Hi, Kris,
I had radiation after surgery, no chemo. I had two periods 2 weeks apart right after surgery, one normal during radiation, but nothing after, which makes it 3 months. Haven't really thought about it, other than thinking it's the stress. On the other hand I just turned 50, so it's getting to be the time anyway. May be the time to look for books on menopause, I understand the Silent Passage is still valid.
I know I don't want to try any kind of hormones, if I can avoid it. Now i am starting to wonder if certain of the miseries I'm blaming on radiation could be menopause instead. Somehow I've been thinking ,well, my mouth is dry, so why not other places, too. I know thrush spread to my vagina when I had it in my mouth, although it did not hurt nearly as much as in the mouth. I know, it has nothing to do with menopause, just babbling.
I am not surprised they did not mention menopause as a side effect to you. So many unpleasant things they "forget" to tell us about, I guess afraid to scare us, but I would rather know ahead of time and not be even more scared when something happens - or doesn't happen, like a period.
