Hi. A colposcopy after a diagnosis of ASCUS (atypical squamous cells of undetermined significance) is done to verify the presence of "dysplasia" or cancerous cells in the cervix. Now, you're asking if this is a routine procedure. Flynn, et al (2001) did a study on the proportion of women with a diagnosis of ASCUS who were found to have dysplasia on subsequent follow-up examinations. They found that 29.5% of women under 50 and 12.8% of women over 50 years have dysplasia on follow-up. So to answer your question: a follow-up colposcopy is probably necessary for women who are under 50 and who have been diagnosed with ASCUS, since there's a high possibility that the ASCUS indicates dysplasia. In women over 50 with ASCUS, the colposcopy is probably optional since the chance that there's no dysplasia is around 87%, but you may still want to take the option of having this done, just to make sure you are not among the 12.8% who do have dysplasia.
HPV infection is a very common infection, particularly among women who have already started being sexually active. Most HPV infection is asymptomatic and resolves spontaneously. But a small proportion can become chronic (the virus stays in the body for a long time), and cause cancer by inducing mutations on the cells lining the cervix. Cervical cancer takes years to develop (usually decades) from the initial HPV infection.
Well, my pelvic ultrasound came back and it read my uterine lining is 5mm with some pockets of fluid of undetermined significance. My ovaries are fine. I am going for an endometerial biospy and a colposcopy in two days. this all started with some spotting which has stopped. What could the fluid be? My doctor said she would be able to evaluate this when I go in? Could this be related to Ascus and does this mean cancer. I can't seem to find anything on uterine fluid unless is relates to pregnancy and I am definetly no pregnant. There is no history in my family of anything.
