Tumor Lysis Syndrome

Medically reviewed by Last updated on May 6, 2024.

What is tumor lysis syndrome?

Tumor lysis syndrome (TLS) is a condition that happens when cancer cells die quickly. Dying cells release large amounts of potassium, phosphate, and uric acid into the blood. This can cause heart or kidney problems and lead to kidney failure. TLS can become life-threatening if is not managed or treated. It most commonly happens after chemotherapy or radiation treatment, but may also occur after other forms of cancer treatment.
