Answer:
<h2>Laser Surgery.</h2>
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:
- Teletherapy.
- Brachytherapy.
- Systemic radioisotope.
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.
However, one common technique used is laser surgery to treat cancer, because through this way a laser beam can be aimed precisely to destroy specific tumors.
Therefore, the best answer here is laser surgery.
