The other day I when I was with a cardiologist, he mentioned that he only "deals" with cardio stuff and considers himself fairly inept when handling anything that ventures outside of the CV system. I mean obviously he trained in IM and this isn't completely true, but he has been out for awhile, so it's not too surprising. Is this sort of attitude common in Oncology as well? I would think Oncologists would have to be very competent internists in order to be good at their job, perhaps more than a cardiologist or gastroenterologist would, for example. The reason I'm asking is while I am really interested in oncology, I also really don't want to lose out on a lot of my IM knowledge. I would consider that a huge turn off for entering any field. What do you guys think?
