Effects of a Physical Exercise Program in Quality of Life of Breast Cancer Survivors

A 16 weeks 3-weekly supervised and adapted physical exercise program will be applied to breast cancer survivors in surveillance and, in estrogen receptor positive cases, under hormonotherapy. The program will be applied in group classes of 20 participants, in the facilities of one local gymnasium, by fitness instructors included in the investigation team. Investigators will evaluate the Health-Related Quality of Life (HRQoL), physical activity, cardiopulmonary fitness, upper limb strength and lower limb functionality. The investigators also aim to evaluate the safety of the program and oncological outcomes such as symptoms related to disease and its treatment and, also, overall survival and disease free survival.
