Colorectal Cancer Screening
Cmdr. Candida Ferguson, a general surgeon at Naval Hospital Jacksonville, talks with a patient about colorectal cancer screening. Regular screening (with a stool test, sigmoidoscopy, or colonoscopy), beginning at age 45, is the key to preventing colorectal cancer and finding it early. Talk with your doctor about which test is right for you. (U.S. Navy photo by Deidre Smith)
