It will be hard to get a loan if you have no job and little income. Especially now that the financial institutions are cracking down on that. Giving mortgage loans to people who couldn't afford them was part of the problem of the housing market and financial collapse.
Talk to some surgeons and see what they say. They might have some advise on these things. As for if they'll give you loans for top surgery just tell them it's for surgery (if they even ask). You probably won't have to go into detail with them.
