Physical activity does not protect against in situ breast cancer, epidemiological study finds

Non-invasive or in situ breast cancer is characterized by the fact that it does not invade or does not multiply in other cells and unlike invasive breast cancer, it is not benefited by physical exercise. The experts suggest that exercise would only have protective effects once the tumour starts to invade the breast tissue. A European study has analyzed the association between physical activities and in situ or non-invasive breast cancer, or, in other words, cancer that has not yet invaded cells within or outside of the breast.
