Does heating food in plastic containers in the microwave cause cancer?

Summary

Scientists haven't found direct proof that microwaving food in plastic containers causes cancer, but this review of existing research found some concerning clues: heating plastic can cause chemicals and tiny plastic particles (microplastics) to leach into your food. We don't yet know exactly how risky this is, so more studies are needed—but until then, using glass or ceramic containers for microwaving is a simple, low-risk precaution.
