Hi Kaz D
from me too
I don't have any experience of this injection either, but ovary removal does sound like a drastic step especially at your age, as you are probably pretty near actual natural menopause. You may find that after surgical menopause the shock to your body is so great that the hot flushes and dip in mood become unbearable without HRT.
Also having aunts with breast cancer does not necessarily preclude you from having HRT - unless you definitely have the gene concerned ie have been tested for it, and are therefore at risk. It seems to me that a course of transdermal HRT would be preferable to surgery if you can - but of course I am not you, and do not have your problems. I'm afraid that natural supplements won't actually help in the same way - although of course for those who have actaully had breast cancer, this is their only option.
Do have a read about HRT from the menus at the top and ask us anything specific and we will try to help!
I am sure others will be along with advice too!
