How common is EHE?

Epithelioid hemangioendothelioma is exceptionally rare. Less than 1 in 1 million people get this type of tumor. It’s more common in people aged 20 to 60, but children, teens and people older than 60 can also get EHE. EHE is slightly more common in people assigned female at birth, but researchers aren’t sure why.
