After prostate cancer radiation treatment

Tiredness, urinary irritation and bowel changes can take time to settle. Keep appointments for symptom review and PSA blood testing, and report new problems rather than assuming every change is an expected effect of radiotherapy.

Radiation can irritate the bladder, urethra and rectum near the prostate. This may cause a stronger urge to urinate, a weaker stream, burning, looser stools, rectal discomfort or small amounts of rectal bleeding. Erectile changes can emerge more gradually because treatment can affect blood vessels and nerves.

PSA does not always fall immediately after radiation because prostate tissue remains in the body. Your clinician interprets the pattern across several results rather than relying on one value. Hormone treatment given alongside radiation can also affect energy, mood, temperature regulation, bones and sexual function.

Pace activity around fatigue, but keep gently active if your team has not restricted exercise. Drink enough to avoid dehydration while following any advice for bladder, heart or kidney conditions. Note which foods or drinks worsen urinary or bowel irritation and discuss changes before cutting out major food groups.

Tell the team about leakage, urgency, pain, bowel symptoms or erection difficulties; medicines, pelvic-floor support and specialist sexual-health care may help. Continue prescribed hormone therapy and other cancer medicines exactly as directed. Record symptoms and PSA appointment dates so trends are easier to discuss.

Get urgent medical help if you cannot pass urine, pass large blood clots, have heavy rectal bleeding, develop severe lower abdominal pain, or feel faint or acutely unwell. Fever with painful or difficult urination can point to infection and needs prompt assessment.

Contact your oncology team for worsening urinary flow, persistent blood in urine or stool, ongoing diarrhoea, new swelling in a leg, new bone pain, or symptoms that disrupt sleep and daily activity. Late effects can arise after treatment has finished and can still be assessed and treated.

Clarify the expected PSA pattern, the schedule for testing, and which change would prompt imaging or another treatment discussion. Ask which urinary or bowel effects should be referred to a specialist, how hormone therapy affects the recovery plan, and what options are available for sexual rehabilitation.
