I had my post op appt today and was told that the tumour removed had clear margins and lymph node was clear too. So I will have five days of radiotherapy and have been prescribed Anastrozole. I have osteoporosis and have been taking biophosphates for three years. My consultant is aware of this. On reading the leaflet on Anastrozole it says it causes bone thinning. Is it safe for me to take or is there a different Hormone Therapy that would be more suitable. I have already had a fracture to my spine so don’t want to make my bones any worse.
