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.
The lifetime risk of developing stomach cancer is higher in men (about 1 in 96) than in women (about 1 in 152). But each person's risk can be affected by many other factors.
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.
For much of the early 20th century, stomach cancer was the leading cause of cancer death in the United States, but today it is well down on this list. The reasons for this aren't completely clear, but two main factors are thought to have been important:
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.
