Patients with breast lumps or overflow, or changes in the skin of the breast, abnormal nipple areola, enlarged axillary lymph nodes, or any other signs and symptoms, should go to a regular breast specialist as soon as possible. The doctor at the breast specialist hospital will first perform a physical examination of the breast, that is, palpation, combined with mammography and ultrasound examination of the breast for diagnosis. If there are symptoms of nipple discharge, a lactoscopy should also be performed. If necessary, a preliminary diagnosis should be made in conjunction with an MRI of the breast. The final diagnosis should be based on histopathological examination, hollow-core needle aspiration or biopsy of the lump, because pathological diagnosis is the gold standard for breast cancer diagnosis. After the pathological diagnosis is made, comprehensive treatment can be performed.
