Can bras cause cancer?

Bras do not cause breast cancer. Breast cancer happens when there's a problem with the way cells grow inside the body — and no one knows exactly why it happens. The chance of getting breast cancer increases as a woman gets older or if other women in the family have had breast cancer. Some things may protect a woman from getting breast cancer, including maintaining a healthy weight, being physically active, and breastfeeding her children.
