Radiotherapy meaning

Radiotherapy, also known as radiation therapy, is a medical treatment that uses high-energy radiation to kill cancer cells and shrink tumors. It works by damaging the DNA of cancer cells, which inhibits their ability to grow and divide. Radiotherapy can be used as a primary treatment for cancer, as well as in combination with surgery, chemotherapy, or immunotherapy. There are different types of radiotherapy, including external beam radiation therapy, which directs radiation from outside the body, and internal radiation therapy (brachytherapy), which involves placing radioactive material inside the body near the tumor. Radiotherapy is carefully planned and administered to maximize its effectiveness while minimizing damage to surrounding healthy tissues.
