Colon cancer is not a common topic of conversation, but it is a fairly common type of cancer. According to the American Cancer Society (ACS), about 102,480 new cases of colon cancer are diagnosed each year. When coupled with rectal cancer, which accounts for about 40,340 new cases annually, colorectal cancer is the third most common cancer found in men and women, excluding skin cancers. If you were born in 1964, you will turn the big 5-0 this year. Even if you aren’t ready to sign up for an AARP membership card, you should undergo a colorectal cancer screening. That is because your chances of developing the disease increase considerably after reaching the half-century mark. In fact, according to the American Cancer Society, about 9 out of 10 people diagnosed with colorectal cancer are at least 50-years-old.
