Menopause treatment options as a breast cancer survivor?

I had estrogen positive breast cancer 11 years ago and had a double mastectomy then took tamoxifen for 10 years. Shortly after I had a total hysterectomy. Shortly after that and since (past 6 months) I have been suffering from extreme joint pain and stiffness. Gynecologist recommends HRT while Oncologist does not. I am scared to do anything to increase risk of breast cancer reoccurring but also scared of osteoporosis, heart disease, dementia and continued pain and suffering by not having estrogen in my body. I am 44 and would like to think I can still have a long and healthy life, but feel paralyzed as I can’t get a medical opinion that gives me confidence that I’m doing the right thing. Appreciate any advice you may have?
