Hi Celeste,
My Bc was the same as yours - Hormone receptive but I didn't have chemo only radiation after surgery. I chose not to have chemo even though my oncologist would have preferred it. I figured that there wasn't enough "add on" over a 10 year period to warrant being sick for 6 months. I was 50 when I was diagnosed and was premenopausal. I am now 54 and have been on Tamoxifen for 3.5 years. Just when I think I am getting near menopause, I have another bleed. The longest time was 9 months. They say if you go without a period for 12 months then you have reached menopause. My dear departed mum was 56 when she finally stopped. I have had a hormone test and it showed that I haven't reached menopause yet. Bugger still some little hormones lurking about. I was told that I would be taking Tamoxifen for 5 years and then it would be reviewed. You are right in saying that Arimidex is for after menopause however I have also been told that Tamoxifen can be taking for a further 5 years even if you have gone through menopause. Personally I have had no trouble with Tamoxifen except for some bleeding which my gyne checks out with surgery (remember this drug carries a high risk of uterine cancer) I have heard lots of bad reports about Arimidex - it leeches the bones of calcium. Not happy with that. Anyway talk with your oncologist but if you are not having too many side effects with Tamoxifen then it's for you.XLeonie
