Fibroadenoma of the breast is the most common type of benign tumor of the breast, which is more common in young women and less common in premenstrual and postmenopausal women. It is believed that it may be related to the relative or absolute increase in estrogen levels, over-sensitivity of breast tissue to estrogen, diet, genetics and other factors. The most common reason for a visit for breast fibroadenoma is the patient’s self-discovery of a breast lump. Most lumps occur in the upper outer quadrant of the breast and are often solitary, but may also occur bilaterally. They are mostly oval or round in shape, but may also appear lobulated or gourd-like in growth. How to diagnose breast fibroadenoma The diagnosis of breast fibroadenoma with typical physical signs and imaging manifestations is not difficult. In clinical work, in order to avoid missing diagnosis of malignant tumor, triple examination of breast lumps: clinical physical examination, imaging examination and puncture biopsy is often used abroad. However, because fine needle aspiration has a certain leakage rate, coupled with the fact that the age of onset of breast cancer in Chinese women is about 10 years earlier than that in European and American countries. Therefore, in domestic clinical work, women with obvious lumps found by physical examination can be followed up according to the patient’s wishes if the ultrasound or combined puncture examination is considered benign, but the patient must be informed that she must take a minimal risk of delaying the diagnosis and make a decision on the next step of treatment in combination with the patient’s wishes. If the puncture result is normal breast tissue or fatty tissue, the diagnosis should be considered unclear and another puncture may be performed. If it is still unclear, further surgical biopsy must be performed to clarify the diagnosis, and if the physician suspects that the mass has a malignant tendency during the clinical physical examination, early surgical excisional biopsy is advisable. Surgical incision selection for breast fibroids: Different surgical incisions are decided according to the different parts of the tumor. Tumors near the areola can be treated with a circular areolar arc incision and intradermal suture incision, so that the scar is not easily detectable after wound recovery. For tumors in the lower part of the breast, a curved incision can be made along the lower edge of the breast, so that the wound is more concealed. In young patients, if the tumor is less than 3cm, minimally invasive surgery such as McMurdo rotary incision can be performed. The operation is minimally invasive, usually a tiny incision of 5mm or so is made at the hidden part of the breast edge, leaving almost no scar after the operation. However, McMurdo’s minimally invasive rotational incision requires attention to the patient’s coagulation function, whether she is menstruating, breastfeeding or pregnant, and whether the mass is >3 cm (because it is not easy to remove completely). Smaller breasts and a mass too close to the skin or nipple or chest wall can also affect the resection results. For patients over 35 years of age, it is recommended that surgery be performed promptly after clinical physical examination, imaging, and puncture biopsy to clarify the diagnosis Surgery should be chosen to remove part of the gland surrounding the lump to prevent recurrence.
