    Colorectal cancer basics

    Colorectal cancer is a cancer that starts in the colon or rectum, which are parts of the digestive system. Unlike most cancers, colorectal cancer is often preventable with screening and highly treatable when detected early.

    Screening and prevention

    The best way to prevent colorectal cancer is getting screened on time. Screenings can also find cancer early when treatment is most effective. Most people should begin colorectal cancer screenings at age 45, but people with certain risk factors may need to start screening earlier.

    Treating colorectal cancer

    Colorectal cancer is highly treatable if caught early. There are many types of treatments for colorectal cancer, including surgery, chemo, radiation, and other therapies. Your treatment typically depends on the location of the cancer and the stage of diagnosis.

    Meredith’s legacy: A family’s mission to save lives

    I was diagnosed with stage-I colon cancer. Due to my cancer’s localized nature, it was relatively simple to treat. Had I ignored my doctor’s plea and waited to get screened, I could have been facing full-blown metastatic disease in just a few years, which is much harder to overcome.
