Key Statistics for Small Intestine Cancer

Although the small intestine makes up the largest part of the gastrointestinal (GI) tract, small intestine cancers are rare in the United States. In fact, they account for fewer than 1 in 10 cancers of the gastrointestinal (GI) tract, and fewer than 1 in 100 cancers overall.

The American Cancer Society estimates for these cancers in the United States for 2018 are:

  • About 10,470 people in the United States will be diagnosed with some type of small intestine cancer.
  • About 1,450 people will die of small intestine cancer.

Cancers of the small intestine tend to occur more often in older people. They are most often found in people in their 60s and 70s.
