brachytherapy
Pronunciation: BRAK-ee-ther-ah-pee
Radiation therapy delivered by placing radioactive sources directly into or near tumor tissue, commonly used for cervical and endometrial cancers.
Full Definition
Brachytherapy is a form of internal radiation therapy where radioactive sources are placed directly into or adjacent to the tumor site. In gynecologic oncology, it is frequently used as part of definitive treatment for cervical cancer and as adjuvant therapy for endometrial cancer. The technique allows for high-dose radiation delivery to the target area while minimizing exposure to surrounding normal tissues. Common applications include intracavitary brachytherapy for cervical cancer and vaginal cuff brachytherapy following hysterectomy for endometrial cancer.
Usage
Usage note: Always lowercase unless beginning a sentence. Distinguish from external beam radiation therapy in treatment descriptions.
