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).
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.)
