This is something you need to think long and hard about and weigh up your pros and cons. Your medical team will insist you take them. You need to do as much research as possible (read only latest medical journals) and talk to as many medical professionals as possible, particularly about the things that most concern you.
For me, I tried tamoxifen and all aromatose inhibitors but side effects diminished my quality of life. I suffered vaginal atrophy, bloating and weight gain, digestive issues, lethargy, serious depression, painful bones and muscles, wild mood swings and quite frankly lunacy. Had I continued I would have certainly lost my husband and my family. I made the decision to instead, return to health and live as healthy a life as possible but live in fear of mastastises and have at times struggled with this decision but am at peace with it now. But, at the end of the day, if I do get secondary bc then how do I know I wouldn't have got it anyway? I have been cancer free for 3 years.
Some women are fortunate enough to have few side effects or over time their side effects diminish and would certainly encourage all women to try and persist with them first. You might be one of the lucky ones whose system can take them. Good luck...
