What characterizes brachytherapy for prostate cancer?

Brachytherapy for prostate cancer is characterized by the implantation of radioactive seeds directly into the prostate gland. This method allows for localized treatment, delivering high doses of radiation to the tumor while minimizing exposure to surrounding healthy tissues. The seeds, which emit radiation over a period of time, can effectively target cancer cells and are often used for patients with localized prostate cancer.

This technique contrasts sharply with external beam radiation therapy, which uses outside radiation sources to irradiate the prostate. Chemotherapy, which involves the use of drugs to kill cancer cells, is a different treatment modality altogether and is not specific to brachytherapy. Additionally, surgical procedures to remove the prostate, known as prostatectomy, do not involve the use of radioactive seeds, distinguishing surgical interventions from brachytherapy. The targeted and localized nature of brachytherapy makes it a unique and effective option in the management of prostate cancer.
