If the size, shape and nature of a solid breast nodule are different, different treatment methods can be adopted: 1. If the volume of a solid breast nodule is small, and benign lesions such as breast fibroids are considered through ultrasound examination, and there is no obvious pain or discomfort, you can take the method of regular review of ultrasound to closely observe the changes in the breast nodule, and if the volume of a solid breast nodule increases during the review process, surgery can be considered. If a solid breast nodule is large in size, even if the nodule is a benign lesion, it is possible that the larger nodule may compress the normal breast gland and milk ducts and affect future breastfeeding, so it is recommended that the patient undergoes surgery to remove it as soon as possible. 3. If a solid breast nodule is considered to be a malignant tumor, it is recommended that the patient undergoes tumor removal as soon as possible and at the same time performs peripheral lymph node dissection, which can be combined with chemotherapy after surgery to achieve better treatment results.
