Brachytherapy
What Is Brachytherapy?
Brachytherapy is a highly effective, minimally invasive form of internal radiation therapy used to treat certain types of cancer, including non-melanoma skin cancers such as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). It delivers a targeted dose of radiation directly to cancerous tissue while minimizing exposure to surrounding healthy skin.
How Does Brachytherapy Work?
Unlike traditional radiation therapy—which uses external beams to target tumors—brachytherapy involves placing a small radioactive source either on the surface of the skin or just below it, right at the site of the tumor. This allows for a precise, localized treatment that delivers high doses of radiation exactly where it’s needed.
There are two main types of brachytherapy relevant to dermatology:
- Surface (or contact) brachytherapy: The radiation source is placed directly on the skin over the lesion.
- Interstitial brachytherapy: For deeper or more invasive skin cancers, the radioactive material may be placed just beneath the skin surface.
Benefits of Brachytherapy in Dermatology
- Precision targeting: Protects surrounding healthy skin and underlying tissues.
- Minimal scarring: A great option for cosmetically sensitive areas like the face, nose, ears, and scalp.
- Outpatient procedure: Often completed in just a few short sessions without the need for surgery.
- High success rates: Proven effective for early-stage, localized skin cancers.
Who Is It For?
Brachytherapy may be a suitable treatment option for:
- Patients with non-melanoma skin cancers located in areas where surgery might be difficult or disfiguring.
- Elderly patients or those who are not good candidates for surgical procedures.
- Individuals seeking non-surgical alternatives for skin cancer treatment.
What to Expect
The treatment process typically involves:
- Assessment and planning: Imaging and skin mapping help define the treatment area.
- Application of the radioactive source: A custom applicator may be used to deliver the therapy directly over the lesion.
- Short treatment sessions: Usually completed over several days (e.g., 1–2 weeks).
- Post-treatment care: Most patients experience only mild skin irritation or redness, which resolves over time.
Is It Safe?
Yes. Brachytherapy is a well-established, FDA-approved cancer treatment. The radiation is confined to the treatment area, with minimal risk to other parts of the body. The procedure is carried out by a team of trained specialists, including radiation oncologists and dermatologists.
