Swissfag here, I'll start studying medicine this September. It will be 6 years until I'll have to decide in what direction but I'm really considering going into nuclear (aka nucular) medicine. Any thoughts about it?
Do it.
Radiation oncology is pretty cool.
I'm a physicist at a medical device manufacturer that makes brachytherapy sources. I'll probably be going back to school in the near future for medical physics, though I don't have any plans to practice clinically.
Also make sure to ignore all the "CT causes cancer" threads.
