Stomach cancer treatment

The most important factor in planning treatment for stomach cancer is the stage of the disease, particularly whether the tumour has spread from its original location. Your treatment will also depend on your age, medical history and general health.

Surgery is the main treatment for stomach cancer that has not spread. If the cancer has spread, treatment will often include chemotherapy or radiation therapy, but not surgery.

Preparing for treatment

Improve diet and nutrition – People with stomach cancer often lose a lot of weight and can become malnourished. A dietitian can provide advice on ways to reduce the weight loss through changes to your diet, liquid supplements or a feeding tube. This will help improve your strength and lead to better treatment outcomes.

Stop smoking – If you are a smoker, you will be assisted to stop smoking before surgery. If you continue to smoke, you may not respond as well to treatment and smoking may make any side effects you experience worse. See your doctor, call the Quitline on 13 7848 or visit for support quitting.
