Which types of cancer should concern me the most?
The "c" word is always a concern -- as we mentioned before, men have a greater lifetime risk of cancer. When you exclude gender-specific cancers, men are about 60 percent more likely to get cancer and 70 percent more likely to die of cancer than women [source: Men's Health].
Lung cancer is more common in men than women for one simple reason -- more men smoke than women. If you're a smoker, don't wait until you start having symptoms such as wheezing or shortness of breath; ask your doctor to suggest ways to help you quit. While you can also get lung cancer from exposure to asbestos or radon, smoking accounts for the vast majority of cases.
Colorectal cancer is also more prevalent in men. The risk increases with age -- more than 90 percent of cases occur in men over the age of 50 [source: National Cancer Institute]. While family history is a part of your risk, so is obesity and a diet high in red and processed meats. After the age of 50, all men should be screened for colorectal cancer (if you have a family history of the disease or a history of rectal polyps, you may want to be screened earlier). There are three different screening options: a fecal occult blood test, a double-contrast barium enema or a colonoscopy. Decide which option is best for you with your doctor's advice.
