What this Trial Is About

Breast cancer remains the most common cancer among women and a major cause of death despite advances in screening and treatment. Current screening programs are not personalized and are experiencing declining participation. A promising strategy for breast cancer control would be to implement risk-based prevention and early screening, targeting individuals at high risk of developing breast cancer, in order to improve chances of cure and reduce the need for more intensive treatments. The MyPeBS study was designed to assess whether personalized breast cancer screening (based on an individual's risk of developing breast cancer) is as effective as, or more effective than, current standard screening. Lifestyle interventions involving changes in diet or physical activity, for example, have been shown to be effective in reducing the risk of developing breast cancer, whether low or high. The MyPeBS study evaluates personalized screening but offers limited information on breast cancer prevention. MyPREV is a project that aims to assess the feasibility and impact of a personalized online program on breast cancer risk reduction measures. This program is offered to women at high risk of developing breast cancer as part of the European MyPeBS screening study. The main objective is to evaluate adherence to a personalized, online breast cancer prevention program focused on lifestyle and its acceptance among women at high or very high risk of developing cancer who participated in the MyPeBS study.
