Radiotherapy: Advancing Cancer Treatment with Precision
Radiotherapy, also known as radiation therapy, is one of the most widely used and effective treatments for cancer. It relies on high-energy radiation to destroy or damage cancer cells while minimizing harm to surrounding healthy tissue. Over the decades, radiotherapy has evolved from a basic therapeutic option into a sophisticated, highly targeted technology that plays a vital role in modern oncology.
The principle behind radiotherapy is straightforward. Cancer cells grow and divide more rapidly than normal cells, making them more vulnerable to radiation. By directing controlled doses of radiation to the affected area, radiotherapy damages the DNA of cancer cells, preventing them from multiplying. Eventually, the damaged cells die and are eliminated by the body’s natural processes. Healthy cells in the treated area can usually repair themselves more effectively, which helps reduce long-term side effects.
Radiotherapy is used in various ways depending on the…
