Why does womb cancer cause persistent pelvic pain?

Womb cancer begins in the lining of the uterus. As abnormal tissue grows, it may trigger inflammation or stretch sensitive tissues in the uterus and pelvis. Pain can feel like an ache, pressure, cramping, or discomfort during movement or sex. Bleeding between periods, bleeding after menopause, unusual discharge, or changes in urination or bowel movements can occur alongside pelvic pain. These symptoms have many possible causes, so pain alone cannot identify the cause.

A clinician may ask when the pain began, whether it is constant, and how it affects sleep, activity, bleeding, urination, or bowel movements. Examination and targeted tests help distinguish womb cancer from other pelvic conditions.

Arrange a medical assessment for pelvic pain that persists, returns, or changes. Keep a simple record of its location, character, triggers, associated bleeding, temperature, bowel or bladder changes, and medicines used. Bring a list of relevant diagnoses and treatments. Until assessed, use only pain medicines that are suitable for you and follow the label or a clinician’s instructions; some medicines are unsuitable with kidney disease, ulcers, blood thinners, or pregnancy.

Seek urgent medical help for severe or rapidly worsening pelvic pain, heavy vaginal bleeding, fainting, marked weakness, a swollen or rigid abdomen, repeated vomiting, inability to pass urine or stool, or fever with feeling very unwell. If womb cancer is already diagnosed, contact the oncology team promptly when new pain appears or prescribed pain relief no longer controls it.

Ask what could be causing the pain, which examination or scan is appropriate, whether abnormal bleeding changes the evaluation, how to use pain relief safely, and which symptoms should prompt an urgent call. If cancer has been diagnosed, ask whether the pain suggests local pressure, treatment effects, or another condition.
