Colorectal cancer is a disease in which cells in the colon or rectum grow out of control [5]. It is sometimes called colon cancer, for short [2], and can also be referred to as colorectal cancer, which combines colon cancer and rectal cancer [1]. Colorectal cancers often begin as a growth called a polyp inside the colon or rectum [4] and finding and removing polyps can prevent colorectal cancer. The Colorectal Cancer Alliance raises awareness, provides support, and inspires efforts that fund critical research to end colorectal cancer [3]. Treatment options include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy and clinical trials. Screening tests are recommended by the USPSTF for people aged 50-75 years old with an average risk of developing colorectal cancer[6].

Colorectal cancer is a type of cancer that affects the colon and rectum. It is one of the most common types of cancer in both men and women, and it can be caused by a variety of factors including genetics, lifestyle choices, diet, and environmental exposures. Symptoms may include changes in bowel habits such as constipation or diarrhea, blood in the stool, abdominal pain or cramping, unexplained weight loss, fatigue or weakness. Treatment options vary depending on the stage of the disease but may include surgery to remove tumors or parts of affected organs; chemotherapy; radiation therapy; targeted therapies; immunotherapy; hormone therapy; and/or clinical trials.
