This presentation provides an overview of colon cancer including what it is, symptoms, causes, prevention, and treatment. Colon cancer is the second leading cause of cancer deaths in the US and usually develops slowly over several years in people over 50. Symptoms can include rectal bleeding, changes in bowel habits, and fatigue. Risk factors include family history, diet high in fat/red meat, lack of exercise, smoking, and heavy alcohol use. Screening, diet/exercise, and medications can help prevent colon cancer. Treatment depends on stage and may involve surgery, radiation, chemotherapy, or palliative care to relieve symptoms.
