you zoom in, spray vinegar on it, and look for acetowhite changes (thicker abnormal skin will pick up the vinegar)
then biopsy
What’s between CIS and invasive cancer?
microinvasion - when you get a few cells under the GBM - measured in milimeters of depth (it’s a minute change)
How is cervical cancer staged beyond microinvasion?
clinically - no matter what they find on biopsy or surgery, the staging stays the same.
True or false: invasive cancer can be missed by a pap
true - but the clinical should see it
