With the help of modern medicine lung cancer can be controlled and even cured depending on the size of the tumor. The main risk factors included in the growth of lung cancer is usage of tobacco, cigarette smoking and also exposure to second hand smoke or passive smoking.

Tobacco smoke can cause small cell cancer and also non small cell lung cancer in people. Lung cancer does not have any early symptoms and it is very difficult to diagnose it in the early stages. Once it reaches the final stages then it starts showing the symptoms rather aggressively. When the symptoms do show up doctors are almost sure that it could be lung cancer and the patient’s smoking history is immediately taken into account while diagnosing it.

After diagnosing the cancer, the first thing the doctor does is to find out if it had spread to the other parts of the body and this is when it is determined at what stage of lung cancer the patient is in. this process is called staging for cancer. Lung cancer has high potential to spread to the brain and the bones. The best form of treatment for lung cancer is surgery especially when it is in its early stages where the tumor can be removed and it has not spread to the other parts of the body. The effects of surgery are seldom long lasting in lung cancer and there is lot of chances that the patient will recover completely.
