Normal cells can receive a certain amount of radiation safely. Which means a certain part of your body can only receive a certain amount of radiation safely for your entire life.
What is Radiotherapy?
It is the use of high-energy radiation waves targeted at the cancer area, to shrink or kill the tumour cells. It may be used in combination with surgery or chemotherapy.
It is intended to damage the DNA of the cancer cells, so these cells cannot reproduce. They then shrink, die and are eliminated by our body.
Unfortunately, radiation also destroys the normal tissue areas around the cancer cells. Our ovaries and testicles are the most easily damaged by radiation.
