“Cigarette smoking is dangerous for your health”.

We hear that advisory all the time. There is that emphasis on the word - “dangerous”. Indeed cigarette smoking is one of the reasons why lung cancer takes place. About 90 percent of lung cancers are connected with smoking. Indeed, lung cancer is not an easy matter. It destroys. It kills.

Lung cancer is the unstoppable growth of abnormal and malformed cells in one or both lungs. Such cells multiply at a rapid speed until a tumor is formed, disrupting the lung and making it function malevolently.

Risk factors of lung cancer include smoking nonstop, exposure to asbestos and radon gas, exposure to arsenic and other industrial components, exposure to radiation, air pollution and having been diagnosed with tuberculosis. Take note that there were 163, 510 cases of lung caner reported in 2005, making it one of the most common and pronounced killer diseases in America.

There are different types of lung cancer. Lung cancer can be categorized into two: non-small cell lung cancer and small-cell lung cancer.

Non-small cell lung cancer makes up eighty percent of this disease. The tumors involved are the following: epidermold carcinoma (or squamous cell carcinoma) that is seen in the bronchial tubes’ lining and known as the most prevalent among men; adenocarcinoma which is located in the lungs’ mucus glands and is very common among women; bronchioalveolar carcinoma and large-cell undifferentiated carcinomas.

Twenty percent of lung cancers belongs to the small cell lung cancer category. The cells involved are small but they grow at a fast rate and become big tumors in a short time. Smoking accounts for this lung cancer type.
