2,294 new cases of stomach cancer are estimated to be diagnosed in Australia this year.
Stomach cancer occurs when abnormal cells in the stomach grow in an uncontrolled way. There are two main types of stomach cancer. Gastric cancer develops in the glandular calls that line the stomach wall, whilst gastrointestinal stromal tumours are rare cancers that develop in the connective tissue in the stomach wall.
Stomach cancer occurs in males and females, but is almost twice as common in males. It is estimated that in 2017, 2,294 new cases of stomach cancer (1,494 males and 800 females) will be diagnosed.
