Screening for cancer beyond recommended upper age limits: views and experiences of older people

BACKGROUND: Internationally, screening programmes and clinical practice guidelines recommend when older adults should stop cancer screening using upper age limits, but it is unknown how older adults view these recommendations. OBJECTIVE: To examine older adults' views and experiences about continuing or stopping cancer screening beyond the recommended upper age limit for breast, cervical, prostate and bowel cancer. DESIGN: Qualitative, semi-structured interviews. SETTING: Australia, telephone. SUBJECTS: A total of 29 community-dwelling older adults (=70-years); recruited from organisation newsletters, mailing lists and Facebook advertisements. METHODS: Interviews were audio-recorded, transcribed and analysed thematically using Framework Analysis. RESULTS: Firstly, older adults were on a spectrum between trusting recommendations and actively deciding about cancer screening, with some who were uncertain. Secondly, participants reported limited in-depth discussions with health professionals about cancer screening. In primary care, discussions were focused on checking they were up to date with screening or going over results. Discussions mostly only occurred if older adults initiated themselves. Finally, participants had a socially- and self-constructed understanding of screening recommendations and potential outcomes. Perceived reasons for upper age limits were cost, reduced cancer risk or ageism. Risks of screening were understood in relation to their own social experiences (e.g. shared stories about friends with adverse outcomes of cancer treatment or conversations with friends/family about controversy around prostate screening). CONCLUSIONS: Direct-to-patient information and clinician support may help improve communication about the changing benefit to harm ratio of cancer screening with increasing age and increase understanding about the rationale for an upper age limit for cancer screening programmes.
