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 that require continuity of work. Knowing the impact that short and long-term night work has on the nurses’ collective seems a priority, therefore, this study aims to analyse the relationship between night work and the development of breast cancer risk factors in nurses. For this, a cross-sectional study 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 healthy participants 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 χ2 independence test and OR calculation. The CHAID (Chi Square Automatic Interaction Detection) data mining method allowed for the creation of a segmentation tree for the main risk variables. The most significant risk variables related to working life have been the number of years worked, nights worked throughout life, and years working more than 3 nights per month. Exceeding 16 years of work has been significant for women and men. When the time worked is less than 16 years, the number of cases increases if there is a family history of cancer and if there have been more than 500 nights of work. High-intensity night work seems more harmful at an early age. The accumulation of years and nights worked increase the risk of breast cancer when factors such as sleep disturbance, physical stress, or family responsibilities come together.

La cirugía oncoplástica (COP) es un gran avance en cirugía de mama, se establece en dos niveles; el nivel 1 escisión de < del 20% de volumen mamario y el nivel 2 que abarca técnicas de mamoplastia escisión del 20-50% del volumen mamario y piel. La COP es una innovación y evolución en el tratamiento del cáncer de mama precoz, brindando un adecuado control oncológico y reflejando un grado de satisfacción alto por las pacientes. Objetivo: Conocer la viabilidad, valorar la respuesta oncológica y el producto estético de las técnicas en cirugía oncoplástica en las pacientes con cáncer de mama con un seguimiento no menor a dos años posterior a la cirugía. Material y métodos: Estudio, descriptivo, retrospectivo, la población incluye a las pacientes intervenidas por cáncer de mama con aplicación de técnicas oncoplásticas. Se utilizó para el análisis estadística descriptiva, basándonos en medidas de tendencia central. Resultados: La media del tamaño tumoral fue 25 mm, el 53.12%. La cirugía tipo 1 se realizó en 23 casos, 71.87%. Sólo se registraron dos tipos de complicaciones, hematoma en un caso 3.12% y necrosis del pezón en dos casos 6.25%. Los márgenes quirúrgicos óptimos > 2 mm se registraron en 15 casos 46.87%. En cuanto a supervivencia y vigilancia, 31 casos, 96.87% presentaron remisión completa y se mantienen libres de recurrencia locorregional en un seguimiento no menor de dos años postquirúrgicos. Conclusiones: La COP es una opción el tratamiento primario en pacientes con cáncer de mama en estadios I y II, puesto que permite un control local adecuado, preservando la estética, y no modifica la supervivencia, recurrencias locorregionales ni el índice de metástasis a distancia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
