Gastric cancer (or stomach cancer) is the Tenth most common cancer in Malaysia, affecting 3.3% of all cancer incidences (National Cancer Registry Report 2007-2011). Fairly uncommon compared to breast or lung cancer, gastric cancer still poses a signiﬁcant health problem as it contributed to 0.68% of total deaths in our country in 2014 (WHO 2014).
The stomach is located in the upper abdomen and is part of the digestive system. Food is channelled through the oesophagus to the stomach where it gets partially digested before reaching the intestine. Cancer develops in cells of the stomach wall and subsequently invade through the wall, onto the adjacent organs, such as the liver, pancreas or the oesophagus. Some malignant cells may enter blood or lymphatic vessels to spread (metastasis) to lymph nodes or distant organs such as the bones or lungs.
