I assume she meant whether to take an Aromatase Inhibitor or not. If you are ER+ and/or PR+ then this drug suppresses all hormones in your body, which were feeding your cancer. 40% of people have negative side effects from taking this pill. I have about 13 months left to take mine to hit my 5 year mark. My doctor talked about taking it for 10 years - but I discussed it at length with her and we decided I could stop at 5 years. I was on anastrozole for 12 months and suffered terrible joint pain - especially in my hands. I switched to Exemestane, which for me, has had less side effects. If you are pre-menopausal - they usually prescribe tamafoxin. Get all the information you need to make an informed decision on this. Good luck.
