Polycythemia vera

Overview

Polycythemia vera is a chronic, slow-growing cancer. Bone marrow makes too many red blood cells, and sometimes white blood cells and platelets, too. The excess cells can cause blood clots or bleeding. It may develop over years and is often found by chance in a blood test.

Treatments

Treatments include drugs and drawing blood to reduce its thickness.
