Therapeutic X-ray is designed to do which of the following?

• A. Only Used Diagnostically
• B. Not Used Clinically
• C. Weaker Than Diagnostic X-Rays
• D. Used to Treat Diseases and Kill Certain Cells

Answer: (D)

Therapeutic X-ray is about using radiation with the goal of treating disease, especially cancer, by delivering controlled, higher doses to destroy cancer cells. The radiation damages the DNA of those cells, which prevents them from dividing and leads to cell death, helping to shrink or control tumors. This treatment is planned and delivered in a way that aims to spare as much normal tissue as possible, through techniques like fractionation and precise targeting. In contrast, diagnostic X-rays are meant only to image body structures and use much lower doses, so they’re not intended to kill cells. The idea that therapeutic X-rays are simply weaker isn’t accurate—the purpose, dose, and technique are different because therapy aims to treat disease, not just image it.
