Attitudes towards risk-stratified breast cancer screening in Denmark - a qualitative study

Today the prerequisites exist to initiate risk-stratified screening according to a woman's individual risk of breast cancer as opposed to existing one-size-fits-all age-based programmes. This presupposes that the women accept having their personal risk score estimated and their screening intervals changed accordingly. Risk-stratified screening has not yet been implemented in any country, but in the future many European countries will very likely move towards more personalized screening. This qualitative study among 46 women aged 50-69 years used an anthropological approach and interpretive description. Data was collected using semi-structured focus group interviews and telephone interviews. The interviews were analysed using systematic text condensation. The aim of this study was to explore Danish women's understanding of breast cancer risk and their attitudes towards the concept of risk-stratified breast cancer screening. The women highly valued the current screening program, seeing regular mammograms as crucial for early detection. The women had good knowledge of the causes of breast cancer, but they had not given much thought to their own risk. They found a personalized screening approach more reliable than age-based screening, understanding that low risk is not the same as no risk just as high risk is not equal to ever developing breast cancer. Despite concerns about increased anxiety arising from knowing one's risk, they appreciated the possibility of more frequent screenings for high-risk individuals. In general, the women showed acceptance of a new breast cancer screening concept estimating their personal risk score. Due to concerns about interval cancers and the prolonged screening intervals for women at low risk, offering more intensified screening for high-risk women may be less challenging than deescalating screening for low-risk women. Whether the expressed positive attitude and curious interest will translate into actual participation if implemented, remains to be investigated further in an ongoing Danish trial.
