Despite the fact that 90% of cervical cancers can be prevented by regular Pap screening, many women are not screened regularly, particularly older women. To understand better the barriers to screening, the authors held five focus groups during April 2000 in Prince Edward Island (PEI), Canada. Of the 32% of women aged 45 to 70 who had not been screened over a 5-year period (1995-2000), 60 randomly selected women participated in this research. The authors analyzed discussions for themes using an inductive approach, with interpretation guided by the population health model. Women who have avoided a Pap test are falling between the cracks created by a complex interaction between personal experiences and the health system's approach to Pap screening.
