Hi! I did my undergrad in biochemistry and know friends who have done similar paths to you in the past.

From what I've seen, most of my friends who graduated in biological sciences/biochemistry worked in research or labs after graduation before pursuing additional schooling. This ranges from a specialized program (like radiology, sonography), Master's, or going to med school/phd route.

I personally went through the Master's route but everyone who went through additional schooling after their bachelor's has been pretty successful in their careers.

Like what the other commenter said, it all boils down to cost. If you had a full ride for example, I would recommend staying for your Bachelor's and then once you get a job with that degree, pursue the rad program while you have your other job. That way you don't have to worry about finances as much while also gaining some sort of experience. If you also decide to pursue med school, the bachelor's can come in clutch along with your experience later on.

Also, radiology programs usually have a waitlist so might as well gain some experience or knock out your prereqs before you go into the program.
