Low Dose Rate (LDR) brachytherapy

Low Dose Rate (LDR) brachytherapy
Treatment of prostate cancer using low-dose rate (LDR) brachytherapy was pioneered in the 1960s as an effective alternative to surgery. The word brachytherapy is derived from the Greek prefix brachy, meaning “short” or “close”, because the seeds containing radioactive material are implanted directly into the cancerous prostate gland.
Also referred to as seed implants or seeds, brachytherapy is a one-time, minimally invasive procedure usually performed in an outpatient setting under general anesthesia. The procedure itself involves the placement of tiny radioactive seeds inside the prostate using ultrasound equipment.
The seed implants immediately emit radiation and kill the malignant cells inside the prostate. The time it takes for the radiation to deliver its total dose depends on the seed (isotope) used. There are currently 3 isotopes commonly used in prostate brachytherapy: Cesium-131, Iodine-125, and Palladium-103. brachytherapy seeds themselves are compatible with human tissue.
After the procedure, patients are taken to recovery and are typically discharged a few hours later. Most patients resume normal activities within 24-48 hours. The most common side effect of LDR brachytherapy for prostate cancer is temporary urinary irritation, including frequency and urgency. These symptoms will last from a few weeks to a few months.
Understanding the LDR brachytherapy Procedure: Step-by-Step
For many patients, one of the most challenging aspects of choosing a treatment is understanding what the experience will look like. While every treatment plan is unique, understanding the general process can help reduce anxiety and provide a clearer picture of what to expect.
Before Treatment
Before recommending LDR brachytherapy for prostate cancer, physicians will conduct a thorough evaluation to determine whether the treatment is appropriate for a patient’s specific diagnosis. This evaluation may include PSA testing, imaging studies, biopsy results, prostate cancer staging information, and a review of overall health.
During this stage, patients often meet with multiple specialists, including urologists and radiation oncologists, to discuss treatment recommendations and ask questions. Many patients also seek a second opinion before making a final treatment decision.

During Treatment
LDR brachytherapy is typically performed as an outpatient procedure. During treatment, tiny radioactive seeds are placed directly into the prostate using specialized imaging and guidance equipment. These seeds gradually deliver radiation to the prostate over time while minimizing exposure to surrounding tissues.
The procedure is generally completed in a single session, and most patients return home the same day. Because the treatment is minimally invasive, many patients can resume many of their normal daily activities within a relatively short period.
After Treatment
Recovery experiences vary from person to person. Patients typically attend follow-up appointments to monitor healing, assess treatment response, and track PSA levels over time.
The weeks and months following treatment often involve adjustment and observation. While many patients return to normal routines quickly, others may experience temporary side effects that require ongoing management and communication with their healthcare team.
Understanding what to expect after treatment can help patients feel more prepared and confident throughout the recovery process.
LDR vs. HDR brachytherapy and Other Treatments
Patients considering LDR brachytherapy for prostate cancer often want to understand how it compares to other available treatment options.
Low Dose Rate (LDR) brachytherapy and High Dose Rate (HDR) brachytherapy both use radiation to treat prostate cancer, but they deliver radiation differently. LDR brachytherapy involves the permanent placement of radioactive seeds that gradually release radiation over time. HDR brachytherapy delivers a higher dose of radiation through temporary implants that are removed after treatment.
In addition to LDR brachytherapy for prostate cancer, patients may also discuss other treatment approaches with their physicians, including:
- Surgery (radical prostatectomy)
- external beam radiation therapy
- hormone therapy
- active surveillance
- Combination treatment approaches
Many families find that participating in support groups and informational meetings together helps improve communication and reduce anxiety during a stressful period. The Prostate Cancer Foundation of Chicago welcomes caregivers and family members to take advantage of available resources and educational opportunities as they help their loved ones navigate prostate cancer treatment.
Building Confidence Through Education
One of the most valuable things patients can do after diagnosis is to become informed about their condition and treatment options. While no amount of research can eliminate every uncertainty, education often helps reduce fear and improve confidence.
Patients who understand their diagnosis are often better prepared to ask questions, communicate with physicians, and participate in treatment decisions. Educational programs can also help patients develop realistic expectations about treatment, recovery, follow-up care, and quality of life.
The Prostate Cancer Foundation of Chicago is committed to helping patients access trustworthy information and educational opportunities throughout their journey. Whether through support groups, informational meetings, patient stories, or conversations with experienced professionals, the goal is to help patients feel empowered rather than overwhelmed.
Making an Informed Decision About LDR brachytherapy
LDR brachytherapy remains an important treatment option within modern prostate cancer management strategies. For many patients, it offers an effective, minimally invasive approach that can provide long-term cancer control while allowing them to return quickly to daily activities.
At the same time, treatment decisions are highly personalized. Factors such as Gleason score, grade Group, risk category, overall health, quality-of-life priorities, recovery expectations, and physician recommendations should all be considered when evaluating options.
Taking time to gather information, ask questions, seek support, and understand the full range of available treatments can help patients make informed decisions with greater confidence. If you’re among patients who are newly diagnosed, you may also benefit from learning more about how we can help after your diagnosis, including educational resources, support programs, and guidance for navigating treatment decisions.
