Stomach Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 01/2020

ON THIS PAGE: You will find information about the number of people who are diagnosed with stomach 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 27,600 (16,980 men and 10,620 women) in the United States will be diagnosed with stomach cancer.

It is estimated that 11,010 deaths (6,650 men and 4,360 women) from this disease will occur this year.

Stomach cancer occurs most often in older people. About 60% of people who are diagnosed are older than age 64. The average age of diagnosis is 68.

The incidence of stomach cancer varies in different parts of the world. Although stomach cancer has decreased in the United States by 1.5% annually over the last decade, it is still common in other countries and one of the top causes of cancer deaths 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 32%. 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 69%. 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 has spread 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. Talk with your doctor if you have any questions about this information.
