Can "bust-boom" (breast enlargement pills sold in amazon that do work) cause breast cancer? the ingredients include herbs working as phytoestrogens.

Breast Cancer: To my knowledge the only therapy that enlarges breasts is the brava which has to be used in conjunction with fat grafting. The use of unregulated herbs to enhance your breast has known be shown to work in any scientific way that I am aware of at this time.

Possibly: Anything with estrogen in it can increase your lifetime risk of developing breast cancer and higher levels can translate to higher rates. The levels of drung in over the counter "herbal" medications are often not controlled for or even measured. I would be wary.

Not FDA regulated: Any over the counter supplement sold as an herbal remedy does not have to be regulated by fda as normal medications do. Thus, while some ingredients may be listed others may not. While we do know increased estrogen exposure over ones life may stimulate breast cancer risk as well as cause other possible symptoms like benign fibroid tumors, i'd also b worried about what's not listed.
