What Is Stomach Cancer? TOPICS

How many people get stomach cancer?

The American Cancer Society’s estimates for stomach cancer in the United States for 2015 are:

  • About 24,590 new cases of stomach cancer
  • About 10,720 deaths from stomach cancer

This is a disease that mostly affects older people. About 6 out of 10 people found to have stomach cancer are 65 or older. The risk of a person getting stomach cancer in their lifetime is about 1 in 111, but it is slightly higher for men than for women.

Stomach cancer is much more common in other parts of the world. It was once a leading cause of cancer deaths in the United States, but it is now much less common. The reasons for this decline are not fully known, but they may be linked to more use of refrigeration for food storage and less use of salted and smoked foods. Some doctors think that an important factor is the use of antibiotics to treat infections. These drugs can kill the bacteria called H. pylori, which is thought to be a major cause of this disease.
