Brachytherapy: What You Need To Know
Brachytherapy Overview and Applications
Brachytherapy is a form of radiotherapy used to deliver radiation directly into or near cancerous tumors, aiming to target the disease while minimizing exposure to healthy tissue. This method employs tiny radioactive seeds or pellets, approximately the size of grains of rice, placed inside the body close to the cancer cells. This placement allows for high doses of radiation to be applied directly where needed.
There are different types of brachytherapy: temporary and permanent.
- Temporary brachytherapy involves the insertion of radioactive material for a specific amount of time before it is removed.
- In contrast, permanent brachytherapy involves leaving the seeds in place even after they stop emitting radiation.
Brachytherapy's applications are vast, with its use in treating prostate, breast, and cervical cancers among others. Its precision in targeting only the affected areas enables a reduction in side effects compared with whole-body treatments.
Preparing for and Understanding the Procedure of Brachytherapy
Brachytherapy is a type of radiation therapy. Radiation therapy uses high-energy particles to kill cancer cells. In brachytherapy, doctors place radioactive material inside the body.
Before the procedure, there is an appointment with the doctor to discuss the treatment plan. The doctor explains potential risks and benefits.
Understanding the procedure can reduce anxiety. The process varies depending on the location in the body where the brachytherapy will be applied:
- For prostate cancer, small radioactive seeds are placed in or near the tumor.
- For cervical or uterine cancers, a device containing radioactive material is inserted into the uterus.
The placement may cause discomfort but is generally not painful. After placing these materials, they remain in place for a duration ranging from a few minutes to several days, depending on the treatment plan.
After the procedure, patients might experience tiredness or localized pain where the material was placed, which generally subsides over time. Recovery outcomes vary.

Comparing Temporary vs Permanent Brachytherapy
Brachytherapy is a type of radiation therapy used for treating cancer by placing radioactive sources close to or inside the tumor. There are two categories: temporary and permanent.
-
In temporary brachytherapy, high-dose radiation is inserted into the body for a short duration, ranging from minutes to hours, and then completely removed. This method focuses on targeting cancer cells while minimizing damage to surrounding healthy tissue.
-
Permanent brachytherapy, on the other hand, involves the implantation of low-dose radioactive seeds in or near the tumor site on a permanent basis. These seeds emit radiation over a period of weeks to months, after which they remain in place without causing harm.
Each approach offers specific benefits depending on the characteristics of the cancer, including the location and size of the tumor. The selection of the most appropriate method is determined by evaluating these factors.
Risks, Side Effects, and Post-Care of Brachytherapy
Brachytherapy presents risks and side effects. Risks include infection, bleeding, swelling, or bruising at the treatment site, common with most medical treatments. There is also a chance of damage to nearby organs.
The side effects vary based on the treated area. In the case of prostate brachytherapy, urinary problems may occur, including:
- Frequent urination
- Discomfort while urinating
Breast brachytherapy could lead to:
- Redness
- Breast pain
- Changes in breast size
Post-care for brachytherapy patients involves regular check-ups to track recovery progress and manage any side effects that might arise over time. New symptoms should be monitored, as early detection often leads to better outcomes. Adherence to recommended diet and physical activity could support recovery, maintaining good overall health.
It is noted that the experience of treatment and recovery can differ widely among patients due to a variety of factors, including overall health condition and specifics of the procedure, emphasizing the importance of focusing on individual healing processes.
