BPA and Cancer Risk: What the Science Tells Us

Wednesday, October 19, 2022

BPA has for too long been incorrectly identified as the cause of several health effects, among them cancer. But there simply is no evidence to back up the notion that using products containing BPA raises the risk of cancer. In fact, numerous scientific studies have found no link between BPA and cancer, making this one of the biggest urban myths surrounding BPA.

The CLARITY Core Study, a two year guideline-compliant study on the toxicity of BPA in rodents conducted by the FDA, thoroughly examined potential long-term health effects. The CLARITY Core Study researchers exposed laboratory rodents to BPA over their lifetimes, including pregnant rats and their offspring. What’s more, an expert panel from National Toxicology Program (NTP) put the CLARITY Core Study through a rigorous peer review to ensure that the results and conclusions were presented fully and clearly. The peer review panel supported the CLARITY Core Study’s bottom-line conclusion: BPA has little potential to cause health effects, including cancer.

Furthermore, while some critics have suggested that BPA could be an “endocrine disruptor,” meaning it could spark hormonal changes that can cause adverse health effects, the CLARITY Core Study results do not support this conclusion either.

The science is clear: Using plastic products made from BPA does not raise the risk of cancer. Smoking? Spending hours in the sun without sunscreen? Yes, those behaviors have been scientifically linked to an increased risk of cancer. Plastics containing trace amounts of BPA? Don’t worry.
