Breast nodules appear lobulated, which can indicate an irregular pattern. In this case, the breast nodule may be a benign lesion or a malignant tumor, which needs to be highly valued, and you may consider going to the hospital for examination to determine the disease. Breast nodules are lobulated and structurally disorganized, regular review of breast color Doppler ultrasound is recommended. If the location of the lesion appears very close to the chest wall, a puncture biopsy may be an option. Puncture biopsy can also directly detect malignancy or benignity. To avoid delays, it is best to have a targeted pathologic biopsy. If it is a benign breast fibroid, local excision can be enough, but for lobulated malignant tumors, it is best to do radical mastectomy. After surgery, further treatment will be based on the pathologic results.
