i took a year off to pursue basic science bioinformatic and genomic research. at the time i didn't know that i would be going into rad onc. i was involved in multiple projects, mostly involving cancer, and had multiple 2nd and middle author publications in mid-tier journals. none of the publications were specifically in rad onc, but i was asked about my research interests and the reason why i took time off in literally every interview. i loved my experience and still love it, so i didn't mind talking about it at all! i know it helped me. my research mentor also wrote me a kick a$$ letter, which was also mentioned in most of my interviews.
my numbers--3.5gpa, honors in surgery, psych, neurology, medicine, rad onc (1 at home and 1 away), boards in the 211 step 1, not aoa.
i matched at my #5 choice out of 14 ranked, not at either of the places i rotated through (which i ranked higher). Very happy with the end result and CANT WAIT UNTIL internship is over!!! i'm writing this at 2am, with 1 admission left to see!!! radonc is totally worth it...
i didn't have the numbers...just the love....and it paid off....
go for it if it's what you want to do.
