How to Report Cancer Fraud and Pursue a Claim

If you, or someone you love, paid for a cancer “cure” that was never going to work: where to report it in Canada and the United States, what to keep, how to try to get money back, and where to find legal help you can afford.

Health first. If someone is still being treated, the most important call is to their own doctor or oncologist — today, not after the complaint is filed. Bring the products and the paperwork with you; some “natural” cancer products interact with real treatment or cause harm on their own. If someone is in immediate danger, call 911.

What to keep Reporting in Canada Reporting in the U.S. Clinics in Mexico Getting money back Free and low-cost legal help

Before anything else: write it down and keep everything

Every route below works better with paper. Gather it now, while memories and websites still exist.

Report, don’t accuse in public. However angry you are, put the facts in front of the bodies below rather than on social media. A complaint to a regulator is protected in a way a public accusation is not, and a factual complaint is far more likely to be acted on than an angry one.

Reporting in Canada

File with more than one body, and say in each complaint that you have done so — agencies whose jurisdictions overlap otherwise point at each other.

Competition Bureau Strongest for false claims

For advertising that claims a product or service treats or cures cancer. Under the Competition Act the seller, not you, must show the claim was properly tested before it was made. You don’t need to have lost money to complain.

Online complaint form at competition-bureau.canada.ca (Contact us › Complaint form) · 1-800-348-5358 (toll-free) · TTY 1-866-694-8389

Health Canada For the product itself

For pills, drops, injections, supplements or devices sold without authorization, or advertised for cancer. Use the right form: the Health Product Complaint Form for drugs and natural health products, and the separate Consumer Medical Device Report Form for machines and devices. Say in the first line what kind of product it is.

If a product caused a side effect or injury, also report it to Canada Vigilance: 1-866-234-2345.

Your local police Where money was taken or someone was harmed

Fraud is a Criminal Code offence. Ask for a report number. Police may refer the file elsewhere, but a report on record matters if others come forward later.

Canadian Anti-Fraud Centre Records, does not investigate

Run jointly by the OPP, the RCMP and the Competition Bureau. It doesn’t investigate individual cases, but reports are shared with police and the Bureau, and patterns across many reports are how files get opened.

The practitioner’s regulatory college If they are a regulated professional

Physicians, naturopaths, chiropractors, nurses, pharmacists and others are regulated by a provincial college, which can investigate and discipline. In Ontario, for example, the College of Physicians and Surgeons of Ontario and the College of Naturopaths of Ontario take complaints from anyone — you don’t have to have been the patient.

If the person belongs to no regulated profession, there is no college to complain to. Use the Competition Bureau, Health Canada and the police. In Quebec, the Collège des médecins itself prosecutes the illegal practice of medicine in court, and has obtained fines as high as $120,000 against an unlicensed practitioner.

Your Member of Parliament

Not a complaint route, but a letter from your MP to the federal Minister of Health on your behalf gets a more considered written answer than a letter from you alone.

More detail on the federal routes, with the strategy behind them, is in How to complain, and to whom.

Reporting in the United States

Federal Trade Commission For false advertising

For cancer-cure claims in ads, websites, infomercials and social media. Most of the cases on our prosecutions page that ended in refunds began with the FTC.

ReportFraud.ftc.gov

Food and Drug Administration For unapproved drugs and devices

To report a website selling an unapproved drug, supplement or device, use the FDA’s online form “Reporting Unlawful Sales of Medical Products on the Internet.” If a product caused harm, report it to MedWatch, the FDA’s safety reporting program.

fda.gov › Safety › Report a Problem · urgent problems with a product bought online: 1-866-300-4374

Your state attorney general Consumer protection

State attorneys general have shut down cancer-cure websites and won refunds and penalties. Every state has a consumer-protection complaint form; the National Association of Attorneys General (naag.org) lists them all.

Police or district attorney Unlicensed practice, theft, harm

Practising medicine without a licence is a state crime. Several cases on our prosecutions page were brought by county prosecutors or a city attorney — one of them after a widow took her husband’s story to the sheriff.

State licensing boards

For licensed physicians, nurses, naturopaths and chiropractors. The Federation of State Medical Boards (fsmb.org) links to every state medical board.

Clinics in Mexico and other countries

Many cancer clinics that recruit Canadians and Americans operate in Tijuana and elsewhere in Mexico, often booked through a U.S. or Canadian office. Report the office and the advertising at home — to the Competition Bureau or the FTC — because that is where your regulators have reach. Also file at econsumer.gov, which shares cross-border complaints with consumer-protection agencies in dozens of countries, including Canada and the U.S. Mexico’s health regulator, COFEPRIS, accepts complaints about clinics directly.

Trying to get your money back

Deadlines are short. In Ontario most civil claims must be started within two years of when you knew, or should have known, about the claim. U.S. deadlines vary by state and are often one to three years. Don’t wait for a criminal case to finish before getting advice on a civil one.

Your credit card or bank

If you paid by credit card, ask the card issuer about a chargeback for services not as represented. Card issuers set their own time limits, often a matter of months, so act quickly.

Small claims court

Designed for people without lawyers. In Ontario the limit rose to $50,000 on October 1, 2025. Other provinces and U.S. states set their own limits. A judgment is only as good as the seller’s ability to pay, so ask about collection before you start.

Refunds from government cases

When the FTC or the Competition Bureau settles a case, it sometimes requires refunds to buyers. The FTC lists active refund programs at ftc.gov/refunds. If you bought from a seller named in a case, contact the agency even if you never complained.

When someone was seriously harmed or died

Where a patient gave up effective treatment, was injured, or died, the claim may be for far more than the price paid. Personal-injury and wrongful-death lawyers often take such cases on contingency — paid from what they recover, not up front. The free consultation services below can point you to one. In one U.S. case on our prosecutions page, a jury awarded a breast-cancer patient $105 million against the man who treated her with baking-soda infusions; in another, a New York jury found a doctor liable for treating uterine cancer with coffee enemas and enzymes.

If you have reported a cancer “cure” to any of the bodies above, we would like to know what happened — including if nothing did.
