Breast cancer incidence increases with advancing age and continues to increase after the age of 65, as does mortality. Yet in most countries, no screening provision is made for this population at high risk of the disease as current evidence suggests that their low compliance wouldn't justify their inclusion in a screening program. It is important to examine what factors influence an older woman to accept an invitation for breast cancer screening or not. Thus a two-part trial to assess the acceptability of breast cancer screening to women aged 65-74 in central London was conducted. in the first part of the study, all eligible women (from 500) aged 65-74 in a central London district were invited to come for single view (medio-lateral oblique) mammographic screening, following the same procedures as those in the National Health Service National Breast Screening Program. Part two of the study is a survey of attenders and non- attenders of the invitation, including those aged 60-64 as a comparison group. outcome measures for part one of the study include: attendance rates, % abnormal mammograms, recall rates, biopsy rates, cancer detection rates, and stage of tumour. Outcome measures for part two include: acceptability, reasons for non-attendance, health status measurement, effects of disability on attendance, and mammography usage.
