Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian cancer during their lifetime. There is evidence from the literature that for sporadic breast cancer disease risk and the course of disease can be significantly influenced by physical activity, nutrition and weight. The hypothesis of this 3 year, prospective randomized multicenter feasibility trial is that a structured life-style intervention program with exercise training and mediterranean diet is feasible and improves the nutritional and fitness status as well as the weight, the quality of life and stress reacting capacity.
