Types of stomach cancer
There are different types of stomach cancer. 95% develop in the cells of the stomach lining.and are known as adenocarcinoma of the stomach.
Less common types include:
- lymphoma of the stomach, which develops in the lymphatic tissue (tissue that drains away fluid and helps fight infection)
- gastrointestinal stromal tumours (GISTs) – in the muscle or connective tissue of the stomach wall
Treatment
Most cases of stomach cancer are treated using surgery to remove some or all of the stomach. This is known as a gastrectomy.
You will still be able to eat normally after a gastrectomy but you will most likely have to adjust the size of your portions.
Chemotherapy is also commonly used before surgery to help shrink the tumour and sometimes after surgery to help prevent the cancer from returning.
Many cases of stomach cancer can not be completely cured, but it is still possible to relieve symptoms and improve quality of life using radiotherapy and in some cases also chemotherapy and surgery.
