The document discusses guidelines for cervical cancer screening, including incorporating HPV testing. It finds that HPV testing for women over 30 with ASCUS can reduce unnecessary colposcopies by identifying HPV-negative patients with very low risk. However, HPV testing also poses problems like increased anxiety and many HPV-positive women referred for colposcopy having normal results. Overall, HPV testing may help triage some abnormal pap results but also adds new issues to consider.

17. A province wide cervical screening program with an adequate recall mechanism is recommended.

25. These recommendations do not apply to those women who have had previous abnormal Pap tests. Screening at a 3 year interval is recommended, supported by an adequate recall mechanism. Screening interval · Screening should be done annually until there are 3 consecutive negative Pap tests. · Screening should continue every 2 to 3 years after three annual negative Pap tests.
26. Women who have sex with women should follow the same screening recommendations as women who have sex with men. Pregnant women should be screened the same as women who are not pregnant . Discontinue cervical screening in women who have undergone total hysterectomy for benign causes. Immunocompromised or HIV positive women should receive annual screening.
75. Women with AGC should also receive endocervical and endometrial sampling, where appropriate. High grade SIL, ASC-H, Atypical Glandular cells Colposcopy
