Hi, I understand night sweats and menapause will cause this. My own intuition tells me your body is going thru many chemical changes, thru the chemo. It could be menopause, but it may just be the stress etc. Ride it out and give it some time. I was told I needed to be without a cycle for a very long time before menapause was declared the problem. Best of luck to you, and know you are in my prayers. Very sincerely yours, CArol
