Stomach Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 04/2015

ON THIS PAGE: You will find information about how many people are diagnosed with this type of cancer each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

This year, an estimated 24,590 (15,540 men and 9,050 women) in the United States will be diagnosed with stomach cancer. It is estimated that 10,720 deaths (6,500 men and 4,220 women) from this disease will occur this year.

The incidence of stomach cancer varies in different parts of the world. Although stomach cancer is decreasing in Western countries, it is still one of the most common cancer types worldwide. 

The five-year survival rate is the percentage of people who survive at least five years after the cancer is found. The five-year survival rate of all people with stomach cancer is about 28%. This statistic reflects the fact that most people with stomach cancer are diagnosed after the cancer has already spread to other parts of the body. If stomach cancer is found before it has spread, the five-year survival rate is generally higher but depends on the stage of the cancer found during surgery. 

If the cancer is diagnosed and treated before it has spread outside the stomach, the five-year survival rate is 64%. If the cancer has spread to the surrounding organs or tissue (regional spread), the five-year survival rate is 29%. If the cancer has spread to parts of the body far away from the stomach (distant spread), the five-year survival rate is 4%.

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of cancer in the United States each year, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with stomach cancer. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of this cancer. Learn more about understanding statistics.
