Last year, we came together to correct a critical misconception that desmoid tumors are NOT benign. This year, we are building on that momentum to go one step further and make sure the correct classification of desmoid tumors is front and center.
The medical community, research publications, and other sources often use differing terms when describing desmoid tumors. This confusion can lead to misunderstandings about treatment and minimizes the potentially serious consequences of this rare disease.
How are desmoid tumors classified?
Desmoid tumors (also known as aggressive fibromatosis, desmoid fibromatosis, and desmoid-type fibromatosis) do not metastasize. They are classified by the World Health Organization (WHO) as “Intermediate (locally aggressive)” soft tissue tumors. They do not fall under “Benign” or “Malignant” classifications.
Learn more about the World Health Organization’s (WHO) classification of desmoid tumors, which is listed under Table II: Fibroblastic/Myofibroblastic Tumours.
