Many people are when it comes to colon cancer.
A recent British study described by Ananova indicates that nearly half of the population would feel uncomfortable discussing potential symptoms, such as changes in bowel habits, with their family doctor. Avoiding an embarrassing discussion or examination can cost someone a life if colon cancer goes undetected until it has spread. And the risk of dying from colon cancer is not insignificant. Even a single screening for colon cancer can save lives. An evaluation of 22 screening methods found that a single colonoscopy at age 55 would spot enough cancers early to lower colon cancer deaths 30 percent, according to a wire service story in the Philadelphia Inquirer .
