Great question! You are right that cancer is due
to rapid division of cells, that neurons don't
usually divide after the brain forms, and that the
brain has more cell types than just neurons.
That's pretty impressive for someone your age.
Brain cancer can come from cells other than
neurons. For example, glial cells support neurons
and help them work. They can become cancer cells.
Cells that form linings, coverings, or glands in
the brain can all form tumors, which can be
Some cancers in the brain come from cells in
other places in the body that travel to the brain.
Replacing lost or damaged neurons would seem
like a good thing. Why do you think they don't
You seem to have a promising future in a field
like cell biology.
Thanks for asking,
