Spontaneous remission or even disappearance of cancer DOES happen, regardless of what drs would have us believe. While we all wish it would happen a LOT more frequently, and TO US, we can still rejoice that your cancer is gone.
It sounds to me like the PremPro was feeding the cancer. When that ready source of estrogen disappeared, it probably weakened the cancer spots enough that your own immune system/cancer-fighting components was then able to wipe it out.
I would be careful about eating foods/taking supplements that have very powerful phytoestrogens e.g. soy. If you want to use flax seed or oil for it's health benefits, might be wise to really limit your intake - maybe no more than 1 - 2 tsp ground flax seed or 2 or 3 tsp flax oil a day, if even that much. (Still a lot of controversy among researchers as to whether soy and flax act as estrogen blockers or estrogen replacers. As long as there is no concensus and questionable one way or another, I think might just be safer to avoid them all together.)
Any of the herbal and food remedies for menopause should be approached with caution. Things like red clover flowers contain a lot of phytoestrogens, as do black cohosh and evening primrose. Yams and sweet potatoes are also very replete with phytoestrogens. The less supply you give your body, perhaps the less likely you will have a cancer situation arise again. You can do a web search for foods containing strong and weak estrogens - I would emphasize the weak estrogens in diet more than the strong estrogens, as it does seem that weak phytoestrogens will act as estrogen-receptor blockers while strong phytoestrogens will act as hormone replacement therapy.
Congrats on the good news!!! I wish you many years of happy wellness!!
Sincerely,
