OK, I finally had to jump in here. My wife completed her Hem/Onc fellowship a year ago, is just wrapping up a 12-month BMT fellowship and will be starting as an asst. prof in BMT (or HSCT as they prefer to refer to it) next month. I read her some of the posts, and she especially enjoyed John's list of all the "cool procedures."
Hem/Onc in general (and BMT/HSCT in particular) are in no way procedurally related. With the exception of the biopsy, now done by techs, NPs, fellows, the occasional resident, sometimes housekeeping, and even the random brave/delusional patient him/herself, there are no procedures. Hell, most of these docs (my wife included) would take over an hour to get a simple IV started. Don't even get me started on central lines (that's mostly IR now, at least for tunneled caths).
Sure, from time to time they'll go look at a smear (well, at least they'll send a fellow to go do it), but the MD never does their own smear. That's hematopath's job: to set it up, put it under the scope and focus it for the doc.
Apheresis is "done" by Hem/Onc'ers the way that an O&P is "done" by the ID team. They order it to be done. Again, this is hooking up lots of very technical tubes to lines, not a busy MD's strong suit. We have techs for this just like we do for dialysis.
Blood banking is done by -- wait for it -- techs. The Division of Hem/Onc may very well run the blood bank at your hospital, but they're simply management.
I couldn't think of any procedures Hem/Onc and/or BMT/HSCT docs do on anything other than an annual basis, so I asked my wife. She just laughed and said, "Look, if I wanted something procedural, I'd have gone into surgery, right?" Or at least Rad Onc....
