how many years does it take to become an oncologist
Kudos to those who can do it. Mike. It takes 4 years of college, 4 years of medical school, 3 years of residency, and 3 years of fellowship to become an oncologist. Essentially, you don't starting getting paid till you're at least 32 years old with about $200,000 dollars in debt.udos to those who can do it. Mike.
