Can effective Breast Enlargement pills cause breast cancer?

FluffyPanda asked:


I started taking Bust-Boom recently. Less than a week and I already notice a huge difference in my Breast Size. They use phytoestrogens to increase estrogen to stimulate new breast cell growth. I’ve read that phytoestrogen may reduce the chance of breast cancer but I’ve also read that elevated levels of estrogen can encourage breast cancer cells. Does anyone know more about this? If you do, can you provide references?

Thanks
