What does "non-invasive tumor" mean?
James Metz, MD, OncoLink Editor In Chief, responds:

Like real estate, it is all about location. A non-invasive tumor in the brain can push on critical structures and make it act in a malignant fashion. It is important to look at the entire situation to determine there are any additional treatments required.
