hypercalcemia of malignancy
"After breast cancer I had to go on Prolia to counter act the possible fractures caused by my cancer meds. My PCD noticed my PTH levels were off the charts and sent me for  a CT scan.
My numbers went down after 5 months post Prolia. They went up pre 2nd shot of Prolia. I went to Mayo Clinic because I needed an answer. The endocrinologists there stated point blank that the high PTH is common with Prolia, but that Prolia outways the possibile fractures weak bones can cause. So I'm damned if I do, damned if I don't. He told me to up my Calcium and take 1000 units of Vitamin D /daily."
