The American Cancer Society’s estimates for stomach cancer (also known as gastric cancer) in the United States for 2023 are:
Stomach cancer accounts for about 1.5% of all new cancers diagnosed in the US each year.
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.

In the US, the number of new cases of stomach cancer has been dropping by about 1.5% each year over the last 10 years.

While stomach cancer has become less common in the US, it's still much more common in some other parts of the world, particularly in East Asia. It remains one of the leading causes of cancer-related deaths in the world.
