Stomach Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 05/2016

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

This year, an estimated 28,000 (17,750 men and 10,250 women) in the United States will be diagnosed with stomach cancer.

It is estimated that 10,960 deaths (6,720 men and 4,240 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 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 people with stomach cancer is 30%. 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 5-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 5-year survival rate is 67%. If the cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 31%. If the cancer to a distant part of the body, the 5-year survival rate is 5%.

It is important to remember that statistics on the survival rates for people with stomach 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. People should talk with their doctor if they have questions about this information.
