LDR prostate brachytherapy (seed or polymer source implantation) is a very effective treatment for low to high risk localized cancer, with patients rapidly returning to normal activities.[15] Although patients may experience problems (urinary incontinence or difficulty with urination) for the first 6 months or so after their implant, these usually settle down and lasting problems are rare, only occurring in about 1–2% of patients.[16] Some patients (less than 10%) report an increase in bowel problems (diarrhea or urgency of the bowels), but again this usually settles down without further treatment.[17]
