Estimated volumes of a high grade cytology results; b colposcopies; c precancer treatments; and d precancer treatments in women aged less than 45 years by year with and without the impact of HPV vaccination: comparison of current program with proposed pathway. High grade cytology results: those with a result of HSIL or ASC-H (Atypical squamous cells, possible high grade lesion) in The Bethesda System 2001; ASC-H is equivalent to possible HSIL in the Australian Modified Bethesda System 2004. High grade cytology results do not include those performed as a reflex test for women testing positive for HPV 16/18 at the primary test, nor those resulting from samples collected at colposcopy
