Lobular hyperplasia is the most common type of non-neoplastic, non-inflammatory proliferative lesion among breast hyperplastic diseases, accounting for about 70% of breast diseases, and can occur in women of any age after puberty.

The palm of the hand should be flat when touching the four fingers together, using the most sensitive index finger, middle finger, ring finger end fingers in order to gently search the outer upper and outer lower, inner lower, inner upper area of the breast, and finally the nipple and areola area in the middle of the breast. Do not use your fingers to grasp and pinch the breast tissue during the examination, otherwise the grasped breast tissue will be mistaken for a lump. 2.From sitting position any nipple inversion skin depression structure shape abnormality is a clue of deep breast cancer. If the patient claps her hands on her head to contract the pectoral muscles, the above signs will appear, and when the woman is in sitting position, it is easy to check the lymph nodes above and below the clavicle and in the axilla. Finally, palpation should be performed in a sitting position by touching the area under the nipple with joined fingers. 3. In the supine position, a more extensive palpation of the area is performed. A pillow is placed under the ipsilateral breast and the ipsilateral hand is raised above the head so that the breast is evenly spread on the chest wall, making it easy for the fingers to reach the deeper part. The palm surface of the middle finger of the index finger, not the fingertip, should be used for palpation, and palpation should be performed by turning the nipple outward in a circle, and it is especially important to examine the breast that extends to the axilla. 4, breast examination should first observe the development of the breast.
