What is Brachytherapy?
Brachytherapy is a targeted radiation therapy for various cancers like prostate, breast, neck, and head. It involves placing radioactive pellets near the tumor to destroy cancer cells. These implants emit radiation for a short period, shrinking or eliminating tumors. Brachytherapy can be temporary or permanent, administered alone or in combination with other treatments.
When compared to other radiation therapies, the advantages of brachytherapy include accuracy, targeted therapy, quick recovery, preserving the nearby organs, shorter hospitalizations, and quick recovery.
Types of brachytherapy Treatment
Brachytherapy is mainly classified based on the location of the implant and the dose-delivery (source loading).
Based on the location of the implant:
Based on the location of the implant, brachytherapy is categorized into interstitial brachytherapy (placed inside the tumors or within the tissues), intracavitary brachytherapy (placed inside the cavity), intraluminal brachytherapy (placed within the organ or passage), and surface brachytherapy, also called mold brachytherapy (placed on the surface of the body).
Based on the dose-delivery (source loading):
Based on the dose delivery, the brachytherapy is categorized into HDR brachytherapy (high-dose rate brachytherapy), LDR brachytherapy (low-dose rate brachytherapy), and PDR brachytherapy (pulsed-dose rate brachytherapy).

Brachytherapy: Pre-Op & Post-Op Care
Preparation for brachytherapy
The doctor conducts assessment and imaging tests, evaluates medical history, recommends the required dose, and initiates therapy with standard instructions for the procedure and diet before starting the therapy.
What happens during the brachytherapy?
Followed by the anesthesia administration, the surgeon inserts a catheter or applicator device to send radioactive implants to the tumor, using imaging to ensure correct placement. The implant stays in place for specific durations, depending on the type of brachytherapy. HDR involves implant removal after treatment sessions, while LDR allows for re-insertion or placement throughout treatment.
After the procedure
Post-treatment, pain relief medications are given, and activity is restricted with ample rest. Patients are closely monitored and provided instructions for resuming their routine. Doctor’s guidance is vital, especially regarding safe interactions with others, particularly during permanent brachytherapy, to prevent radiation exposure.
Recovery from brachytherapy
Brachytherapy recovery varies based on the patient’s condition, type of brachytherapy, radiation location, and overall health. However, most of the patients can recover within a few days to a few weeks and engage in their regular activities.
Post-procedure care
Post-procedure care involves-
- Doctor’s medication for pain management.
- Rest and avoid strenuous activity until cleared by the doctor.
- Maintain a healthy diet and fluid intake.
- Possible constipation or diarrhea, managed with stool softener or medication.
- Regular follow-up appointments to monitor side-effects.
- Potential need for additional imaging tests like CT scans or MRIs.
