High levels: Both your measured PTH and Calcium levels are high and this is likely because the breast cancer cells are producing too much PTH hormone which is making your body produce too much Calcium. You should discuss this in detail with your Oncologist to understand your treatment plan

Not related: Hi. I'm very sorry about your cancer. I hope treatment is going very well. Breast cancer can make a "hormone" related to PTH, but it cannot make PTH. The PTH-like cancer hormone causes hi blood calcium. Your low-normal calcium with hi PTH is called secondary hyperparathyroidism. Your PTH is hi to PROTECT you from LOW blood calcium. Causes: GI malabsorption, vit. D deficiency, kidney calcium leak.
