2. Lung Cancer
The ACS estimates there will be 221, 200 new cases of lung cancer diagnosed in the U.S. during 2015. Lung cancer is the number one cause of cancer death among men and women in the U.S. There will be an estimated 158, 040 deaths attributed to lung cancer in 2015. There are two major types of lung cancer: non-small cell and small cell. Non-small cell lung cancer is the most common type, while small cell lung cancer grows faster and tends to spread in the early stages of disease.
Overall, the prognosis for lung cancer is bleak with 5-year survival rates for all stages being a dismal 16-percent. Cigarette smoking is the most significant risk factor for lung cancer. Non-smokers can contract lung cancer as a result of prolonged exposure to second-hand smoke. The USPSTF recommends annual screening for lung cancer with CT in adults 55 to 80-years old who have a 30-pack year smoking history.
