The material describes radiotherapy as a treatment using what?

Explanation:
Radiotherapy works by using high-energy radiation to damage the DNA of cancer cells, making it hard for them to repair themselves and to divide. This can shrink tumors or stop their growth. The radiation can come from outside the body or be placed inside the body near the cancer. Cancer cells are often more vulnerable to this damage because they’re dividing rapidly and have less robust repair mechanisms, while most normal cells can recover better. Vaccines stimulate the immune system, antibiotics treat bacterial infections, and surgical removal is a physical way to take out a tumor—so those methods aren’t radiotherapy. The description focusing on high-energy radiation to kill cancer cells is the correct understanding.
