Who Is At Risk for Thrombocythemia or Thrombocytosis?
This condition isn’t common. The exact number of people who have the condition isn’t known. Some estimates suggest that 1 to 2.5 out of every 100,000 people have primary thrombocythemia. This number may be low, because most people who have the condition don’t have symptoms. Therefore, they may not know they have it. Primary thrombocythemia occurs mostly between the ages of 50 and 70, but it can occur at any age. For unknown reasons, a higher number of women around the age of 30 have primary thrombocythemia than men of the same age.
