brain tumour

[lara]

why do tumours in brain not metastasize???

[neslihan]

cause nerven cells can not reproduce. but there is another question. if they can not reproduce, how can lung canser spread to brain? there are other small cells in brain, which can reproduce.

Quite true. Brain tumors are not caused by the haotic division of brain cells(neurons). they are caused by the division of glial cells, helper cells of the neuron, who are even in healthy state 10 times more numerous than them. Glial cells divide into: astrocites, schwamm cells, oligodentrocytes and glioblasts

That's not right. Brain tumors DO metastasize. But the fact is that the person usually dies before metastasis. Plus, some benign tumors in brain, such as meningioma (hope I remember its english name right), can metastasize too. This is what a neurosurgery professor said.

Brought to you live by Poison, our cancer specialist.

[Poison]

I'm trying to be a cancer specialist, Andrew. Thanks.

[Dr.Stein]

I will not add any comments. This section belongs to Poison, she does it very good Good luck with your plan, and yes that's a good choice, don't take Immunobiology, Endocrinology, and/or Reproductive Biology as your subject, they are mine!!! Ahahahahahahaa

Fuhh....lucky me ecause I take Virology und iochemistry....
just imagine if I tke immunebio....I'll get a snake bite around my body...

[Poison]

yes, cancer can be studied in many fields, molecular bio, biochemistry, genetics and so on. But I prefer molecular bio and biochemistry.

Well, OK Dr. Stein, I won't get Immunobiology.

If anyone touches cell bio and/or photosynthesis you're dead!!

[Poison]

oh, some cell bio wouldn't hurt, Andrew. ( I will need it for cancer ) But photosynthesis is yours. Take it and have fun.

[MrMistery]

Which reminds me, i need to brush up on my photosynthesis, i haven't revised the biochemical pathways for several months now...
