Question

What is brain nodules?

Answer 1

Nodule literally means "a little knot or k**b."

In medicine a nodule is a collection of cells that forms a roughly circular structure.  Most of them are small ranging in size from about 1 to 2 cm.  So a brain nodule would be a small collection of cells that form a roughly circular shape located in the brain.  These could be benign or represent cancer, especially cancer that has spread from another part of the body.
