NO!!!! You can not get breast cancer from sleeping with a bra on!! Do people actually believe that? If you do have questions about your breasts of any sort it#039;s in your breast interest to talk to a woman you can trust. Serioso!!!
I always wear my bra to bed since I was a teen, and my best friend susie who was 2 sizes bigger did not she would go home from school and take it off,...she got breast cancer I didn't if this helps or not i don't know,.but in my head it's a strain on your mams to just hang,...and bounce around freely...just me though...:)
