My mom says that if you sleep with a bra on, it is really bad for you and it might cause breast cancer. Is that true?

According to the American Cancer Society, there is "no scientific or clinical basis" to an Internet rumor that claims that under-wire bras cause breast cancer. So tell your mom that there is no proof that wearing a bra night or day has any link to cancer.
Are you having pain in your breasts? Painful breasts are often caused by normal hormonal shifts; many girls feel particularly tender right around the time of their period. But if the pain is consistent, or your back is hurting, mention it to your doctor and ask what might be causing your discomfort.
Are you wearing a bra a night because you feel uncomfortable by your developing breasts? Sometimes it seems like they'll never stop growing, or you may feel like they're not the "right" (whatever that means) shape and size. It's stressful when your body goes through such rapid changes or growth spurts. Just remember, no matter how much you think you look weird or different, everyone else goes through similar moments of anxiety and total body trauma.
