How realiable are studies that claim using a bra more then 12 hours a time increases the risk of breast cancer?

There are several studies that claim this, but it seems they are not medically recognised and I'm not sure they consider other factor about their theory test subjects. On the other hand some relations recommend using a bra 24 hours a day to facilitate with cysts. So who should we girls listen to?

Not sure, in attendance is no solid proof, yet. Most of the studies I've see, seem to be pointing to women that are wearing a bra to be precise to small, or is otherwise squeezing, or putting too much pressure on your breasts, like some push-up styles do. The hypothesis is that, over time, all that extra pressure damages the breast tissue and leaves it vunerable. Since the tissue is undermined, it cannot fight rotten the cancer as well as a healty breast could.

Do I beleive that wearing a bra will result in cancer, NO. However I did get rid of some of my tight-fitting ones, and decrease the amount of time I spend in a push-up. Better out of danger than sorry!!
