What Is Brachytherapy?
Brachytherapy is a form of internal radiation therapy in which a radioactive source is placed inside the body, directly in or close to a cancerous tumor. This allows radiation to be delivered to a specific treatment area while limiting exposure to surrounding tissues.
Brachytherapy may be recommended for certain cancers, including cervical, prostate, breast, head and neck, and eye cancers, depending on the cancer type, stage, tumor location, and overall treatment plan.
How Does Brachytherapy Work?
During treatment, a radiation source is delivered using a catheter, needle, applicator, or another specialized device. Depending on the treatment plan, the radioactive source may remain in place temporarily or, in some cases, as a permanent implant. High-dose-rate (HDR) brachytherapy delivers radiation for a short period before the source is removed, while low-dose-rate treatments may involve longer exposure.
Preparation, Side Effects and Recovery
Before treatment, your radiation oncology team may review your medical history, perform an examination, and use imaging to plan accurate placement of the radiation source. Possible side effects depend on the treated area and may include temporary discomfort, fatigue, irritation, or other site-specific effects. Your doctor will explain precautions, recovery, and follow-up care based on your treatment plan.
