There was no link between wearing bras regardless of type, duration, or tightness and an increased risk of breast cancer. 

Dr. Lu Chen, the lead author of the study, concluded: “Our study found no evidence that wearing a bra increases breast cancer risk among postmenopausal women.”

The American Cancer Society: “There is no scientifically valid study that shows wearing bras of any type causes breast cancer.” 

The National Cancer Institute and the Cancer Council of Australia echo the same: No link. No risk. No evidence.
