The American Cancer Society recommends the following:

No matter what stage of stomach cancer you have, treatment is available. The choice of treatment you receive depends on many factors. The location and the stage (extent of spread) of the tumor are very important. In choosing your treatment plan, you and your cancer care team will also take your age, general state of health, and personal preferences into account.

The main treatments for stomach cancer are surgery, chemotherapy, and radiation therapy. Often the best approach uses 2 or more of these treatment methods.

It is important that you understand the goal of your treatment — whether it is to cure your cancer or to relieve symptoms — before starting treatment. If the goal of your treatment is a cure, you will also receive treatment to relieve symptoms and side effects. If a cure is not possible, treatment is aimed at relieving symptoms, such as trouble eating, pain, or bleeding.

It is also important to have a team of doctors with different specialties involved in your care before plans for treating your stomach cancer are made. Most likely, a surgeon, medical oncologist, and possibly a radiation oncologist will collaborate on a treatment plan before the start of your treatment.
