Tullio Simoncini (born 1951) is an Italian former physician and alternative medicine advocate. He holds a Ph.D. in philosophy from La Sapienza University. He is known for claiming that cancer is caused by the fungus Candida albicans, and has gone so far as to say that cancer is actually a form of candida overgrowth. He also says that cancer can be cured with injections of sodium bicarbonate. He says that he was formerly an oncologist, but that he was struck off because he prescribed sodium bicarbonate instead of conventional chemotherapy.
The mainstream medical community has rejected Simoncini's hypothesis, citing a lack of peer-reviewed studies that support its use. Quackwatch lists sodium bicarbonate injections as a "dubious treatment."
Simoncini was tried and found guilty of fraud and manslaughter in 2006 after a patient died after using Simoncini's treatment.
In 2012, Simoncini became involved in another controversy when he was invited to a conference in Totnes, England, by the Arcturus Clinic. Trading Standards then accused the clinic of violating the Cancer Act 1939 because they had published information that "offer[ed] to treat any person for cancer." Stephen Hopwood, the clinic's manager, described Simoncini's invitation as a "misunderstanding".
