Radiation Therapy

Radiation therapy damages cancer cells' DNA, which either kills them or limits their growth at high dosages. Cancer cells that have DNA damage that cannot be repaired either cease proliferating or die. When the injured cells expire, the body degrades and eliminates them. Radiation therapy does not instantly eradicate cancer cells. Before cancer cells experience enough DNA damage to cause them to die, days or weeks of treatment are required. After radiation therapy is finished, cancer cells continue to perish for a few weeks or months. It is frequently employed to treat cancer. Radiotherapy is a component of the treatment plans for around half of all cancer patients. In addition to cancer, radiotherapy is sometimes used to treat thyroid illness, various blood problems, and benign (non-cancerous) tumours.
