These causes are rare and constitute about 1% of all causes of hypercalcemia of malignancy. [22] Hypercalcemia of malignancy usually portends a poor prognosis, and the medial survival is 25–52 days of its development. [22] It has an incidence of 30% in those with cancer, and the prevalence is estimated to be about 2-3% in the United States. [22]
