the firmest vegetarian, anyone without mercy. If it takes your lungs, it takes your breath. Do not give it a chance.

There are a various risk factors that are linked to lung cancer. The most common known causes are as follows:

Cigarette Smoking
Cigarette smoking is probably the most closely related link to developing lung cancer. A person who smokes two packs or more of cigarettes per day has a one in seven chance of developing lung cancer. Those that smoke one pack of cigarettes per day have a twenty-five times greater chance of developing lung cancer than a non-smoker. In addition, those people that smoke a pipe or cigar have a five times greater chance of developing lung cancer than a non-smoker.

The risk of developing lung cancer increases with the number of cigarettes smoked over your lifetime. Cigarette smoking damages the cells in your lungs. The moment you stop smoking, your lungs begin healing themselves, replacing damaged cells with healthy, normal cells. Your risk of developing lung cancer begins decreasing almost immediately when you quit smoking. Every year that you do not smoke, your chances of developing lung cancer drop further. By the fifteenth year, your chances of developing lung cancer are about the same as those of a person who has never smoked.

Secondhand Smoke
Also known as passive smoking, people exposed to secondhand smoke on a regular basis will have a higher risk of developing lung cancer, even if they do not smoke themselves. Studies have shown that those who live with a smoker have a 24% greater risk of developing lung cancer than most non-smokers. Doctors estimate that about 3000 lung cancer deaths a year are related to secondhand smoke.

Asbestos Exposure
Exposure to asbestos is another well-known cause of lung cancer and mesothelioma – cancer of the pleural lining of the lungs. Asbestos was widely used in construction and everyday products in the late 1800s through the 1960s. Asbestos separates into fine silica fibers that become trapped in the tissues of the lungs. Mesothelioma is inextricably linked to asbestos exposure. There are no reported cases of mesothelioma in people who were not exposed to asbestos either in the workplace or through their environment. A non-smoker who was exposed to asbestos has a five times greater risk of developing lung cancer than a non-smoker who was not exposed. Smoking increases the risk dramatically – a smoker who was exposed to asbestos has a risk of developing lung cancer that is 50 to 90 times greater than that of a non-smoker.

Radon Gas
It is estimated that about 12% of lung cancer deaths can be attributed to radon gas, a colorless, odorless gas that is a natural byproduct of the decay of uranium. The U.S. Environmental Protection Agency estimates that as many as 15% of homes in the United States have unsafe levels of radon gas, which will account for 15,000 to 22,000 deaths from lung cancer annually.

Air Pollution
Scientists estimate that as many as 1% of all lung cancer deaths are attributable to air pollution. They believe that prolonged exposure to very polluted air can raise the risks of developing lung cancer to about the levels of a passive smoker.

Lung cancer is a very deadly disease. The most significant risk factor of this disease is cigarette smoking. Lung cancer proves to be one of the most deadly health problems among Americans.

Studies show that lung cancer account for twenty-eight percent of all cancer deaths among American men and women.

Records further show that lung cancer is the most lethal malignant tumor worldwide causing up to three million deaths annually.

Even with the recognition that cigarette smoking is the major risk factor of lung cancer, it is important to note that not all smokers die of lung cancer but just the same, not all non-smokers are safe from lung cancer.

It is further important to recognize that early symptoms of lung cancer will help ensure proper management of this health risk condition.

Doctors believe that detection of early symptoms of lung cancer will help halt the progression of lung cancer and put the symptoms to remission.

There are various treatments available against this disease but if you will neglect the early symptoms of lung cancer, it may be hard to manage and possibly, it is already impossible to control. This is because advanced stage of the disease already involves secondary cancer sites developed in the other parts of the body.

Various treatments include surgery, chemotherapy, radiation therapy, immunotherapy, radio immunotherapy and the new lung cancer treatment, photodynamic therapy.

All of these lung cancer treatments will become useless especially if the detection of the cancer is already on its advanced stage.

Thus, it is necessary to recognize early symptoms of lung cancer to ensure you will be able to halt the symptoms and not merely lessen the symptoms.

Early symptom of lung cancer such as persistent coughing is commonly associated with mere itchiness of the throat from smoking. This makes smokers neglect it and set it aside.

Most smokers commonly worry about lung cancer symptoms only when they see blood in the sputum. Do not fall prey to this situation because when you finally see blood in the sputum, this means that you are already on the advanced stage of the lung cancer.

Other common early symptoms of lung cancer that is often neglected are sudden weight loss, chest pain and constant fatigue, when you start feeling all these signs and you are a smoker, you may need to see your doctor and have him test you for possible signs of lung cancer.

The next symptoms of lung cancer, which will point to an advanced stage of the disease are recurring cases of pneumonia or bronchitis, and neck and facial swelling.

Ensure that you will not neglect early symptoms of lung cancer to help you manage the disease properly. Visit your doctor if you are a smoker suffering from persistent coughing and constant fatigue.

Furthermore, if you are working in an environment where you are often exposed to impure air such as chemicals and asbestos ashes, even if you are not a smoker, you may need to check with your doctor when you feel anything similar to the early symptoms of lung cancer.

There is yet no known cure for this disease, thus detection of early symptoms of lung cancer is the only defence you have in order to avoid this lethal cancer from affecting your life.

It will also help to make sure you will not suffer from lung cancer if you minimize smoking or totally eradicate smoking from your life and live a healthy and active lifestyle.

Regular exercise and eating a well-balanced diet will ensure you will not suffer from lung cancer and will not experience even the early symptoms of lung cancer.
