First, I would strongly suggest you read the FAQ as most of your questions are answered there.
do you think Rad Onc could someday go the way of CT surg now? by that i mean the treatment modality is no longer in as much demand and there ends up being way too many people trained for it ith not enough jobs?
No. As a matter of fact I think Rad Onc will force
other specialities to go the way of CT surgery. For instance (again, as stated in the FAQ), stereotactic body radiosurgery (SBRT) has been shown to be equivalent to surgery in terms of local control for early stage lung cancer and (probably) superior in terms of side effects. There are numerous other examples of this in our field.
As to the second part of your question, the # of radiation oncologists in our field is conservatively and aggressively regulated by the powers that be. A few years ago, there was a predicted excess of practicing radiation oncologist so residency slots were cut significantly. This prediction turned out to be false so they beefed up slots subsequently.
or could it go the way of nuclear medicine, similar in that it is not really popular now and there aren't many jobs in it?
One of the main problems with nuclear medicine is that much of their training is included in the course of a diagnostic radiology residency. Thus, it makes more sense to hire a radiologist as they can do a lot more than a nuc med physician.
You cannot draw a similar analogy to our field as no other speciality subsumes the training that we receive.
i never get a serious answer about what people really think the future of xrt is?
That's because nobody can seriously predict the future. Especially when there are so many variables involved.
people in other specialties think radiation will be looked at like blood-letting some day in that its brutal and a primitive treatment for how cancer will some day (maybe in the next 20 yrs) be treated. blood letting is obv an extreme example but you get the picture. its discouraging because I really like the idea of a career taking care of cancer patients with radiation technology but i can't help but wonder about the future
Some "people" also beleive that the Holocaust never happened, that the Earth is flat, and the the government is hiding alien corpses in Roswell. So what?
Again read the FAQ.
Let me say NO OTHER SPECIALITY has any idea what the hell we do. Maybe it's easier to think that we just "push the button." Our field is incredibly complex and sophisticated. Surgeons may think they can do SBRT and it's all fun and games until a patient winds up with a spinal cord transection or goes blind.
Perhaps I can explain things this way. The unit of radiation is the Gray (Gy). If people get a whole body exposure of ~ 4 Gy, 50% of them will die within several weeks. We routinely adminsiter more than TWENTY TIMES this dose to various parts of the body including the head and neck and prostate to treat cancer. There is a reason our residency is four years.
