Stomach cancer, also known as gastric cancer, is a build-up of abnormal cells that form a mass in part of the stomach.
According to the World Health Organization (WHO), 723 000 cancer-related deaths are caused by stomach cancer each year worldwide. It is the fifth most common cancer worldwide, but the third leading cause of cancer-related deaths.
The highest stomach cancer rates in 2018 were seen in South Korea, Mongolia, Japan, and China. But the incidence is increasing in South East Asia, including Malaysia and Indonesia.
