Practicing Sport in the Age Group 21-34 and the Risk of Breast Cancer - Analysis of the Results of a Retrospective Study

Breast cancer is the most common malignant tumor in women, so it is important to study the factors that can protect against it. One of them is physical activity, which has become the area of our interest, especially the practice of sports by women aged between 21 and 34. The aim of this retrospective study was to check how practice of sport in the age group of 21-34 in women from the research group diagnosed with breast cancer and in the control group (healthy women from families burdened with this cancer) influences the risk of developing breast cancer. The study showed that healthy women from families with a burden of breast cancer practiced sports in the age range 21-34 more frequently and intensively than women who had a history of breast cancer. (Sport 1-highest intensity P = 0.002 Sport 2-medium intensity P < 0.001 Sport 3-the lowest intensity P < 0.001.) It can be concluded that practicing sport in the age group of 21-34 is an important factor in the prevention of breast cancer, although the influence of other protective factors in women from the control group cannot be ruled out.
