Surgery is the most common treatment for gastric cancer especially when the tumour is confined to the stomach.
Total gastrectomy surgery is done when the entire stomach needs to be removed. Partial gastrectomy surgery is done when only part of the affected stomach needs to be removed.
Radiation therapy can be used before the surgery to shrink the tumour. It can also be used after the surgery to kill the remaining cancer cells. Radiation therapy is often combined with chemotherapy. Radiation therapy can result in diarrhoea, indigestion, nausea and vomiting.
Chemotherapy can be used before the surgery to shrink the tumour. It can also be used after the surgery to kill the remaining cancer cells. The chemotherapy drug type is dependent on the type of cancer.
