Understanding Radiotherapy: A Lifeline in Cancer Treatment
Radiotherapy, often called radiation therapy, is a cornerstone in modern cancer treatment. It uses high-energy radiation to destroy cancer cells by damaging their DNA, preventing them from multiplying. Unlike surgery, which physically removes tumors, radiotherapy works at a microscopic level, targeting cancer cells while striving to preserve healthy tissue around them.
The development of radiotherapy has been one of the most significant medical advancements in the last century. Early radiation treatments were quite basic, but today, technological innovations have made radiotherapy more precise and safer than ever. Techniques like Intensity-Modulated Radiation Therapy (IMRT) and Stereotactic Radiosurgery (SRS) allow doctors to focus radiation beams exactly where they are needed, minimizing side effects and improving outcomes.
Radiotherapy can be used alone or alongside other treatments such as chemotherapy and surgery. In some cases, it’s the primary treatment to shrink tumors that cannot be operated on.…
