FDA officials have telegraphed the decision for months. While the agency has long said that it did not think evidence of Red 3 causing cancer applied to humans, officials said their hand was forced by a law requiring the agency to pull additives that are cancerous in animals.

The U.S. on Wednesday banned the use of a synthetic food dye that gives some candies, cakes and certain oral medications a cherry-red color, following evidence that the dye causes cancer in laboratory rats.

"The FDA cannot authorize a food additive or color additive if it has been found to cause cancer in humans or animals. Evidence shows cancer in laboratory male rats exposed to high levels of FD&C Red No.

A fter announcing in March 2024 that she had been diagnosed with cancer, Kate Middleton, Princess of Wales, has again spoken out about her illness—this time, with good news. “It is a relief now to be in remission and I remain focused on recovery,” Middleton announced on X on Jan. 14.

The problem is that a complete remission does not mean the cancer is gone. Even when a cancer is “cured” — defined as no evidence of cancer for five years — it may not be vanquished.
