Can benign tumors ever become malignant? How often does this occur? I have osteochondroma on my right knee. It is painful at the moment when I walk.
Usually no: Osteochondroma, also called exostosis is the most common benign bone tumor. Slow growing, painful if impinges on nerve or stalk is broken; usually stops growing and ossifies at puberty.
