Experts tend to stick to the the opinion that lung cancer occurs once the cells covering the lungs are being destroyed while a person is having a cigarette. The crux of the matter here is that cigarette smoke contains big amount of carcinogens – particular substances that cause cancer. Having inhaled them, you initiate the process of change in the lung tissue right away.

At first, your organism handles the situation successfully and manages to make up for the harm inflicted. However, being constantly exposed to the smoke results in normal cells being damaged to a great degree. As time goes by, these severely impaired cells start functioning abnormally thus leading to cancer.

Experts classify lung cancer into two groups. The crucial point is the way lung cancer cells look when an expert is studying them under microscope. Then, on the basis of the results, your doctor prescribes necessary treatment recommendations in accordance with your lung cancer type. In general, there are two main forms of lung cancer.

They are the following:

  • Small cell lung cancer occurs more rarely than non-small cell lung cancer and only if you are really smoking a lot.
  • Non-small cell lung cancer. Actually, this is a common term for several types of cancer that develop in the same way and have symptoms that coincide. Such cancer as SCC, glandular carcinoma and large cell carcinoma are all united under the term “non-small cell lung cancer”.
