Key Statistics for Stomach Cancer

The American Cancer Society’s estimates for stomach cancer in the United States for 2018 are:

  • About 26,240 cases of stomach cancer will be diagnosed (16,520 in men and 9,720 in women)
  • About 10,800 people will die from this type of cancer (6,510 men and 4,290 women)

Stomach cancer mostly affects older people. The average age of people when they are diagnosed is 68.  About 6 of every 10 people diagnosed with stomach cancer each year are 65 or older. The risk that a man will will develop stomach cancer in their lifetime is about 1 in 95.  For women the chance is about 1 in 154. Bute each person's risk can be affected by certain other factors.

In the US, the number of new cases of stomach cancer have decreased about 1.5% each year over the last 10 years.  Stomach cancer is much more common in other parts of the world, particularly in less developed countries. It is one of the leading causes of cancer-related deaths in the world.

Until the late 1930s, stomach cancer was the leading cause of cancer death in the United States. Now, stomach cancer is well down on this list. The reasons for this decline are not completely known, but may be linked to increased use of refrigeration for food storage. This made fresh fruits and vegetables more available and decreased the use of salted and smoked foods. Some doctors think the decline may also be linked to the frequent use of antibiotics to treat infections. Antibiotics can kill the bacteria called Helicobacter pylori (H pylori), which is thought to be a major cause of stomach cancer.
