As the most common malignant tumor of the breast, there is no clinical basis to believe that physical exercise or physical rubbing will lead to the occurrence of breast cancer. According to current clinical epidemiological statistics, the risk factors for breast cancer are mainly related to obesity, high-fat diet, early menarche and late menopause, and also have a certain family genetic susceptibility, which is not correlated with external forces, so frequent breast rubbing will not lead to breast cancer. For breast cancer, the current clinical treatment strategy is early detection, early diagnosis and early treatment, with radical resection and modified radical treatment, combined with axillary lymph node dissection, and postoperative chemotherapy, radiotherapy and even molecular targeted drugs.
