Oncology/Surgical

Okay so after doing some soul searching and some research I believe that i have finally found what I want to do with my life. Which is nursing. I know that I have posted a thread not to long ago but sense then I have been thinking. Can anyone please give me some advice on what I should do? I want to either be in oncology or surgery. If anyone are in these fields please give me some heads up. Like pros, cons, salary, where you work (hospitals clinics office?) So if anyone could help me it would be greatly appreciated.
