A.
To evaluate: The serum calcium level in blood of patient having a breast cancer history.
Introduction: Calcium balance in the body is maintained by parathyroid hormone, thyrocalcitonin hormone of the thyroid gland, and vitamin D. Parathyroid hormone and possibly vitamin D stimulate Ca++ reabsorption in this segment of the nephron. In contrast, thyrocalcitonin helps in lowering the levels of calcium and phosphate in the blood.
B.
To describe: The significance of the recent history of malignancy in patient having hypercalcemia.
Introduction: Several malignant tumors, including carcinoma of the lung, breast cancer, have been associated with hypercalcemia. Hypercalcemia of malignancy is particularly common in cases of advanced-stage cancer.
C.
To determine: The tests which indicate the patient’s condition.
Introduction: The detection of hypercalcemia in a patient with cancer signifies poor prognosis, primarily because the presence of hypercalcemia usually indicates skeletal metastasis.
