Radiation beads for prostate cancer: what to know

This approach is a form of brachytherapy. A specialist uses imaging and treatment planning to position the sources in the prostate. Some sources remain in place and release radiation gradually; the exact approach depends on the treatment plan and the cancer’s features.

The procedure may involve anaesthesia and temporary urinary symptoms afterwards. Burning, urgency, a weaker stream, bowel irritation or blood in the urine can occur. Sexual changes are also possible. Your team will explain restrictions, medicines and follow-up before you leave.

Tell the team about blood thinners, urinary difficulty, previous prostate procedures, allergies and other medicines. Follow instructions about fluids, prescribed medicines and activity. Keep follow-up appointments so the team can assess urinary function and review the response to treatment.

Be precise about the name of the treatment: implanted sources are different from external radiotherapy and from targeted radioisotope therapy, which uses a medicine that travels in the body. Your specialist can explain which option matches your scans and goals.

Contact your treatment team if urinary burning, bleeding, pain or urgency is worsening rather than settling, or if you develop fever or chills. Seek urgent care if you cannot pass urine, have heavy bleeding, severe pain, or develop sudden weakness or loss of bladder or bowel control.

Are implanted sources suitable for my prostate cancer and urinary function? Will the sources stay in place? What precautions apply around other people? Which medicines should I stop or continue? Who should I call if passing urine becomes difficult?
