Hi, Welcome to Health care magic forum.
As you describe,there were fibroid
in the uterus
, and the doctor ordered for further examination, the reason may be that the cervix
is not allowing the IUD, to pass. the reason may be fibroid.
Don't worry there will be a long way before carcinoma to appear.
Confidently attend the doctor, in your appointment.
wishing for a quick and complete recovery. Thank you.
