Stomach cancer incorporates ICD-10 cancer codes C16 (Malignant neoplasm of stomach).
New cases
In 2019, there were 2,439 new cases of stomach cancer diagnosed in Australia (1,548 males and 891 females). In 2023, it is estimated that 2,576 new cases of stomach cancer will be diagnosed in Australia (1,647 males and 929 females). In 2023, it is estimated that a person has a 1 in 117 (or 0.85%) risk of being diagnosed with stomach cancer by the age of 85 (1 in 91 or 1.1% for males and 1 in 164 or 0.61% for females).
Notes
- Data sourced from AIHW Cancer Data in Australia 2023 web report and supplementary data tables
- More information about incidence rates for the most common cancers diagnosed can be found on the NCCI website in the ‘Cancer incidence’ section (https://ncci.canceraustralia.gov.au/diagnosis/cancer-incidence/cancer-incidence)
In 2019, the age-standardised incidence rate was 10 cases per 100,000 persons (14 for males and 7.1 for females). In 2023, it is estimated that the age-standardised incidence rate will be 9.8 cases per 100,000 persons (13 for males and 6.7 for females). The incidence rate for stomach cancer is expected to increase with age, highest for those aged 80–84 years.

The number of new cases of stomach cancer diagnosed increased from 1,824 (1,152 males and 672 females) in 1982 to 2,439 in 2019. Over the same period, the age-standardised incidence rate decreased from 21 cases per 100,000 persons (30 for males and 14 for females) in 1982 to 10 cases per 100,000 in 2019.
Deaths
In 2021, there were 1,208 deaths from stomach cancer in Australia (764 males and 444 females). In 2023, it is estimated that there will be 1,153 deaths (750 males and 403 females). In 2023, it is estimated that a person has a 1 in 280 (or 0.36%) risk of dying from stomach cancer by the age of 85 (1 in 213 or 0.47% for males and 1 in 411 or 0.24% for females).

- Two sources are used for cancer mortality reporting rankings (National Mortality Database and Australian Cancer Database). Mortality data reported for cancer of unknown primary site, liver cancer and stomach cancer in the chart above is from the Australian Cancer Database. Data from the National Mortality Database is presented in-text unless it is unavailable. More information can be found at AIHW interim guidelines (https://www.aihw.gov.au/reports/cancer/cancer-data-in-australia/contents/cancer-data-commentaries/interim-guidelines-choosing-which-mortality-data)
- More information about mortality rates for the most common causes of cancer death can be found on the NCCI website in the ‘Cancer mortality’ section (https://ncci.canceraustralia.gov.au/outcomes/cancer-mortality/cancer-mortality)
In 2021, the age-standardised mortality rate was 4.8 deaths per 100,000 persons (6.6 for males and 3.3 for females). In 2023, it is estimated that the age-standardised mortality rate will be 4.4 deaths per 100,000 persons (6.2 for males and 2.8 for females). The mortality rate for stomach cancer is expected to increase with age.

The number of deaths from stomach cancer increased from 1,398 (874 males and 524 females) in 1982 to 1,182 in 2020. Over the same period, the age-standardised mortality rate decreased from 12 deaths per 100,000 persons (18 for males and 8.1 for females) in 1982 to 3.7 deaths per 100,000 in 2020.
Survival
In 2015–2019, individuals diagnosed with stomach cancer had a 38% chance (36% for males and 41% for females) of surviving for five years compared to their counterparts in the general Australian population. Between 1990–1994 and 2015–2019, five-year relative survival for stomach cancer increased from 21% to 38%.

Prevalence
At the end of 2018, there were 1,818 people living who had been diagnosed with stomach cancer that year, 5,560 people living who had been diagnosed with stomach cancer in the previous 5 years (from 2014 to 2018) and 12,553 people living who had been diagnosed with stomach cancer in the previous 37 years (from 1982 to 2018).

The National Cancer Control Indicators (NCCI) are a set of indicators across the continuum of cancer care, from Prevention and Screening through to Diagnosis, Treatment, Psychosocial care, Research and Outcomes. The NCCI website allows users to see visual representations of data on each indicator through interactive charts.
