The dimple sign of breast cancer refers to the invasion of tumor cells into Cooper’s ligament, which will then manifest as a significant dimpling of the breast skin. Therefore, when a significant abnormality is found in the breast, you need to go to the hospital as soon as possible to improve the relevant examination. If breast cancer is considered, modified radical mastectomy is required. Then, depending on the pathological results, chemotherapy, targeted drug therapy, endocrine therapy, radiotherapy, and Chinese medicine treatment may be required. During the treatment period, you should pay attention to your diet, for example, try not to drink alcoholic beverages, eat too greasy food and pickled food, which are harmful to your recovery. Fresh fruits and green vegetables can be consumed appropriately, and high quality protein with low fat can be consumed appropriately to improve the body’s resistance. During the treatment period, patients also need to go to the hospital for regular review, such as ultrasound, CT, laboratory tests, etc., to observe the recovery of the body.
