Dr Kanchho, i like your optimism. Could you lend me  some?

 

With all your cancer research background you can get into a high powered clinical oncology fellowship. I think your future to me sounds like an avid basic science researcher and a master clinician.  For oncology I would suggest you to aim for the top or not worth your time spent with the MD/PhD program: Mayos, Hopkins, Mass General, Columbia, MD Anderson, Sloan K etc. I do not mean to scare you but lets count the number of boards you will be taking hereafter:

 

MCAT

USMLE Step 1

USMLE Step 2 CK

USMLE Step 2 CS

USMLE Step 3

In training examintations (ITE) during your residency period

ABIM (after your residency and this is for Internal Medicine)

Heme/Oncology subspeciality board (after your Oncology fellowship)

Recertification for ABIM and Hem/Oncology every 10 years

 

Quitters don't win and winners don't quit!!

MD/PhD rocks. You will become a different breed. So go for it man!!
