Radiation therapy stands as a cornerstone in the arsenal against cancer, offering a potent tool in the fight for healing. Its ability to target and
eradicate cancerous cells while sparing healthy tissue has revolutionized oncology treatment. This article delves into the profound impact of
radiation therapy, exploring its mechanisms, advancements, and transformative role in unlocking healing for patients worldwide. Radiation therapy,
also known as radiotherapy, utilizes high-energy rays or particles to damage cancer cells' DNA, impeding their ability to multiply and survive. Unlike
chemotherapy, which circulates throughout the body, radiation therapy precisely targets tumors, minimizing collateral damage to surrounding
healthy tissue. This precision is crucial in mitigating side effects and enhancing treatment efficacy. One of radiation therapy's defining features
is its precision. Advanced imaging technologies such as MRI, CT scans, and PET scans enable oncologists to precisely locate tumors and tailor
treatment plans accordingly. Techniques like intensity-modulated radiation therapy stereotactic radiosurgery and proton therapy further enhance
precision, allowing for highly localized delivery of radiation while sparing nearby organs and tissues.
