I have always heard that sleeping with a bra on can cause breast cancer, is this true?

No: It is not true that sleeping with a bra on causes breast cancer. It's good for your breasts to have good circulation, like all parts of your body, so wear a bra that fits well and does not bind you anywhere.
Dr. Hung Khong
Medical Oncology 27 years experience
No: There has been no scientific evidence that sleeping with a bra on causes cancer of any kind, including breast cancer.

Absolutely not: Whether you wear a bra all the time, or none of the time, or anything in between - has nothing tyo do with developing breast cancer.
Dr. Keith Stockerl-Goldstein

Not true: Sleeping with a bra on will not cause breast cancer.

Can weraing a bra all the time cause breast cancer?

No: A book called “dressed to kill” indicated underwire bras restricted lymphatic drainage & led to accumulation of toxins in the breast. It was theorized this contributed to development of breast cancer. However, lymphatic drainage from the breast is not downward (gravity) – it moves towards the axilla (arm pit). The author's conclusions were not based on medical science & are not deemed accurate.

Does wearing padded bras cause breast cancer?

Dr. Gurmukh Singh
Pathology 49 years experience
Unlikely: There is objective evidence that wearing bra or a padded bra has anything to do with breast cancer. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form. Practice safe sex. Get HPV vaccine.
