Hi @nicnac17 here is a long thread discussing exactly what you’re asking. There are arguments for and against. It is quite long but you can give it a go and see if it’s worth getting to the end. Just click the pink header.
I think @balchik is right - the decision on whether to take it can be very different depending on your age. Older women tend to take their chances. Two other quick points - 1. The people who tolerate endocrine treatment well (and there are many) tend not to come back to the forum but just get on with life, so you’ll see a disproportionate amount of posts from those who don’t tolerate it well and 2. You have nothing to lose by trying and giving it six months to see how you get on. The side effects, if you have them, dissipate quickly once you stop the drug. Finally you have to determine how risk averse you are because, if you were to get a distant recurrence, treatment tends to be much harsher. Having said that, it is estimated that 30% decline to take it or give it up so you would not be alone.
