Small intestine cancer
Also known as: Malignant neoplasms of small intestine, unspecified
General information only. Anpheros does not diagnose and does not recommend treatment. Talk to a doctor or pharmacist about your situation. In an emergency, call 112 (or your local emergency number).
In short
The small intestine is a part of the digestive system that connects the stomach to the large intestine. Intestinal cancer is rare, but eating a high-fat diet, having Crohn's disease, having celiac disease, or having a history of colonic polyps can increase the risk. Possible signs of small intestine cancer include abdominal pain, weight loss for no reason, blood in the stool, and a lump in the abdomen. Imaging tests that create pictures of the small intestine and the area around it can help diagnose intestinal cancer and show whether it has spread. Surgery is the most common treatment, and additional options include chemotherapy, radiation therapy, or a combination.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
