There is actually nothing to do to prevent breast cancer. Only if there is a genetic predisposition, if there is a BRCA positive, which we call BRCA positive in genetic screening, maybe breast surgery can be performed before cancer. But apart from that, there is nothing we know at the moment that I should do this or that to get breast cancer. But we know that as the weight, that is, the fat ratio in the body increases, the estrogen hormone will increase, so there may be a predisposition to breast cancer. Considering this, it can be done as follows. Sports, exercise and regular nutrition. With these, maybe we can stay away to some extent.
