There symptoms may be caused due to other health conditions. However, if some of these signs are visible you must consult a doctor to clarify its cause.
Basically, lung cancers treatment options consists of radiation therapy, surgery, chemotherapy, or a combination of these therapies.
Most of the time radiation therapy is used in combination with surgery and/or chemotherapy. External beam radiation and Brachy therapy are the two major therapies used for treating the lung cancer.
If lung cancer is detected in the early stages surgery is conducted to remove the tumor. At this stage, the cancer is limited to the lungs. Once it travels beyond the chest to other organs, surgery is not considered as a right treatment.
Let's have a look on some of the key lung cancer risk factors in more detail.
It is believed that nine out of ten cases of lung cancer develop as a result of the patient being a smoker or has been a smoker. Smoking has a very strong connection with this dreaded disease.
Second hand smoke is also linked with smoking. Second hand smoke carries a high degree of carcinogens and other dangerous components. If you regularly inhale second hand smoke, you become a partner in many of the risks that accrue to smokers.
Asbestos exposure is one of the common factors for mesothelioma. Asbestos releases fine silica fibers into the air and when these fibers are inhaled they get stuck up within the lung tissues and cause mesothelioma.
Radon is a gas generated by the radioactive decay of uranium. According to an estimation of the US Environmental Protection Agency, almost one in seven homes in US has dangerous levels of radon.
These are the important risk factors in developing lung cancer.
The patient's chance of survival increases if the cancer is detected at an earlier stage. This is true of all cancer, but is specifically true of lung cancer because of its tendency to spread fast to other body organs.
There are fourlung cancer stages
This is the first and least life threatening stage, whereas Stage 4 is the most advanced stage of the disease showing a very poor prognosis.
Albeit Stage 1 is the treatable among the stages of lung cancer, it is yet a very serious disease even at this first stage.
Lung cancers are often triggered by affecting the lining of the bronchi. Some cancers also develop in the glands that are found underneath the bronchi lining.
Stage 2 lung cancer manifests a phase where the ailment has been limited to lung tissue and the lymph nodes inside the lung.
When the disease proliferates further, it spreads to lymph nodes outside the lung also. So stage 3 lung cancer cover three areas -- lung tissue, lymph nodes inside the lung and lymph nodes outside the lung.
The disease is said to have advanced to stage 4 lung cancer when it has spread well beyond the lungs and has affected other organs like the liver, bones, brain and other parts of the body.
It is best to detect the cancer well before it proliferates to stage 4 lung cancer. Early detection is the major factor to successful treatment.
The lung cancer survival rate is the lowest of all types of cancers. It is certainly a fatal disease. Approximately one third of all deaths are caused by lung cancer in terms of all cancers.
As far as lung cancer survival rate is concerned, the aggregate survival rate at the end of five years is merely 15%. Unlike, the five year survival rate for prostate cancer is 98%, for breast cancer is 87% and colon cancer is 62%. This is a clear signal of the devastating nature of lung cancer.
The vital truth is that an approximately 87% of all cases of lung cancer are occurred by smoking.
Next to smoking, radon gas exposure is the biggest factor resulting to lung cancer, according to the US Environmental Protection Agency. Over 20,000 deaths are caused due to radon every year.
One of the reasons for the low lung cancer survival rate is the truth that the disease is usually detected at an advanced stage, when treatment is difficult to yield any results. Over 50% of all cases are detected at stages 3B or 4 - and such cases have a five year survival rate of merely 5%.
Throughout the planet, the lowest incidence of lung cancer is Nigeria country. And Great Britain is counted as the country with highest lung cancer cases.
Given the very low lung cancer survival chance, the most plausible action one can take is to never start smoking. Or if you are already a smoker, give up smoking as soon as possible.

It hugely depends upon the histological type of cancer, the stage, and the patient's performance scenario. Only about 2% of those detected with lung cancer that has proliferated to other parts of the body are alive for five years after the diagnosis.
Survival rates have enhanced for non small-cell lung cancer because of advancements in combine radiation/chemotherapy treatment. Small cell lung cancer is very difficult to treat, nevertheless. Small cell is the most aggressive lung cancers, and many patients have been detected at a very advanced stage. Small cell lung cancer can be treated by both chemotherapy and radiation.
Small cell lung cancer (SCLC) is a fast-developing lung cancer that proliferates more rapidly than non-small cell lung cancer.
Different types of small cell lung cancer are:
Most of small cell lung cancers are the oat cell type.
Because SCLC spreads fast all over the body, treatment must comprise cancer-killing drugs (chemotherapy) administered orally or injected into the body.
Because the disease has generally proliferated by the time it is diagnosed, very limited patients having SCLC are helped by surgery. Surgery is advisable only when there is only one tumor that too has not spread. Chemotherapy or radiation therapy is required after surgery.
Combination of chemotherapy and radiation therapy is administered on people with extensive SCLC. However, the treatment is given to relieve symptoms. It cannot cure the disease.
The following are some of the tests conducted to detect lung cancer:
Though there is no sure method to prevent lung cancer, you can adopt some preventive measures to lessen the risk factor. The preventive measures are:
A disease like lung cancer affects your pocket badly. According to researchers’ report, an 18 month course of lung cancer treatment costs approximately $80,000. You have to spend an amount of $800.000 to increase life with cancer by one year. However, the amount varies from one case to another. It depends on the health care system you adopt.
Usually the side effects of lung cancer treatment are temporary. Some of the major side effects are:
