Can Small Intestine Cancer (Adenocarcinoma) Be Found Early?

(Note: This information is about small intestine cancers called adenocarcinomas. To learn about other types of cancer that can start in the small intestine, see Gastrointestinal Carcinoid Tumors, Gastrointestinal Stromal Tumors, or Non-Hodgkin Lymphoma.)

Screening is testing for diseases like cancer in people who do not have any symptoms. Screening tests can find some types of cancer early, when treatment is most likely to be effective. But small intestine adenocarcinomas are rare, and no effective screening tests have been found for these cancers, so routine testing for people without any symptoms is not recommended.

For people at high risk 

For people with certain inherited genetic syndromes who are at increased risk of small intestine cancer, doctors might recommend regular tests to look for cancer early, especially in the duodenum (the first part of the small intestine). Tests that might be done include upper endoscopy (in which a long tube with a tiny video camera on the end is passed down the throat, through the stomach, and into the duodenum), CT scans, and endoscopic ultrasound (EUS). See Tests for Small Intestine Cancer (Adenocarcinoma) to learn more about these tests.
