Not sure if this would be helpful, but I see an integrative oncologist in Vermont and very much appreciate the research-based information she has provided me to date. My adenocarcinoma is estrogen-receptive and I use transdermal estradiol cream to address atrophy. Hot flashes, mind fog and related sleep challenges were history for me by the time of my cancer diagnosis. I asked my integrative oncologist about her training and she recommended seeking someone certified by the American Board of Naturopathic Oncology. I looked on their list and found three in California, in San Luis Obispo, Thousand Oaks, Truckee, Santa Rosa one of whom is located in Palo Alto: Lena Suhaila http://www.NaturallyWellWithin.com. Here's the url for the overall list:

I wish you relief very soon!
