Dr. Rapoport on Hyponatremia in Patients With Cancer

Frederick Alan Rapoport, MD, clinical instructor in the Department of Medicine at NYU Langone Medical Center, discusses hyponatremia in patients with cancer.

Hyponatremia is a common manifestation of many cancers, especially in small cell lung cancer. Rapoport says that head and neck cancer, ovarian cancers, and some hematologic malignancies can also present with hyponatremia.

In addition, hyponatremia is a complication of states that can be associated with malignancies, such as dehydration, nausea, vomiting, or pain. Rapoport says hyponatremia can also be associated with some cancer drugs.
