Doctor's Notes on Colorectal Cancer in Children

Colorectal cancer is disease where malignant (cancer) cells arise from tissues of the colon and/or rectum and form tumors. The signs and symptoms of colorectal cancer in children usually depend on where the tumor forms. For example, tumors of the rectum or lower colon may cause pain in the abdomen, constipation and/or diarrhea while tumors of the part of the colon on the left side of the body may cause signs and symptoms of a lump in the abdomen, weight loss, nausea and vomiting, loss of appetite, blood in the stool and anemia. The child may also feel tired, dizzy and have fast or irregular heartbeat, shortness of breath and pale skin.

The cause or risk factors for childhood colorectal cancer are often part of an inherited syndrome. Some of the inherited syndromes include familial adenomatous polyposis, Lynch syndrome, Li-Fraumeni syndrome, MYH-associated polyposis, Turcot syndrome, Cowden syndrome, Juvenile polyposis syndrome and Peutz-Jeghers syndrome.
