I also have been recommended biophosphates first-Fosamax or Reclasr. Only one year into Letrozole for ILC and he just did several labs and cleared me for Fosamax. With my Chrohns he was concerned I may to go right to Reclasr which is just so tough on your system. I’ve caved in and worth fractures will occur. I’m 58 and thin build and will start Fosamax tomorrow and I’m very anxious too!
