Risk factorsBy Mayo Clinic staff
Factors that may increase your risk of developing polycythemia vera include:
- Increasing age. The risk of polycythemia vera increases with age. It is more common in adults older than 60, and it's rare in people younger than 20.
- Being male. Polycythemia vera affects men more often than women.
- Having a family history of polycythemia vera. Having close relatives with polycythemia vera may increase your risk of the disease.
