Lung cancer is one of the most common cancers. It is the second most diagnosed cancer in men and women after prostate and breast, respectively.

The average age of a person getting diagnosis of the disease is 71 years.
There are many risk factors connected with lung cancer-
smoking, passive smoking, and exposure to carcinogens like asbestos, chromium, uranium, radon gas and nickel.
In the United Stats, there are some variations in smoking habits amongst different races and ethnic groups. For instance, more African American men than Caucasian men smoke, but they smoke fewer cigarettes per day on average. African American and Caucasian women have given an account similar smoking rates.
Even if menthol cigarettes are more extensively applied amongst African Americans, African Americans have higher rates than Caucasians, even after results have been attuned for differences in smoking habits. In the United States differences in socioeconomic backgrounds might account for some of the variations in lung cancer rates amongst African American and Caucasian populations.
