I have been attending tumor boards on a weekly basis in some capacity or another for over 20 years, since starting my pathology residency. Prior to then, I observed as a medical student on a regular basis. Even if I was on a rotation, like family practice or pediatrics or OB/Gyn, if I had the time, I would try to attend one of the many tumor boards on the hospital campus. I kept the schedule in my PalmPilot Personal Digital Assistant at that time.
