Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop:
Any vaginal bleeding after menopause
Bleeding between periods or a persistent change in your periods
Ongoing pelvic pain, pressure, or abdominal swelling
A pelvic lump or symptoms that are getting worse
If you have already been treated for uterine sarcoma, contact your cancer team about new or persistent symptoms rather than waiting for the next routine visit.
Every sign above is quoted from the sofidex article on Uterine sarcoma. If you are not sure, err upward — it is always reasonable to be checked.
