👉 The term "chondroangioma" refers to a type of tumor that occurs in the blood vessels, specifically the arteries and veins. These tumors can grow out of control or become malignant, which means they have the potential to spread and cause serious health problems. Chondroangiomas are typically benign (not cancerous) but not completely harmless either. They often appear as small, hard, red bumps that form on the skin or in the bones. The exact cause is not fully understood
