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.
