Which is the name of a doctor who cures/ helps cancer?

Lots of folks: Cancer is usually treated by medical oncologists (give chemo), surgeons (do surgery), and radiation oncologists (give radiation) but we can't forget the large supporting cast of general practitioners and many other medical specialists plus nurses, techs of all kinds, social workers, nutritionists and a ton of other folks who are part of the team (including patient and family). It's a group effort.
