3. Specialty Choice :

   • Radiation Oncology : You can enter Radiation Oncology directly after completing your MBBS, without needing to complete Internal Medicine or Pediatrics first. This is because Radiation Oncology is typically a distinct specialty in itself.
   • Pediatric Oncology : For Pediatric Oncology, you need to complete a residency in Pediatrics first. Once you complete your Pediatric residency, you can then pursue a super-specialty in Pediatric Oncology.

In summary, if you're interested in Pediatric Oncology, you'll need to first complete a residency in Pediatrics. For Radiation Oncology, you can directly enter the specialty after your MBBS, but a high NEET PG rank will improve your chances of getting into a good program.
