Colon cancer patients who are 65 and older may benefit from a caregiver's involvement, and caregivers may ultimately have a major impact on patients' disease management, according to a survey of oncologists commissioned by the Alliance for Aging Research.
Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Cancerous tumors found in the colon or rectum also may spread to other parts of the body. Cancer of the colon and rectum (colorectal cancer) is a malignant tumor arising from the inner wall of the large intestine. If signs and symptoms of colon cancer do appear, they may include changes in bowel habits, blood in your stool, persistent cramping, gas or abdominal pain. Since colon cancer can grow for years without causing any symptoms, it's best to get regular colon cancer screenings.
