Polycythaemia vera (PV) is a slow-growing blood cancer where your body makes too many red blood cells. It's one of a group of blood cancers known as MPNs, or myeloproliferative neoplasms.

What is PV?

PV makes your blood thicker than than normal and raises your risk of developing blood clots, but treatment can lower this risk.

Finding out you have PV

Symptoms of PV

It's important to know about the effects of PV, but you won't have all the possible symptoms. You may not have any at all.

Tests for PV

You will need tests to diagnose PV, then to monitor the PV and help your doctor decide on the best treatment.

PV treatment and side effects

Treatment aims to control the number of red blood cells in your blood. If it causes side effects, your hospital team will help you manage them.
