What does "non-invasive tumor" mean?
James Metz, MD, OncoLink Editor In Chief, responds:
A 'non-invasive' tumor really means that the tumor has not invaded through layers of the organ. However, non-invasive, does not necessarily mean a tumor cannot cause a problem. 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.
