Exam-style question
Try this first
When considering patient safety, what is a key difference between implants and external radiotherapy?.
- A.Implants expose surrounding tissues to less radiation than external radiotherapy.
- B.External radiotherapy is safer because it uses lower doses of radiation.
- C.Implants can be removed if side effects occur, while external therapy cannot.
- D.External radiotherapy requires longer treatment sessions than implants.
Model answer
What a good answer should say
- Implants expose surrounding tissues to less radiation than external radiotherapy.
Explanation
Why this works
Radioactive implants deliver targeted radiation directly to the tumor, resulting in less exposure to surrounding healthy tissues compared to external radiotherapy, which can affect a larger area. This makes implants a safer option for minimizing collateral damage.
