Does womb cancer cause bleeding between periods?

Womb cancer starts in the lining of the uterus. Bleeding between periods can happen when this lining changes or becomes fragile. Most bleeding between periods is not caused by cancer; hormonal contraception, fibroids, polyps, infections, pregnancy-related problems, and changes around menopause can also contribute. The pattern matters, including when it happens, how long it lasts, and whether it follows sex.

Book an appointment with a doctor or gynaecologist if bleeding between periods is new, recurring, or unexplained. They may ask about contraception, pregnancy possibility, medicines, and menstrual history, then examine you or arrange tests. Keep a note of dates, flow, clots, pain, and related symptoms. Do not stop prescribed contraception without advice.

Seek urgent care if bleeding is heavy enough to cause weakness, faintness, or shortness of breath, or if it occurs with severe pelvic pain, fever, or a possible pregnancy. Prompt review is also appropriate for bleeding after sex or bleeding that continues despite a normal cycle pattern.

Ask what causes are most relevant to your age and history, whether a pregnancy test or examination is needed, and which tests would assess the womb lining. Ask when to return if the bleeding continues or changes.
