Colorectal cancer is virtually nonexistent at the equator.
It's not unusual to hear colorectal cancer survivors complain about diarrhea and pain for many years after surgery. For people with a family history of colorectal cancers, diet and exercise measures might not be enough. Though it's the fourth most common of all cancers, colorectal cancer is arguably the least publicized. Many people would be surprised to hear that major league baseball player Darryl Strawberry is a survivor of colon cancer, and have probably forgotten that President Reagan underwent successful surgery for it in 1985. That's because many colorectal cancer types are very slow growing and easily detectable in the very early stages.
