I was diagnosed with breast cancer 5 years ago this week. My oncologist insisted I do either Prolia or Reclast infusions. I've had 7 infusions and thankfully no side effects. My osteoporosis reverted back to osteopenia. As a former RN, I was very reluctant to have either Prolia or Reclast. Was very concerned about side effects...if you have any, what then? The drug is in your body and there's nothing to be done about it. But, I knew I had to take the risk. I'm done with Anastrozole next month and my osteoporosis specialist said no more Reclast, unless I would need to go back on an AI. I'm going to celebrate...Anastrozole has been the worst part of my treatment...so many side effects that have impacted my quality of life. Anyway...good luck to you. Stay strong!
