question: Hi doctor, Five years ago, I had a hysterectomy for early stage node negative breast cancer. I am 49 years old. Currently, I am on Arimidex. My prognosis was 4% risk of recurrence. Since my surgery, my calcium levels are at 9.7 to 10.2 and albumin are 4.7-5.0. Four years ago, a routine CT scan showed two stones. I have them followed annually by ultrasound. This month, my doctor decided to do a 24-hour urine as the stone grew a little. I have attached the reports. My 24-hour urine was 452, which I understand is elevated. Is the level very high? Does lack of estrogen raise calcium in urine and affect urine results? I did have one lobe of my thyroid removed before 16 years for 4 mm papillary thyroid cancer. My PTH was checked three years before and it was 22.
