Stomach (Gastric) Cancer

- Family history of stomach cancer
- Long-standing stomach inflammation (chronic gastritis)

Frequently asked questions
Is indigestion a sign of stomach cancer?
Usually not — indigestion is very common and mostly harmless. But if it is persistent, new in an older adult, or comes with weight loss or swallowing trouble, it should be assessed.
Can an ulcer bug cause cancer?
Long-term infection with Helicobacter pylori raises the risk of stomach cancer. It can be tested for and treated, which reduces that risk.
