Hi Louisa, Glad to hear you sounding much better today. With HRT, you are basically replacing what your body does not produce naturally on its own anymore. There are some hormone receptive cancer patients that can not use HRT, but in my case for cancer of the cervix being non hormone related the risks for me are nearly zero as far as developing other cancers like breast I am actually better off using HRT than without. There is so much info out there you have to be careful to relate the info to what is correct for your own situation. When I asked my onco what he thought of a natural based therapy he said it would be fine if I was a 'plant', which I thought was funny. I stopped using the HRT for about 6 weeks and told him about it, he said get straight back on or you triple your risks for heart and bone disease. I am so lucky that I have a really great doctor. I totally trust his advice and know he wants me to live a long healthy life so thats the direction Ive always headed in. But i always do my own research and his info is always backed up by scientific fact. Having said all that it really is just down to personal choice. I know that I went into menopause literally overnight due to my ovaries being zapped by the radiation, the discomfort from the symptoms were quite horrendous for me prob due to my age, I could not imagine being able to function without the HRT now. Why dont you just wait and see what happens. they should do a blood test to check your hormones when your treatments are finished or before if need be, then you can make a decision based on how you're feeling.
