It's so insane to read so much on this stuff, and everyone has a slightly different "story"/"opinion" on it. I kept freaking out thinking I had warts on my cervix, because some places insisted if I had CIN 1, aka mild dysplasia, that it was automatically low risk hpv. Which is what I personally don't want. It took breaking down in my dr's office, and a few posts on hpv boards, to realize that's not necessarily true. Dysplasia doesn't automatically mean warts
Rogue....can you explain more about this stuff to me? What is CIN 1?
The terminology used with HPV and Pap smear interpretation can be confusing, even more so due to differences in systems used by labs to classify Pap results. This brief glossary defines common terms.
CIN: Cervical Intraepithelial Neoplasia. Another system for classifying the tissue changes indicated by abnormal Pap test results, CIN refers to abnormal cervical cell changes that are usually indicative of HPV, especially in younger women. CIN is classified as 1, 2, or 3 depending on the size and severity of lesions. CIN 1 is a viral infection. CIN 2 and CIN 3 are considered cancer precursors in the US. CIN 2 is considered an extension of CIN 1 in many European systems.
Squamous Epithelium: comprised of a layer (or layers) of tough, flat cells, squamous epithelium is a type of tissue that protects organs by covering and lining them. The vagina, for example, is lined with squamous epithelial cells. The area of the cervix where these cells overlap with the more delicate, mucous-producing glandular cells of the uterus is known as the transformation zone, an area of great cell turnover making it susceptible to abnormal cell growth. Carcinomas are cancers that occur in many types of cells including epithelial cells.
ASC-US: Atypical Squamous Cells of Undetermined Significance. This means atypical cells are present, but it isnÃ¢â‚¬â„¢t clear what may be the cause. ASC-US has been defined to be based on how the cells appear; and not confused with other vaginal infections or cellular repair from tampon use or intercourse. To help sort through possibilities a Pap test may be repeated in a few months, HPV DNA testing may be done or, a colposcopy performed.
SIL: Squamous Intraepithelial Lesion. A classification system for Pap test results that refers to abnormal cell growth of the cervix. SIL is further classified as Ã¢â‚¬Å“low-gradeÃ¢â‚¬Â (LSIL, can equate to CIN 1) or Ã¢â‚¬Å“high-gradeÃ¢â‚¬Â (HSIL, can equate to CIN 2 or 3).
Let me know if this is Too Much Information, or just confuses the matter more!
