What causes brain cancers?
« on: 23/06/2008 13:46:04 »
Stephanie asked the Naked Scientists:

I love your show and I download the podcast every week.

The other day I was listening to an older show, you had someone ask a question about cancer and it made me wonder how brain cancer works.

I was under the impression that cancer was a cell deformity, but the brain does not produce new cells, at least thats whats I have been told, so how do brain cells mutate if they are not growing?

What do you think?

Glial cells in the brain do divide and can form cancer: Glioma

Quote
Glia retain the ability to undergo cell division in adulthood, while most neurons cannot.

Cancer in the brain can be metastatic: seeded from cancer cells from elsewhere, e.g. breast, bowel.
