Brachytherapy for Prostate Cancer

Brachytherapy, also known as internal radiation therapy, is a form of radiation treatment effectively used for various cancers, including prostate cancer. This technique involves placing a sealed radiation source inside or next to the area requiring treatment. Unlike traditional external beam radiation therapy, which delivers radiation from outside the body, brachytherapy works internally, allowing for higher doses of radiation to be directed at more specific areas.

For prostate cancer, radioactive seeds are typically implanted directly into the prostate gland. There are two main methods of brachytherapy used in treating prostate cancer: low-dose rate (LDR) brachytherapy and high-dose rate (HDR) brachytherapy.

LDR brachytherapy, the more common method for prostate cancer, involves inserting tiny radioactive seeds, about the size of a grain of rice, into the prostate gland using needles. These seeds are left in place permanently, emitting low-level radiation over weeks or months. Their radioactivity diminishes over time until they become inactive. Conversely, HDR brachytherapy involves temporarily placing radioactive sources into the prostate gland through catheters for a few minutes at a time. The treatment may include several sessions over one or two days, after which the radioactive material and catheters are removed.

Brachytherapy for prostate cancer offers targeted radiation, minimizing the impact on surrounding healthy tissues and organs. LDR brachytherapy is typically an outpatient procedure, allowing patients to return home the same day. This treatment has proven effective for localized prostate cancer, which is confined to the prostate gland.

Despite its benefits, brachytherapy can have potential side effects and risks, including urinary problems like frequency, urgency, and discomfort during urination. Some men may experience erectile dysfunction or bowel issues. Most of these side effects are temporary and manageable with medication or lifestyle adjustments.

In summary, brachytherapy represents a potent tool in the fight against prostate cancer. It provides a less invasive, more precise approach to radiation therapy, particularly beneficial for localized prostate cancer cases.
