The pros all point out that it’s imperative that tests be run on actual humans before they can make definitive conclusions about cancer risk. However, this is a time-consuming study, because cancer development doesn’t happen overnight. “It oftentimes happens after 5, 10, 15 years of exposure, so the study results may be a decade or even two away from being really clearly correlated for us,” says Dr. Karam. Do with this information what you may, but, ultimately, it’s a personal decision about whether or not you want to stop all together to eliminate any potential exposure and risk.
