Small Bowel Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 07/2021

ON THIS PAGE: You will find information about the number of people who are diagnosed with small bowel cancer each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

This year, an estimated 11,390 adults (6,130 men and 5,260 women) in the United States will be diagnosed with small bowel cancer. The disease makes up fewer than 10% of gastrointestinal tract cancers in the United States. The disease is diagnosed most often in people in their 60s and 70s.

It is estimated that 2,100 deaths (1,110 men and 990 women) from this disease will occur this year.

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for all types of small bowel cancer is 68%.

When detected at an early stage, the 5-year survival rate for small bowel cancer is 85%. If small bowel cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 76%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 42%.

As explained in the Introduction, there are several types of small bowel cancer, and survival rates are different for each. Talk with your doctor about the survival rate for your specific type of cancer.

It is important to remember that statistics on the survival rates for people with small bowel cancer are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information.
