A woman in Minnesota named Jen Pratt was diagnosed with cancer over 20 years ago when she was 11.
She needed surgery and about a year of chemo.
After, she decided to pursue a career in medicine, and went to medical school.
She is now Dr. Pratt and working in the SAME hospital that treated her when she was a kid.
Some of her nurses are still there; she gets to work with them every day.
