$70k at year one but rapidly rising through to 2 or 300k within a decade.
That may of been the case 20 years ago, but these days, to become a specialist in a particular area or a GP, you can't really start training in any of these areas unless you have at least 10 years experience of working in hospitals. So to see these sort of high incomes, you probably will be in your early 40's at the absolute earliest (assuming you complete a 3 year science degree and swap over into a 5-6 year medicine degree).
