Risk factors
By Mayo Clinic staffSome factors may increase your risk of developing polycythemia vera:
- Age. According to the National Heart, Lung, and Blood Institute, polycythemia vera is more common in adults older than 60. It's rare in people younger than 20.
- Sex. Polycythemia vera affects men more often than women.
- Family history. In some cases, polycythemia vera appears to run in families, indicating that genetic factors other than JAK2 may contribute to the disease.
