What Is Brachytherapy (Internal Radiation Therapy)?

Brachytherapy is a type of radiation therapy where radioactive material is placed directly inside or near a tumor. It delivers a high dose of radiation to cancer cells while minimizing exposure to surrounding healthy tissue. It is commonly used for prostate, cervical, uterine, breast, and skin cancers.

Preparation Guidelines of Brachytherapy (Internal Radiation Therapy)

  • Pre-treatment imaging and planning scans (CT, MRI, or ultrasound) are performed.
  • Discuss current medications and medical history with your oncology team.
  • Fasting or other preparation may be required depending on the procedure site.

What to Expect

Small radioactive sources are placed inside the body, either temporarily (removed after a few minutes to days) or permanently (tiny seeds left in place). The procedure may require anesthesia or sedation, depending on the cancer location. Treatment length varies from a single session to several days.

Risks and Complications of Brachytherapy (Internal Radiation Therapy)

  • Temporary pain, swelling, or irritation near the treatment site.
  • Urinary, bowel, or sexual side effects depending on the treated organ.
  • Rare long-term complications such as scarring or tissue damage.

Results and Follow-Up of Brachytherapy (Internal Radiation Therapy)

Your oncology team monitors tumor response through imaging and exams. Brachytherapy is often combined with surgery, external radiation, or chemotherapy. Follow-up continues for months to years to track treatment effectiveness and side effects.
