I have one, found during a hysteroscopy when I had been bleeding pretty heavily for 3 weeks (I'm 64 long since post menopausal - definitely shouldn't be happening).
Consultant said it was bleeding, & also blocking his view of my fallopian tubes. Biopsies take.
Took over 8 weeks to get result which were benign & I was given a routine appointment to have it removed. That was for last Thursday, & the thing has given me no problems whatsoever & bleeding had stopped day or two after the hysteroscopy anyway.
No surprise to have the removal procedure cancelled by the hospital 2 1/2 hours before my appointment....typical NHS.
Unfortunately, the very next day I started to have pinky reddish discharge, not on a big scale, but still ongoing, hopefully this won't continue until the new appointment, which isn't until mid July!!!
Seemed to me that was standard procedure to remove it once found, there was never any question that it would be left there.
Oddly, consultant said the ultra sounds I had beforehand shows my endometrial lining is 31mm thick, said he considered that "a bit thick", but didn't seem bothered & no mention of what to do about that.
Like you, I've had a little Google & in different circumstances I might be more concerned aboutt that than the polyp.
