UNDERSTANDING STOMACH CANCER
What to know
This page provides a starting point for learning about stomach cancer. Cancer types and individual experiences vary, and information here is not a substitute for personalized medical guidance.
Possible signs
Possible symptoms include indigestion, stomach discomfort, feeling full quickly, nausea, appetite loss, or unexplained weight loss. These symptoms are common and often have non-cancer causes.
- Keep track of changes that are new, persistent, or unusual for you.
- Symptoms can have many causes and do not necessarily mean cancer.
Risk factors
Risk factors can include Helicobacter pylori infection, smoking, some dietary patterns, family history, and certain inherited conditions.
- Having a risk factor does not mean a person will develop cancer.
- Share relevant personal and family history with a healthcare professional.
When to seek guidance
Discuss persistent symptoms or relevant family history with a clinician. Testing and follow-up depend on symptoms and individual risk.
- Ask about tests, screening, or follow-up appropriate to your age and personal risk.
- Seek urgent care for severe or rapidly worsening symptoms.
