Does wearing a bra increase my risk of breast cancer?

The claim

Wearing a bra might cause breast cancer.

The truth

There is no reliable scientific evidence that shows a link between wearing an underwire bra – or any other kind of bra – and developing breast cancer.

The Canadian Cancer Society is committed to sharing important information about cancer risk to Canadians and will continue to monitor research in this area.
