I had lymphoma and after chemo I had low level radiation to my chest. Most women have a 15% chance of breast cancer but I have a 19% risk.  It wasn't too bad because I was already in remission by the time I had radiation; it was more of an insurance policy. 

The odd thing is that any hormonal issues I had before cancer (irregular periods and slightly hairier than I would have liked) completely disappeared afterward.  I took an injectable medication called Lupron to preserve my fertility and wonder if that did anything.

I am very interested in NBE and have purchased a Noogleberry. I also ordered PM and other things from Chiyomilk's regimen. Other than collagen, pig's placenta and "skin hair and nails" supplements to take daily, I will be using progesterone cream and fenugreek during the luteal phase and PM during the rest of the cycle. I will also massage and am considering getting gluteboost.

On the one hand, I am a little bit paranoid about growing breast tissue, but on the other I know that breast implants make mammography difficult.  The other option would be to do nothing, but after cancer I think I deserve to feel good about my body.

Has anyone done any research about the risks of NBE and breast cancer?

Edit: I had my hormones tested pre-chemo and they were fine despite the irregular periods.  I just realized the Lupron releases a bunch of estrogen so maybe estrogen was good for me.

Estrogens are well known to increase breast cancer risk in some women, however, for example, OCP (oral contraceptive pills) have estrogens and may increase the risk only slightly. OCPs are also known to decrease the risk of ovarian cancer. Phytoestrogens in the other hand, have been measured in urine of women in women with lower prevalence of breast cancer, like Japanese women and had been found in higher levels. In animal studies, phytoestrogens were found to interfere with tumor formation in rats.

In general you should be cautious and limit your consumption, because some phytoestrogens can have a estrogen like effect, and those could potentially cause cancer.
