Interesting that they don’t talk about all the side effects of the drug. Shutting off all estrogen receptors is not needed. Indole 3 Carbinol, Diindolylmethane or Sulforaphane glucosinolate all made from broccoli and cruciferous vegetables can do a much better job than these pharma drugs at blocking the ‘bad’ estrogen and letting the ‘good’ estrogen stay. And...no side effects.... But then again, they cost about 1/4 less than the pharma drugs... ;)
My wife took aromatase inhibitors (Femara for 3 months, then Aromasin for about 5 months) after she completed her primary treatment - “lumpectomy”, two courses of dose-dense chemo, and radiation. But she had to switch to Tamoxifen because she was experiencing severe and worsening leg pains. We are nearing 4 years since her surgery with no recurrence, but she is approaching the time when the benefits of Tamoxifen begins to decline. Statistically, she would benefit from returning to an aromatase inhibitor IF she can tolerate it.
