Does small cell lung cancer cause hypercalcemia?

[1] Hypercalcemia is usually associated with advanced malignancy and is a poor prognostic sign. [1] Hypercalcemia is a very unusual complication of small cell lung cancer (SCLC) even in the presence of bone metastases.

Can lung cancer cause high calcium?

Cancers that more commonly cause high calcium levels in your blood include: Lung cancer. Head and neck cancers. Multiple myeloma.

Does high calcium in blood mean cancer?

High levels of calcium in blood, a condition known as hypercalcemia, may be an early indication of certain types of cancer, according to a study by researchers from the Universities of Bristol and Exeter.

Why do you get hypercalcemia with cancer?

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.

What is humoral hypercalcemia of malignancy?

Humoral hypercalcemia of malignancy (HHM) is caused by the oversecretion of parathyroid hormone-related peptide (PTHrP) from malignant tumors. Although any tumor may cause HHM, that induced by intrahepatic cholangiocarcinoma (ICC) or gastric cancer (GC) is rare.

Can lung cancer cause high potassium?

Hyperkalemia most often is caused by potassium retention due to renal insufficiency. A rare cause of hyperkalemia is adrenal insufficiency induced by adrenal metastasis. The latter is found in metastatic lung cancer in up to 40 to 60 percent, however in the majority of patients without clinical significance.

Should cancer patients take calcium?

The results of some studies suggest that a high calcium intake may decrease the risk of one or more types of cancer, whereas other studies suggest that a high calcium intake may actually increase the risk of prostate cancer.

Can you have hypercalcemia without cancer?

Hypercalcemia is caused by: Overactive parathyroid glands (hyperparathyroidism). This most common cause of hypercalcemia can stem from a small, noncancerous (benign) tumor or enlargement of one or more of the four parathyroid glands.
