The positive relationship between physical exercise and cancer is widely justified in the literature, but an emerging research line warns of its capacity to improve the effectiveness and reduce the toxicity of cancer treatment (responsible for the appearance of side effects and comorbidities), that overload the health care system. To date, there is a lack of knowledge in different subjects: the possibility of implementing individualized exercise programs in clinical environment to mitigate the side effects of cancer treatment; the best moment in natural history of the disease to perform therapeutic exercise; and a tailored dose of exercise that maximizes its benefits.
In this context, the present study will evaluate the effects of a therapeutic exercise program conducted previously at the beginning of the cancer treatment, in the treatments' toxicity against the same program conducted during cancer treatments in women with breast cancer, and its positive effects on both clinical and biological variables and their possible impact on disease-free survival.
This study will be conducted in 3 phases with 110 participants in total: phase 1: a pilot study be carried out to check the feasibility of the proposed physical exercise program; phase 2: to test the effectiveness of the program ATOPE performed prior to surgical medical treatment against the same made during treatment, with a randomized controlled clinical trial; and phase 3: in which it will be integrated into the health service and a larger project will be requested at the international level.
