We don't know what causes all cancers, but we do know that lifestyle changes can greatly lessen your risk of some cancers.
Smoking causes more than eighty percent of lung cancer deaths.
Using smokeless tobacco greatly raises your risk of oral and throat cancer. To help prevent cancer, it is recommended to keep a desirable body weight and limit your total fat intake. Being excessively overweight can increase your risk of dying from prostate or other cancers. Eat high fiber foods such as whole grain breads and cereals, dried peas and beans, and fruits and vegetables. Five servings of fruits and vegetables a day, especially dark green and dark yellow vegetables and citrus fruits, can reduce your risk of colon, lung, and some other cancers.
