Stomach cancer, also known as gastric cancer, is cancer that starts in any part of the stomach. Infection with Helicobacter pylori is considered a possible risk factor for this cancer.
Diet appears to be one risk factor for stomach cancer. People who eat large amounts of smoked foods, salted fish and meat, and pickled vegetables seem to be at higher risk.
To make the diagnosis of stomach cancer, your doctor will take down your medical history, give you a physical exam, and order certain tests to rule out other conditions.
Your treatment choices depend on how far it has spread, as well as the way in which it grows. You may need surgery, chemotherapy, radiation therapy, or a combination of these.
Side effects are common during cancer treatment, and they vary from person to person. Your health care team will work to ease any side effects you experience.
