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.
The lymphatic system helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream. It also helps defend the body against infection by supplying disease-fighting cells called lymphocytes.
