Essential thrombocythemia (ET) is a rare, chronic blood cancer in which the bone marrow makes too many platelets.

How can ET symptoms affect daily life?

ET symptoms can include fatigue, headaches, dizziness, and circulation-related symptoms, and may affect day-to-day confidence and wellbeing.

Why is it important to talk to your doctor about ET?

Open conversations help your care team understand symptoms, discuss risks, and make informed long-term care decisions.
