Radiation therapy uses high-energy beams (like X-rays) to destroy the DNA of cancer cells so they can’t grow or multiply.
In Plain English: Think of this as a “targeted strike.” While chemo works on the whole body, radiation is aimed exactly at the site of the tumor.
When it’s Used: For Osteosarcoma, radiation is less common because these cells are often “radioresistant.” However, for Ewing Sarcoma, radiation is a vital tool, especially if the tumor is in a place where surgery is difficult, like the pelvis or spine.
The Experience: The treatment itself is painless and usually only takes a few minutes, but it is often given daily over several weeks.
