HRT (Estrogen and Progesterone Hormone Replacement Therapy) After cancer for menopause?

I have three to five hot flushes during the night, every night. Plus numerous during the day. I also have menopause induced issues with my lady bits. Yesterday, my mets nurse put me on to "The Womens Menopause Symptoms After Cancer Clinic" held at the Royal Womens Hospital. I believe there are similar clinics in other states. I need to get a referral and then book in. They have Gynos, Oncos, Endos, Psychs, Sexual Counsellors and specialist nurses in their multidisciplinary team. I am booking in with my GP today to get that referral!
