What is Radiation Therapy?
Radiation is a form of energy and is everywhere in the atmosphere. Microwaves zap your food with radiation. The sun heats the earth through radiation. And radiation makes it possible to see broken bones through x-rays. Radiation is also used to kill cancer cells and to shrink tumors. In a nutshell, radiation destroys the genetic material that cancer cells use to reproduce. Without the code needed to multiply, cancer cells eventually shrink and die off. The machines used to target cancer cells must be extremely precise to prevent damage to surrounding healthy cells. Radiation can also be applied inside the body using seeds and pellets about the size of a grain of rice and made out of radioactive material which are placed on or near the cancer site. Moshura's radiation is a targeted external radiation therapy using high energy rays to shrink any cancer cells surrounding the area where the tumor was removed from his leg. I imagine the machine used for his radiation is similar to the one in the video above. They can tell you more about it. I think the video provides a good visual of what it may be like. Above is one man's experience during radiation treatment of his brain tumor.
