Stair-lift salesman sells animal dewormer and anti-scabies drug as cancer cures

An undercover journalist posing as a relative of a cancer patient bought fenbendazole and ivermectin from Jason Sarver, a stair-lift salesman in south Wales, after he claimed the drugs could shrink brain tumours and treat other cancers. Sarver sent the reporter links to popular videos that promote the unproven therapy and sold a two-to-three-month supply for roughly £100. One outlet discovered the same products were being sold on Amazon, which later took them down, citing its anti-prohibited-product measures.

Macmillan Cancer Support and Cancer Research UK stressed that neither drug has real-world clinical evidence for cancer treatment, and the MHRA warned that supplying prescription-only or veterinary medicines to humans breaches the Human Medicines Regulations. Senior oncologists warned the drugs could interfere with standard therapies, potentially harming patients who forgo proven treatment. The case highlights growing demand for dubious cancer cures and the regulatory challenges of online sales.
