How are radioactive seeds used to treat prostate cancer?
A doctor or clinician implants radioactive (iodine-125 or palladium-103) seeds into the prostate gland using an ultrasound for guidance. The number of seeds and where they are placed is determined by a computer-generated treatment plan tailored for each patient.
How is radiation used to treat cancer?
Credit: National Cancer Institute. Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. At low doses, radiation is used in x-rays to see inside your body, as with x-rays of your teeth or broken bones.
How are the radioactive seeds loaded into the needle?
The radioactive seeds are loaded into the designated number of needles. In a specific order, each needle is inserted through the skin in the perineum (the area between the base of the scrotum and the anus) and into the prostate using continuous ultrasound guidance. Once accurate needle placement is confirmed, the seeds in that needle are released.
What are radioactive seed implants?
Radioactive seed implants are a form of radiation therapy for prostate cancer. Brachytherapy, or internal radiation therapy, are also terms used to describe this procedure.
How long are you radioactive after brachytherapy?
No radiation remains in your body after temporary brachytherapy, so there is no risk to others. Some LDR, PDR and HDR treatments require one or more days in the hospital and may cause discomfort. This may be due to the catheters or applicators and having to stay relatively still for a prolonged period.
What is seed treatment for cancer?
Permanent seed brachytherapy (pronounced brack-ee-therapy) is when your doctor puts very small radioactive metal seeds into your prostate gland. The seeds slowly release a low level of radiation into the area of the prostate over a few months. It is a type of internal radiotherapy.
Is brachytherapy a surgery?
Brachytherapy is a form of radiation therapy used to treat various cancers. Treatment involves surgically placing radioactive seeds, capsules or other implants directly in or near the cancerous tumor. The implants give off radiation for a short time.

What is the success rate of brachytherapy?
Brachytherapy increases the 9-year success rate from 62 percent to 83 percent for those with intermediate to high-risk cancer. The overall outlook for people with prostate cancer, regardless of treatment plan, is excellent.
What cancers are treated with brachytherapy?
Brachytherapy is a type of internal radiation therapy that is often used to treat cancers of the head and neck, breast, cervix, prostate, and eye. Brachytherapy is a type of internal radiation therapy in which seeds, ribbons, or capsules that contain a radiation source are placed in your body, in or near the tumor.
Who is a candidate for brachytherapy?
The best candidates for LDR brachytherapy are low-risk prostate cancer patients. The criteria for low-risk groups are a PSA level<10 ng/ml and Gleason scores≤6. The next ideal candidates for LDR brachytherapy are intermediate-risk prostate cancer patients with organ-confined disease.
How many sessions of brachytherapy are there?
You may undergo one or two sessions a day over a number of days or weeks. You'll lie in a comfortable position during high-dose-rate brachytherapy. Your radiation therapy team will position the radiation device. This may be a simple tube or tubes placed inside a body cavity or small needles inserted into the tumor.
Do you lose your hair with brachytherapy?
