What should you know about groin pain and prostate cancer?

Muscle strain, hip or pelvic joint problems, urinary symptoms, nerve irritation and treatment effects can all cause discomfort near the groin. Prostate cancer may also cause pain in the pelvis or nearby bones, particularly when disease has spread, but groin pain alone cannot establish that explanation. Tell your team where the pain begins, whether it travels, what worsens it, and whether you have difficulty passing urine, blood in urine, leg weakness or new back pain.

Arrange a clinical review if the pain persists, limits walking or sleep, or changes over time. Bring a list of medicines and note urinary, bowel, sexual, and movement-related changes. Your clinician may examine the abdomen, groin, hips and back and decide whether urine tests, blood tests or imaging are appropriate. Treatment choices for prostate cancer can include surgery, radiotherapy, brachytherapy, medicines or bone-strengthening treatment, depending on the findings.

Seek urgent help if you cannot pass urine, develop sudden leg weakness or numbness, lose bowel or bladder control, or have severe rapidly worsening back or pelvic pain. Contact your oncology team promptly for fever, unexplained swelling, blood in urine, or pain that is new and persistent.

Ask what causes are being considered, whether your prostate cancer treatment could contribute, which symptoms require urgent action, and whether evaluation of the hips, pelvis, spine or urinary system is needed.
