Describe how high-energy X-rays can treat tumours.
Model answer
What a good answer should say
- High-energy X-rays treat tumours by delivering targeted radiation that damages the DNA of cancer cells, inhibiting their ability to grow and divide.
- This method can shrink tumours or eliminate them entirely, depending on the dosage and precision of the treatment.
Explanation
