In September 2008, the Federal Trade Commission launched "Cure-ious?", a website that helps consumers see through bogus cancer 'cures' offered on TV, the web, and elsewhere. The website can be found at www.ftc.gov/curious, and the following content, in the public domain, comes directly from that site.
All cancers are different. Even two people with the same diagnosis may need different treatments. That’s one reason it’s best to be skeptical of websites with ads for products that claim to treat cancer.
Scammers take advantage of the feelings that can accompany a diagnosis of cancer. They promote unproven – and potentially dangerous – remedies like black salve, essiac tea, or laetrile with claims that the products are both “natural” and effective. But “natural” doesn’t mean either safe or effective when it comes to using these treatments for cancer. In fact, a product that is labeled “natural,” can be more than ineffective: it can be downright harmful.
For example, testimonials in ads can seem honest and heart-felt, but they can be completely fake: in fact, they may not disclose that actors or models have been paid to endorse the product. Even when testimonials come from people who have taken the product, personal stories aren’t reliable evidence of effectiveness.
Big words from a medical dictionary are no substitute for the plain facts from your doctor.
Even if the guarantee that you’re promised is legitimate, a money-back guarantee definitely is not a reliable substitute for scientific evidence that a treatment is safe or effective.
