Heat Food in Glass, Not Plastic: Oncologists Warn of Cancer Risk
Oncologists warn that microwaving food in plastic can cause chemical leaching (including BPA, phthalates, styrene, and PFAS) that may disrupt hormones and contribute to cancer risk. While the exact level of risk is still being studied, reducing exposure—by heating in glass or ceramic, using microwave-safe lids or parchment, avoiding reheating takeout containers, and storing leftovers in glass or stainless steel—can lower potential harm as researchers learn more.
