Nowadays, the pace of life is getting faster and faster, and the status of women has been largely enhanced. However, the unique physiological structure and physical differences make many women take on too much mental and physical work, and under the heavy pressure, women in the workplace have a high chance of developing breast cancer. Breast lumps are arguably the most common female breast disease, and if not prevented and detected early, they may turn into breast cancer. Breast lumps are the most common symptom of breast cancer, and about 90% of patients come to the clinic with this symptom. With the popularization of cancer knowledge and cancer screening, this percentage may increase. If a lump appears in the breast, the following aspects should be understood. The location of the lump should be noted. The location of lumps in general breast disease is different from that of breast cancer. The breast gland is centered on the nipple and makes a cross, which can divide the breast into internal upper, external upper, internal lower, and external lower Nowadays, the pace of life is getting faster and faster, and the status of women has been largely enhanced. There are more and more women among the top managers of many companies and enterprises. However, the unique physiological structure and physical differences make many women take up too much mental and physical work, and under the heavy pressure, women in the workplace have a high chance of suffering from breast cancer. The number of breast lumps varies greatly, and the most common type of breast cancer is a single lump on one side of the breast. The most common type of breast cancer is a single lump on one side of the breast. Multiple lumps on one side and primary bilateral breast cancer are not common in clinical practice. However, with the improvement of tumor prevention and treatment, patients’ survival period is increasing, and the chance of having a second primary cancer in the opposite breast will increase after surgery for one side of breast cancer. Among the symptomatic manifestations of early breast cancer, the size of the lump is also an important aspect, and the difference in size can be easily confused with other diseases. Early breast cancer lumps are usually small and sometimes not easily distinguished from lobular growths or some benign lesions. However, even a small lump can sometimes involve the suspensory ligament of the breast and cause symptoms such as local skin indentation or nipple retraction, which are easier to detect at an early stage. In the past, due to poor health care, lumps were often larger when they came to the clinic. Nowadays, with the popularization of breast self-examination and screening, the number of early stage breast cancer has increased clinically. Through the above examination tools, we found that breast lumps are one of the more obvious features of early breast cancer. However, it is only through careful examination and analysis that we can accurately determine whether it belongs to the category of breast cancer or just a common breast enlargement or other diseases. Women in the workplace should take care of their breast health to protect their work, family and life.
