Radiotherapy is a medical treatment that uses ionizing radiation to kill or control the growth of cancer cells. It targets specific areas of the body to minimize damage to healthy tissues.

Radiotherapy works by damaging the DNA of cancer cells, which prevents them from replicating and leads to cell death.
Common types of radiotherapy include external beam radiation therapy (EBRT) and brachytherapy.
Ionizing radiation used in radiotherapy can be delivered using X-rays, gamma rays, or charged particles like protons.
The dosimetric planning process is critical for determining the optimal dose distribution to maximize tumor control while minimizing exposure to surrounding healthy tissues.
Side effects of radiotherapy can include fatigue, skin irritation, and long-term risks such as secondary cancers due to radiation exposure.
