There are very few jobs in expensive big coastal cities, so dont count on getting a 300k revolving private practice slot, and the 700k in the boonies is not something I have encountered. Lots of specialties have peaks and troughs, We just have a huge peak (more than doubling in 12 years residency slots) while demand in terms of the number of fractions- is going down. 10 years ago, palliative xrt used to be 250 x 15, prostate 180 x44, breast- 33 treatments etc. Palliative care is 50% of most practices, so that alone is a big hit. Yes, we are treating a bit more oligo mets, but oligo fractionation for a few extra oligomets will in no way offset the decline in total number of fractions. Our professional society leadership,ASTRO, actually receive short term benefits from this situation. I just dont know of an analagous situtation in another specialty.
Anthony Zeitman, program director at MGH, invoked syphilology - the specialty treating syphilis- when discussing our future, and then falsely claimed that the "free market" would solve the problem, despite the fact that once a residency slot is opened up, a horrible job market will not close it down, but just lead to it being filled by a desperate FMG.
At the end of the day, it is about your expectations. When I entered the field, I expected (basically felt entitled) to a good job in the city of my choosing, and that is what I got and the field has been very good to me, but I would not go into it today.. As has been said before, medicine has a lot of interesting specialties....
