Treatment for stomach cancer depends on the stage of the cancer, the patient’s general health and other factors such as age and personal preferences. The main treatment options for stomach cancer are:

Surgery: Surgery is the most common treatment for stomach cancer. The type of surgery depends on the stage and location of the cancer. In some cases, partial or total gastrectomy, which involves removing part or all of the stomach, may be necessary.

Radiation therapy: Radiation therapy uses high-energy X-rays or other forms of radiation to kill cancer cells. It can be used alone or in combination with surgery or chemotherapy. External beam radiation therapy is the most common type of radiation therapy for stomach cancer.

Chemotherapy: Chemotherapy uses drugs to kill cancer cells. It can be given alone or in combination with radiation therapy or surgery. Chemotherapy is usually used to treat advanced stomach cancer or when the cancer has spread to other parts of the body.

Targeted therapy: Targeted therapy is a newer type of cancer treatment that targets specific molecules or proteins involved in the growth and spread of cancer cells. It is not yet widely used for stomach cancer, but clinical trials are ongoing.

Immunotherapy: Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancer. It is not yet widely used for stomach cancer, but clinical trials are ongoing.

It is important to discuss all treatment options with your healthcare team to determine the best course of action for your individual situation.
