What is the difference between a brain lesion and a brain

This answer was rated:

What is the difference between a brain lesion and a brain tumor? Are these terms interchangeable? I have heard both terms used in conjunction with my father's brain mets from stage IV NSCLC.


Brain lesion is any pathology of the brain - it could be a tumour, a blood clot , a cyst, an aneurysm, an inflammatory mass, any pathology.

A brain tumour is a specific pathology. All brain tumours can also be called brain lesions, but all lesions are not tumours.

I hope this helps.
