Preparing for an appointment

- Write your three most important questions.
- Ask for plain-language explanations.
- Request copies of pathology, imaging and visit summaries.
- Confirm whom to call after hours.
How to judge online claims
- Is the author and medical review process clear?
- Are sources linked and dates shown?
- Does it promise a cure or tell you to stop standard care?
- Is someone selling the answer?
- Can your oncology team verify it?
Be cautious: “Natural” does not always mean safe. Supplements can interfere with treatment.
