question: Hi.  I am a 51 year old woman who had a cervical polyp removed approximately 3 months ago.  I am still having bleeding after sex so my doctor had a sonogram done and it showed that I still have thickening of the lining.  She thinks that the polyp may have grown back, even though it is rare, or it may be something else.  What else could it be and if it is the regrowth of the polyp what does that mean?  My doctor said that I have precancerous cells, what are the chances that if it is a polyp that it will be cancerous?
