Stomach cancer
Also known as: Malignant neoplasms of stomach, unspecified
General information only. Anpheros does not diagnose and does not recommend treatment. Talk to a doctor or pharmacist about your situation. In an emergency, call 112 (or your local emergency number).
In short
The stomach is an organ between the esophagus and the small intestine that mixes food with stomach acid and helps digest protein. Stomach cancer mostly affects older people, and the risk of getting it is higher for men, cigarette smokers, those with a family history of stomach cancer, those who eat lots of salted, smoked, or pickled foods, or those who have had stomach inflammation or a Helicobacter pylori infection. Early stages are hard to diagnose and can present with indigestion and stomach discomfort, while advanced cases may involve blood in the stool, vomiting, unexplained weight loss, jaundice, or trouble swallowing. Doctors diagnose stomach cancer with a physical exam, blood and imaging tests, an endoscopy, and a biopsy, and treatment options include surgery, chemotherapy, radiation, or a combination.

Description
The stomach is an organ between the esophagus and the small intestine. It mixes food with stomach acid and helps digest protein. Stomach cancer mostly affects older people - two-thirds of people who have it are over age 65. Your risk of getting it is also higher if you:
- Have had a Helicobacter pylori infection
- Have had stomach inflammation
- Are a man
- Eat lots of salted, smoked, or pickled foods
- Smoke cigarettes
- Have a family history of stomach cancer
It is hard to diagnose stomach cancer in its early stages. Indigestion and stomach discomfort can be symptoms of early cancer, but other problems can cause the same symptoms. In advanced cases, there may be blood in your stool, vomiting, unexplained weight loss, jaundice, or trouble swallowing. Doctors diagnose stomach cancer with a physical exam, blood and imaging tests, an endoscopy, and a biopsy.
Because it is often found late, it can be hard to treat stomach cancer. Treatment options include surgery, chemotherapy, radiation or a combination.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
