What does science say about Zinc and cancer (all types)?
- We don’t say yes or no. We show what has been studied.
- Working in a lab or in animals does not mean it works in people.
- Don’t stop or change your treatment without talking to your doctor.

Thinking of paying for it? Read this first
- Ask for published results. Stories, thank-you letters and "patients report" are not results. Ask where the results were published.
- Know what you pay for. Ask in writing: what exactly is included, who gets the money, and what happens if you stop.
- Ask your own doctor first. Some products interfere with chemotherapy, radiation or other medicines. Your treating doctor can check this.
- Do not stop standard treatment for it. Do not stop or delay your treatment without talking to your care team.
Not medical advice. Talk to the care team before changing treatment.
