I was told that at my age, 84, that I wouldn't have many side effects other than some hand stiffness and aches and pains along with hair thinning. I think it might be that Dr.'s don't want to put pretreatment thoughts in our minds to imagine things. Some people do cruise through without any symptoms of side effects. I know of a couple. Wonder why or how. At my last visit the oncologist asked if I thought I could stay the course of treatment. I told her yes, as of that moment on that day. I am trying, but will see how severe these side effects turn out to be. I am on Exemestane now for 4 months. Had to stop the Anastrozole after 3 months.
