How does it work?
The basis of radiotherapy is to damage the genetic material (DNA) of cancer cells or tumor samplers to override their ability to reproduce. The body eliminates the dead cells naturally.
The drawback is that sometimes normal cells are also affected by the radiation, but they have the ability to repair in cancer cells there.
The oncologist, by analyzing prepared an action plan whereby protecting the surrounding normal tissue as possible.
