Screening Colonoscopy

Colonoscopy and Colorectal Cancer Screening

Colorectal cancer is the third most common cancer among men and women in the US and it occurs most often in individuals over the age of 50. The U.S. Preventive Services Task Force recommends that individuals be screened for colon cancer starting at age 50. Recently, due to an increase in colon and rectal cancers among adults under age 50, the American Cancer Society is encouraging earlier screening at age 45. The good news is that regular screening through colonoscopy can prevent colorectal cancer. A polyp could take 10-15 years to develop into cancer. With a colonoscopy, your doctor can find and remove polyps before they reach the cancerous stage.
