What is a DSC file? Files with the .dsc file extension store information about photographs that have been taken with a Nikon Coolpix digital camera. These files are saved on the camera's memory card along with the corresponding image files. DSC files do not contain any actual image data.
A colposcopy is a procedure that uses a colposcope (a lighted magnifying instrument) to examine the vulva, the vagina and cervix. A colposcopy is done after an abnormal Pap test or a positive HPV test suggests a precancerous condition of the cervix or cervical cancer.
Alternatively, the woman may have another HPV test that looks specifically for HPV-16 and HPV-18, the two HPV types that cause most cervical cancers. If either of these two HPV types is present, a woman will usually have follow-up testing with colposcopy.
