Pap Smear Abnormalities
Precancerous changes of the outer (squamous) cells of the cervix have the potential to turn into cancer if left untreated. In the cervix these precancerous changes are called ‘Cervical Intraepithelial Neoplasia’ or CIN for short.
There are different grades of CIN according to how severe the changes are, from CIN1 minor change referred to as Low Grade Squamous Intraepithelial Lesions (LSIL) to CIN 2 and CIN 3 referred to as High Grade Squamous Intraepithelial Lesions (HSIL).
The risk of CIN1 developing into cancer is very small, however we know that CIN2 and CIN3 may develop into cancer in some cases, if left untreated.
