Underarm growth of paratits, which is also a common benign disease in women. For patients with small breasts, no clinical symptoms or relatively mild clinical symptoms, conservative treatment is generally considered, and regular ultrasound follow-up observation. At the same time, we should pay attention to the regularity of daily life, avoid tension and anxiety, maintain a relaxed mood, avoid eating high-calorie and exogenous hormone-containing foods, such as fried, hamburger, cola, coffee, strong tea and so on. In addition, if the paratesticular breasts are large, or if there are repeated episodes of obvious pain, affecting life or study, or if the paratesticular glands are likely to become cancerous, timely surgical treatment should be considered. For benign lesions, surgical excision under general anesthesia is recommended. Due to the special location of the axilla, after removing the paratesticular glands, drainage strips or tubes should be placed, and local elastic bandages should be applied to prevent the accumulation of fluid in the axilla. For malignant patients, radical resection should be considered and axillary lymph nodes should be cleared.
