Doctors can not always explain why one person gets cancer and another does not. However, scientists have studied general patterns of cancer in the population to learn what things around us and what things we do in our lives may increase our chance of developing cancer.... http://www.lung-cancer-info.org

If it's a Primary Cancer it's probably caused by smoking. If it's secondary then it has been transmitted from another cancer. Look on Wikipedia for the rest of this article under 'Lung Cancer'
Lung cancer is a cancer of the lungs characterized by the presence of malignant tumours. Most commonly it is bronchogenic carcinoma (about 90%). Lung cancer is the most lethal of cancers worldwide, causing up to 3 million deaths annually. Only one in ten patients diagnosed with this disease will survive the next five years. Although lung cancer was previously an illness that affected predominately men, the lung cancer rate for women has been increasing in the last few decades, which has been attributed to the rising ratio of female to male smokers. More women die of lung cancer than any other cancer, including breast cancer, ovarian cancer and uterine cancers combined.[1]
Current research indicates that the factor with the greatest impact on risk of lung cancer is long-term exposure to inhaled carcinogens. The most common means of such exposure is tobacco smoke.
Treatment and prognosis depend upon the histological type of cancer and the stage (degree of spread). Possible treatment modalities include surgery, chemotherapy, and/or radiotherapy

Can't tell you much about lung cancer but I can show you the result on the human lung of smoking. If you smoke, take one white handkerchief, suck in some smoke and then blow it thru' the handkerchief while holding it against your pursed lips. The brown smudge is what your lungs look like at first with smoking. This brown soon turns to black. A smoker who coughs is coughing up lung tissue.
A non-smoker - that is a person who has never smoked, will have the same lung capacity at aged 60 as when 16.
Think about it.
