Cervical cancer is a type of gynecological cancer that begins from cells lining the cervix, the lower part of the uterus. [14] Cervical cancer begins when the cells that line the cervix become abnormal and grow in a pattern that is atypical for non-cancerous cells. [14] Cervical cancer is typically first identified with an abnormal pap smear. [14]
Endocervical curettage is a medical procedure used to extract cells of the endocervix to visualize under a microscope. Direct cervical visualization, colposcopy, and even endocervical colposcopy are not enough to fully analyze all areas of the endocervical epithelium and thus endocervical curettage is the method of choice in cases where this is necessary.
