I have done my research but this may be a stupid question but is an avm a tumor?
Thank you
Leandra
No. Tumors tend to be nodule lesions (aka hard ones). AVMs are soft & not cancer adjacent; they are vascular defects that are congenitally rooted affecting the circulatory system.
Eli is right. An AVM is a malformation of arteries and veins. It is more difficult to remove than a tumor.
A brain AVM (arteriovenous malformation) is an abnormal connection between arteries and veins. An AVM is usually congenital, meaning it dates to birth.
