If it were estrogen deficiency, wouldn't taking phytoestrogens help the cysts be less painful or slowly go away? taking any phytoestrogens orally or transdermally makes them more tender and swollen. Stopping them makes them go back down, but not permanently.

edit: taking the phytoestrogens (even just one dose) makes the cysts (only present in the right breast) tender and swollen, not the breasts themselves.
