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 on the side of your screen.

This year, an estimated 26,370 (16,480 men and 9,890 women) in the United States will be diagnosed with stomach cancer.

It is estimated that 10,730 deaths (6,540 men and 4,190 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 29%. 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 5-year survival rate is 65%. If the cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 30%. 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 how many people survive this type of cancer are an estimate. The estimate comes from data based on thousands of people with this cancer in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with stomach cancer. Also, experts measure the survival statistics every 5 years. This means that the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Learn more about understanding statistics.
