Do you have a friend or family member who has been diagnosed with colorectal cancer? For most of us, the disease has touched someone close to us or in our lives. Colorectal cancer is the third most commonly diagnosed cancer in the United States in both men and women. This year we can expect to see over 100,000 new cases of colon cancer and over 40,000 new cases of rectal cancer. Over a lifetime, Americans have about a 5% (1 in 20) risk of colorectal cancer.
