What are the treatments for Stomach Cancer?

If the patient is diagnosed of stomach cancer, doctor will suggest the following treatments to patient:
Stomach removal surgery
Stomach removal surgery is the most common treatment of stomach cancer. Doctor decides to remove a portion of or the entire stomach depending on the patient’s condition. During the surgery, doctor removes the tumor and the tissues and lymph nodes around.
In general, if the lesion is only limited to mucosa and submucosa, the cure rate of stomach removal surgery can be as high as 90%.
Radiotherapy
Radiotherapy uses high-powered radiation beams to destroy cancer cells. It may be used together with chemotherapy after surgery to prevent recurrence and enhance the survival rate after surgery.
Chemical anti-cancer drugs
Chemotherapy uses anti-cancer drugs to kill cancer cells and stop them from growing and dividing. There are drugs for oral administration and intravenous injection (injection of drugs into the bloodstream through a vein), mainly after surgery treatment, aiming at preventing recurrence and enhancing the survival rate after surgery. Chemotherapy can also be used as palliative treatment for relieving symptoms and prolonging life. A minority of patients may also benefit from target therapy.
