New radiation treatment for prostate cancer

Modern radiotherapy uses imaging and computer planning to shape radiation toward the prostate while limiting exposure to nearby bladder and rectal tissue. External treatment delivers radiation from outside the body. Brachytherapy places radioactive sources in or near the prostate for a planned period. Targeted radioisotope therapy may be considered when cancer cells have a suitable marker and disease has spread in a way that fits this approach.

The choice depends on stage, previous treatment, prostate size, urinary symptoms, general health, and goals. Radiation may be used as a main treatment, after surgery, or to ease symptoms from cancer in another area. Side effects can include urinary frequency, bowel changes, tiredness, and sexual difficulties; timing and intensity vary.

Bring a list of medicines, prior scans, previous cancer treatments, and urinary or bowel symptoms to the consultation. Ask how the target will be mapped, how many visits are expected, and whether a treatment spacer or other planning aid is appropriate. Discuss fertility, erections, bladder control, and bowel health before deciding.

A radiation oncologist can compare radiotherapy with brachytherapy, surgery, hormone treatment, or observation when those choices fit the diagnosis. Read about [Radiotherapy](/treatments/radiation-oncology/radiotherapy/) and [Brachytherapy](/treatments/radiation-oncology/brachytherapy/) to prepare.

Contact the cancer team promptly for inability to pass urine, worsening blood in the urine, fever, severe pelvic pain, heavy rectal bleeding, or new weakness or numbness. Difficulty passing urine needs urgent assessment when the bladder feels full but urine will not come out.

Which radiation method matches my cancer findings? How will the prostate and nearby organs be protected? What symptoms should I report during treatment? How might this affect urination, bowel function, and sexual health? What alternatives should I compare?
