Re: how many years does it take to become a surgeon?

Depends on what type of surgeon you are trying to become.

But lets start with pre med

That is 4 years and then you have to get admission into med school.
That then takes 4 years. Then you have to find a sutable residency 
position in a surgical program.
The surgical program you join depends on what type of surgeon you would 
like to be. If you want to be a general surgeon you have between 5 to 7 
years of trainig depending on whather you like to do a year  or two in 
research.
If you would like to be a neurosurgeon that takes 6 years.
If you would like to be a heart surgeon that takes 7 to 9 years.
The salary is dpendent on what kind of practice you join. Some jobs start 
at 200,000. Some start at 125,000.
Some eventually may pay 700,000. 
All depends.
Private practitioners make more.
Some times less.
All depends on how you build your practice.
Hope this helps.
Good luck.
