The Study is Observational and Retrospective: Lifestyle, BMI and Activity Physical.

The goal of this observational-retrospective study is to learn about the long-term effects of a lifestyle intervention inclusive of dietary counselling and physical activity advice, on body weight in female breast cancer survivors who took the intervention in previous years compared to those who did not take it. The main question it aims to answer is: Does a long-term lifestyle intervention help to control body weight 5 years after breast cancer diagnosis? Participants are asked to answer online survey questions about their anthropomethry, clinical conditions, socio-economical status, dietary habits, physical activity levels, quality of life, sleep quality and pshycological distress.
