If you wanted to cut down your risk for developing cancer, it would be best if you avoided
a. certain types of exercise
b. foods like fruits and vegetables
c. tobacco products
d. people with cancer

The answer is letter C. 

Tobacco products contain chemicals that trigger the overgrowth of cells inside the body. It is one of the most preventable causes of cancer and is often overlooked by many. Lung cancer is actually the leading cause of cancer deaths all over the world. Warnings and special indications should not be taken for granted when smoking. These are all meant to be there to prevent you from lighting that next stick which could well be a determinant on how long your life would be.
