Radiation treatment, employed by medical specialists called radiation oncologists, utilizes high-energy x-rays to target and eliminate cancerous cells. The process involves delivering radiation to cancer cells, damaging their genetic material (DNA), and impeding their growth or causing their death. Radiation therapy is a versatile approach suitable for treating a variety of cancers. This article presents an in-depth exploration of radiation treatment, its diverse forms, and its significance in cancer therapy. Radiation therapy's effectiveness stems from its ability to target and eradicate cancer cells with precision while preserving healthy tissues. The treatment plans are tailored to the specific needs of each cancer patient, ensuring optimal outcomes.
