New growth. Does it sound like a band? Or a groupie thing like new age something?
The medical term for new growth is neoplasm, meaning the growth of new tissue which shouldn't have been there in the first place. A euphemism for tumor.
How long does it take to remove a new growth the size of an egg?
The answer is Location Location Location.
If it's on an extremity, maybe thirty minutes to a couple of hours. Longer if it is inside the body cavity and attached to some other organs.
But if it is inside the brain, then twelve hours is about it.
Having said that, I will go to sleep now.
