Prostate Seed Brachytherapy

Who can have seed brachytherapy?

Seed brachytherapy is commonly used to treat early stage prostate cancer confined within the prostate. The PSA should be under 10 and the Gleason Score 6 or less. If these parameters are not met, brachytherapy alone may not be the best option. In addition, there should be no evidence of urine blockage, and the prostate gland should not be too big.

There are three steps in having a prostate implant:

  1. A planning trans-rectal ultrasound called a TRUS)
  2. Implanting the radioactive seeds
  3. A CT scan one month later to check the implant
