Nodules on the breast should be examined and treated in a regular hospital because they can be benign or malignant. If the patient does not go to the hospital for examination in time, if the nodule is malignant, the lump will increase in size over time and may lead to local skin depression or color change, or even breakage and bleeding to form ulcers. There is also a possibility that the tumor may lead to lymph node metastasis or distant metastasis, which may endanger the patient’s life. If benign nodules are not treated in time, the nodules may continue to grow and cause breast pain and make surgery more difficult. Generally, breast ultrasound, mammography and other examinations are needed to determine the benignity or malignancy of the nodule, and if necessary, puncture or complete removal of the nodule can be done and sent for pathological examination.
