The specific causes of cancers are still not fully understood. However, there have been lots of developments and research being done all over the world. Basically, cancer arises from the abnormal and uncontrolled division of cells which invade and destroy the surrounding tissues causing death.
There are different types of cancers, among them, the four most common cancers are breast cancer, colon cancer, lung cancer and prostate cancer. Out of them, lung cancer is very common and is associated with cigarette smoking.
Smoking can be very addictive without knowing about it. Many people start smoking for various reasons, for instance, they think that smoking can relieve them from depression or maybe they think it creates a cool self-expression.

There are two major types of Lung Cancers:
Small Cell Lung Cancers (SCLC)
Non-Small cell lung cancers (NSCLC)
Small Cell lung cancers:
Small Cell lung cancers, also known as oat cell carcinoma, are less common than non-small lung cancer. The cells grow more rapidly than NSLC throughout the body and spread to lymph nodes proceeding to other organs such as bones, brain, glands, and liver.
Non-Small cell lung cancers:
Non-Small cell lung cells are known to be very common cancers. The cells grow and spread slower than SCLC. They all grow and spread in different ways. Smoking is the primary reason for this type of lung cancer.
