The lungs are two sponge-like organs found in the chest cavity. The lungs bring air in and out, taking in oxygen and getting rid of carbon dioxide gas, a waste product of the body. It divides into tubes called the bronchi, which divide into smaller branches called the bronchioles.
It is smaller because the heart takes up more room on that side of the body.
Lung cancer is usually divided into two major types.

Lung Cancer occurs when the cells within an organism undergo mutations that cause the cell not to perform their regular duties.
The disease tends to be most frequent in highly developed countries (HDC), and less common in least developing countries (LDC), especially Africa and South America.
The low rates of lung cancer in LDCs are similar to United States rates in the 1930s, when rates of lung cancer were “under 5 cases per 100,000 for both sexes.
In contrast, African-Americans in the United States, an epicenter of the disease, now experience lung cancer incidence rates that are among the highest in the world.”4 Lung cancer is begining to dicrease in LDCs, but the number of incidences has become incredibly high in HDC, specially the United Stated of America.
Treatment for lung cancer comes in various forms depending on how advanced the cancer is.
