Number of New Cases and Deaths per 100,000: The number of new cases of stomach cancer was 7.2 per 100,000 men and women per year. The number of deaths was 3.2 per 100,000 men and women per year. These rates are age-adjusted and based on 2011-2015 cases and deaths.

Lifetime Risk of Developing Cancer: Approximately 0.8 percent of men and women will be diagnosed with stomach cancer at some point during their lifetime, based on 2013-2015 data.

Prevalence of This Cancer: In 2015, there were an estimated 97,915 people living with stomach cancer in the United States.

Survival Statistics

How Many People Survive 5 Years Or More after Being Diagnosed with Stomach Cancer?

Relative survival statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.

Additional Information

Survival by Stage

Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. The earlier stomach cancer is caught, the better chance a person has of surviving five years after being diagnosed. For stomach cancer, 27.6% are diagnosed at the local stage. The 5-year survival for localized stomach cancer is 68.1%.

Stomach cancer represents 1.5% of all new cancer cases in the U.S.

1.5%

In 2018, it is estimated that there will be 26,240 new cases of stomach cancer and an estimated 10,800 people will die of this disease.

Who Gets This Cancer?

Stomach cancer is more common in men than women and among other races and ethnicities than non-Hispanic whites. Age, diet and stomach disease, including infection with Helicobacter pylori can affect the risk of developing stomach cancer. The number of new cases of stomach cancer was 7.2 per 100,000 men and women per year based on 2011-2015 cases.

Trends in Rates

Changes Over Time

Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.

Using statistical models for analysis, rates for new stomach cancer cases have been falling on average 1.5% each year over the last 10 years. Death rates have been falling on average 2.3% each year over 2006-2015. 5-year survival trends are shown below.

More About This Cancer

Cancer and the Stomach

Figure: Anatomy of the Digestive System

Figure: Gastrointestinal (digestive) system anatomy; shows esophagus, liver, stomach, large intestine, and small intestine.

The wall of the stomach is made up of 3 layers of tissue: the mucosal (innermost) layer, the muscularis (middle) layer, and the serosal (outermost) layer. Gastric cancer begins in the cells lining the mucosal layer and spreads through the outer layers as it grows.

Stromal tumors of the stomach begin in supporting connective tissue and are treated differently from gastric cancer. See the PDQ summary on Gastrointestinal Stromal Tumors Treatment for more information.
