eli5: How do surgeons remove a brain tumor without damaging the brain?

747 views

I’ve been watching Grey’s Anatomy (I know) and I’m curious- I know that you have to move around the ‘important parts’ to access a tumor if you’re able to even operate at all. But, how is any part of the brain ‘not important’? Meaning, how are surgeons able to touch and manipulate parts of the brain without it 1) turning into mush 2) being damaged and affected permanently ? Thank you and sorry if this is a dumb question, Grey’s has me real into this.

Not a surgeon. But my husband had brain surgery 3 weeks ago. Brain Surgeons have had enough experience and research over the years to know what they can remove and how best to remove it. The lump my husband had was right smack bang in the middle of his brain. (behind his eyes, under the cortex and in front of the cerebelllum) Surgeon went in from the back and slightly to the left. Surgery is also robot assisted. Brain surgery means all the liquid your brain floats in has to be drained away and it has the regenerate after the operation. This give you a headache. Your brain doesn’t like being dry. Going in from the back of the brain makes you very nauseated.

Going in from the front has risks of seizures and epilepsy.

Brain surgery isn’t without risks. Hubby has had a few complications, but he couldn’t keep the lump either.
