<b>Brachytherapy</b> is implant radiation therapy.  For most types of implants, you will need to be in the hospital.

<b>Interstitial Radiation</b> --implants are put directly into the tumor.

<b>Intracavitary Radiation</b>  --implants are placed in special applicators inside a body cavity.

<b>Intraluminal Radiation</b> -implants are placed in special applicators inside a body passage.
 
<b>Remote brachytherapy</b> --a computer sends the radioactive source through a tube to a catheter that has been placed near the tumor. The radioactivity remains at the tumor for only a few minutes. In some cases, several remote treatments may be required and the catheter may stay in place between treatments. High dose-rate (HDR) remote brachytherapy allows a person to have internal radiation therapy in an outpatient setting. High dose-rate treatments take only a few minutes. Because no radioactive material is left in the body, the patient can return home after the treatment. 

<b>Unsealed internal radiation</b> --given by injecting a solution of radioisotope into the blood, or into a body cavity, or giving an oral dose of a target-seeking radioisotope.  

<b>Intraoperative Radiation</b> combines surgery and radiation therapy. The surgeon first removes as much of the tumor as possible. Before the surgery is completed, a large dose of radiation is given directly to the tumor bed (the area from which the tumor has been removed) and nearby areas where cancer cells might have spread. This can be done by external beam or by exposure to other radiation source. Sometimes intraoperative radiation is used in addition to external radiation therapy. This gives the cancer cells a larger amount of radiation than would be possible using external radiation alone.
