About stomach cancer

What is the stomach?

The stomach is part of your digestive system. It is a hollow organ shaped like a bag that goes from the end of your oesophagus to the start of your small bowel. In the stomach, glands make chemicals, such as enzymes and acids, to help break down food. The stomach lining also makes a type of protein called intrinsic factor. This helps to absorb vitamin B12 into your bloodstream needed by red blood cells and your nervous system.

What is stomach cancer?

Stomach cancer is also known as gastric cancer. It happens when cells in the stomach change and start to grow quickly. They can then form a tumour. A malignant tumour is also known as cancer. The tumour can affect how the stomach works and cause problems for you. There are also different types of stomach cancer. Adenocarcinoma is the most common type and is found in the gland cells of the stomach.
