Brachytherapy

Brachytherapy is a form of radiation treatment that places a radiation source close to or inside a tumor to target cancer while limiting exposure to nearby tissue.

  • Brain & Spine Tumors

    We have decades of experience caring for patients with brain & spine tumors, pioneering minimally invasive treatments and leading research for new treatments to improve patient outcomes.

What Is Brachytherapy?

Brachytherapy is a treatment that delivers radiation from inside the body or very close to the area being treated. Unlike external radiation, which comes from a machine outside the body, brachytherapy uses a small radioactive source placed in or near a tumor for a planned period of time.

This approach may be used in carefully selected cases when a physician wants to concentrate radiation in a specific area while helping reduce exposure to surrounding tissue. The right approach depends on the tumor type, its location, prior treatment and the patient's overall health.

Why Choose Baptist Health?

At Baptist Health Brain & Spine Care, patients receive evaluation and treatment planning from physicians who focus on complex neurologic conditions and tumors. Care is coordinated across specialties so each treatment plan reflects the tumor location, symptoms, imaging findings and other therapies.

Because brachytherapy is highly specialized, treatment planning is important. Our experts work to guide patients through each step, explain options in plain language and support informed decisions about care. When appropriate, patients may also need imaging, surgery or other radiation-based treatments such as Radiosurgery as part of a broader plan.

Why Choose Baptist Health?

How It Works

Brachytherapy works by placing a radiation source directly into or near the treatment area. This allows a high dose of radiation to be focused where it is needed most. The source may stay in place temporarily or in some cases permanently depending on the treatment plan.

The exact technique varies. Physicians use imaging, treatment planning and careful placement to target the tumor as precisely as possible. For some patients, brachytherapy may be used after surgery or along with other cancer treatments.

Who May Benefit

Brachytherapy may be considered for some patients with tumors in the brain or spine, or for tumors near these structures, when focused radiation is appropriate. It may also be discussed when a tumor has returned after prior treatment or when limiting radiation exposure to nearby tissue is especially important.

A full evaluation is needed to decide whether this treatment is suitable. Your physician will review the tumor type, size, location, previous treatments, symptoms and overall health before recommending a plan.

Benefits and Risks

A possible benefit of brachytherapy is that it can deliver radiation very close to the tumor with limited exposure to nearby healthy tissue. Depending on the situation, it may also shorten the treatment course compared with some other radiation approaches.

Risks depend on the tumor location, how the radiation source is placed and whether surgery or anesthesia is part of treatment. Possible concerns may include:

  • Swelling
  • Irritation of nearby tissue
  • Infection
  • Bleeding
  • Side effects related to radiation

Your care team will explain the expected benefits and risks for your situation.

What to Expect

  • Before brachytherapy, you may have imaging studies, lab work and visits with your treatment team. Your physician will explain why brachytherapy is being considered, how the radiation source will be placed and whether anesthesia or a procedure is needed.

  • During treatment, the radiation source is placed in or near the target area using the method chosen for your care plan. Some treatments are completed during one procedure, while others may involve more than one step. Your team monitors the placement carefully to help protect nearby tissue.

  • After treatment, your team will review recovery instructions, follow-up visits and any symptoms that should prompt a call. Some patients go home the same day, while others may need monitoring in the hospital, depending on how the treatment was performed and their overall condition.

Recovery

Recovery varies based on the tumor being treated, the placement method and whether brachytherapy was combined with surgery or another procedure. Some people resume usual activities quickly, while others need more time for healing and follow-up care.

Your physician will tell you what activity limits, medicines, imaging and follow-up appointments are needed. Ongoing monitoring is important to assess response to treatment and watch for side effects.

Frequently Asked Questions

  • Brachytherapy places the radiation source inside the body or very near the tumor. External radiation delivers treatment from a machine outside the body.

  • Not always. Brachytherapy is a radiation treatment, but placing the radiation source may involve a procedure. Your physician will explain whether surgery, anesthesia or another technique is needed.

  • Candidacy depends on the tumor type, size, location, prior treatment, symptoms and overall health. A full evaluation is needed before a physician can recommend this treatment.

  • The treatment schedule varies. Some patients have a single treatment session or procedure, while others may need a different schedule based on the care plan.

  • Risks vary by the area being treated and how the radiation source is placed. They may include swelling, bleeding, infection, irritation of nearby tissue or other radiation-related side effects.

  • Yes. Follow-up visits are important so your care team can monitor healing, review symptoms and check how the tumor is responding to treatment.

  • Yes. Depending on your condition, options may include monitoring, surgery, systemic therapy or other radiation treatments such as Radiosurgery. Your physician will review the options that fit your diagnosis.
