Can breast cancer cause high calcium levels?

Hypercalcemia is a frequent complication of breast cancer which causes significant morbidity and mortality. Most commonly, it occurs in patients with multiple skeletal metastases. However, in a significant minority of patients, calcium levels become elevated in the absence of skeletal disease.

Why do cancer patients have hypercalcemia?

Hypercalcemia is most common in those who have later-stage malignancies and predicts a poor prognosis for those with it. The most common causes include humoral hypercalcemia of malignancy mediated by parathyroid hormone–related peptide, osteolytic cytokine production, and excess 1,25-dihydroxy vitamin D production.

Which malignancy is most commonly associated with hypercalcemia?

The most common cancers associated with hypercalcemia in the United States are breast, renal, and lung cancer and multiple myeloma [2]. Malignancy is usually evident clinically by the time it causes hypercalcemia, and patients with hypercalcemia of malignancy often have a poor prognosis.
