  1. Why is it that pathology has a difficult time attracting competent, high quality medical students to the field whereas radiology, a similar field, is exceptionally competitive? All of the top quality medical students that I tutor who would be great pathologists are using it as a backup, instead ranking radiology higher. This is simply disappointing.

    I think that to advance our field beyond being considered a commodity, we need to attract top talent. We are thus far failing in this regard. It’s probably a multifaceted issue involving lab avoidance, autopsy avoidance, future disruptive technologies, low prestige, and relatively low income to other similar alternatives.

    We also need to get ourselves into the boardrooms of medical school admissions committees and to the reimbursement negotiating tables if we want the field to provide the best possible diagnostic quality to patients. As it stands, I fear we are working at less than optimal capacity.

    1. I don’t know if I agree with Mr. Cobb. I know some very bright people who have chosen to go into pathology.

      And the Ontario Sunshine list would suggest Pathologists do very well, thank you… certainly better than my specialty.
