H Doctor, I have had a lot of been in my lower groin area. I had heavy bleeding, I went to get checked and they found a polyp in my cervics, then I was sent to get an ultral sound, I had an u/s they found a 6cm x 2cm cyst on my left ovaries. my question is can that cyst that size be dangerous and does it have to be removed, im in pain and have taken pain killers with no effect thank u
