AB Night work has been highlighted by the International Agency for Research on Cancer(IARC) as a likely carcinogenic factor for humans, associated with breast cancer and professions thatrequire continuity of work. Knowing the impact that short and long-term night work has on thenurses’ collective seems a priority, therefore, this study aims to analyse the relationship betweennight work and the development of breast cancer risk factors in nurses. For this, a cross-sectionalstudy through an online questionnaire on breast cancer risk variables and working life was designed.The study was conducted in Spain and the sample consisted of 966 nurses, of whom 502 were healthyparticipants and 56 were breast cancer patients. These two groups were compared in the analyses.A descriptive analysis was performed, and the relationship was tested using  2 independence testand OR calculation. The CHAID (Chi Square Automatic Interaction Detection) data mining methodallowed for the creation of a segmentation tree for the main risk variables. The most significant riskvariables related to working life have been the number of years worked, nights worked throughoutlife, and years working more than 3 nights per month. Exceeding 16 years of work has been significantfor women and men. When the time worked is less than 16 years, the number of cases increases ifthere is a family history of cancer and if there have been more than 500 nights of work. High-intensitynight work seems more harmful at an early age. The accumulation of years and nights workedincrease the risk of breast cancer when factors such as sleep disturbance, physical stress, or familyresponsibilities come together.
