Anyone got any thoughts on whether the change from Tamoxifen to an aromatase inhibitor is the right thing to do? I have been taking Tamoxifen for 5 years and as I am now past the menapause, my oncologist has given me the option of changing from Tamoxifen onto an AH. I don't like being given the choice, I'd rather be told what to do! I have coped well in recent years with Tamoxifen, but I think that there is a better outlook for the future on an AH. I am now 54 and was diagnosed is 2010. It may be a case of 'better the devil you know!'
