SEER Stat Fact Sheets: Stomach Cancer
Lifetime risk estimates are not available with the current statistics release, but will be added later when population data for older age groups are available.
Statistics at a GlanceShow More
At a Glance
- Estimated New Cases in 2016 26,370
- Estimated Deaths in 2016 10,730
Number of New Cases and Deaths per 100,000: The number of new cases of stomach cancer was 7.4 per 100,000 men and women per year. The number of deaths was 3.3 per 100,000 men and women per year. These rates are age-adjusted and based on 2009-2013 cases and deaths.
Lifetime Risk of Developing Cancer: Approximately 0.9 percent of men and women will be diagnosed with stomach cancer at some point during their lifetime, based on 2010-2012 data.
Prevalence of This Cancer: In 2013, there were an estimated 79,843 people living with stomach cancer in the United States.
Survival StatisticsShow More
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.
Based on data from SEER 18 2006-2012. Gray figures represent those who have died from stomach cancer. Green figures represent those who have survived 5 years or more.
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, 26.7% are diagnosed at the local stage. The 5-year survival for localized stomach cancer is 66.9%.
- Localized (27%)
Confined to Primary Site
- Regional (28%)
Spread to Regional Lymph Nodes
- Distant (35%)
Cancer Has Metastasized
- Unknown (10%)

How Common Is This Cancer?
Compared to other cancers, stomach cancer is relatively rare.
|Common Types of Cancer||Estimated New
|1.||Breast Cancer (Female)||246,660||40,450|
|2.||Lung and Bronchus Cancer||224,390||158,080|
|4.||Colon and Rectum Cancer||134,490||49,190|
|6.||Melanoma of the Skin||76,380||10,130|
|9.||Kidney and Renal Pelvis Cancer||62,700||14,240|
Stomach cancer represents 1.6% of all new cancer cases in the U.S.
In 2016, it is estimated that there will be 26,370 new cases of stomach cancer and an estimated 10,730 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 7.4 per 100,000 men and women per year based on 2009-2013 cases.
Stomach cancer is most frequently diagnosed among people aged 65-74.

Who Dies From This Cancer?
For stomach cancer, death rates increase with age. Stomach cancer is the fifteenth leading cause of cancer death in the United States. The number of deaths was 3.3 per 100,000 men and women per year based on 2009-2013 deaths.
The percent of stomach cancer deaths is highest among people aged 75-84.

Trends in RatesShow More
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 2.6% each year over 2004-2013. 5-year survival trends are shown below the figure.
|5-Year Relative Survival||14.3%||15.7%||17.6%||20.0%||21.9%||22.9%||28.2%||31.6%|

Cancer and the Stomach
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.

This factsheet focuses on population statistics that are based on the US population. Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. To see tailored statistics, browse the SEER Cancer Statistics Review. To see statistics for a specific state, go to the State Cancer Profiles.
The statistics presented in this factsheet are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. In some cases, different year spans may be used. Estimates for the current year are based on past data.
Cancer is a complex topic. There is a wide range of information available. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas.
