neuroscience - Are there any types of cancer that cause neurons to divide?

I think that most mature cells do not divide in all tissues. If organism need to repair tissues, it uses tissue cell precursors -- stem cells.



In case of neurons, these are neuroblasts. Neuroblasts can divide and can repair brains under some circumstances (I don't know under which).



There is a cancer grown from neuroblasts, called neuroblastoma.



I think it is very unprobable to have tumor from neurons, because division gens are turned of in mature cells. Can't state it is not occurring in practice.
