Cancell/Cantron/Protocel (PDQ®): Complementary and alternative medicine - Patient Information [NCI] - Overview

  • Cancell is a trademarked name of a liquid mixture long promoted as a treatment for people with cancer and other diseases (see Question 1).
  • The U.S. Food and Drug Administration (FDA) has listed the ingredients of Cancell as the chemicals inositol, nitric acid, sodium sulfite, potassium hydroxide, sulfuric acid, and catechol (see Question 3).
  • Cantron and Protocel are other products that are said to be similar to Cancell.
  • None of the common chemicals in these products is known to be effective in treating any type of cancer.
  • In the early 1990s, the National Cancer Institute (NCI) tested these ingredients against cancer cells in the laboratory and based on the results decided not to continue studying Cancell (see Question 5).
  • No clinical trials have been published in peer-reviewed journals. Only testimonials and anecdotal reports have been made available. (See Question 6.)
  • The U.S. Food and Drug Administration has not approved Cancell to treat cancer or any disease in the United States. In 1989, the FDA requested and received a court order making it illegal for manufacturers to send Cancell across state lines. (See Question 8.)
