Explanation:

Radiation therapy is one of the most used treatments of cancer. It uses ionizing radiation that is focused on a specific zone.

There are three divisions of radiation therapy:

These three divisions are used to specific positions. For example, radioisotopes are given by infusion or oral ingestions, which are targered later by a beam radiation.
