— Colorectal cancer – cancer of the large intestine and rectum – is the third most commonly diagnosed cancer in the United States.
According to the American Cancer Society, colorectal cancer will account for more than 50,000 deaths this year. But there is reason for optimism as cancer screenings, lifestyle changes and added awareness can decrease your risk for colorectal cancer.
