Fibroadenoma of the breast is the most common benign tumor of the female breast, accounting for about 75% of benign tumors of the breast. Unlike breast cancer, which has a high incidence after the age of 45, fibroadenoma of the breast also develops after the age of 45, but it is common in young women aged 18 to 35, and a younger age of onset is one of the characteristics of this disease. The occurrence and development of mammary fibroadenoma is closely related to the stimulation of estrogen, so it is rare before menstruation or after menopause. It occurs in the upper outer part of the breast and presents as a round lump with very clear borders and a smooth surface, which can be easily pushed within the breast. The lump is smooth and can be easily pushed within the breast. The patient does not feel anything else. These lumps grow slowly and can remain unchanged for many years. The chance of malignancy in mammary fibroadenoma is very low. If malignancy occurs, it is common in patients who are pregnant and breastfeeding, or in patients who are older and have a longer history of disease. Breast fibroadenoma consists of both epithelial tissue and fibrous tissue. Malignant changes in the epithelial tissue are called carcinoma, while malignant changes in the fibrous tissue develop into sarcoma. Young patients, especially unmarried women, do not have to worry too much about fibroadenoma of the breast. To further support the diagnosis, it is recommended to do ultrasound examination to understand the local blood flow, whether the envelope is intact, and whether the boundary is clear; patients under 30 years old should not do mammography unless they suspect malignancy, because mammography is a radiological examination, and young women have more benign lesions and dense breast glands. It has little diagnostic value and is harmful to the body. Once a breast fibroadenoma is formed, especially when ultrasound shows the presence of an intact envelope, relying on medication can soften the mass and make it smaller, but it cannot be completely cured. The current consensus is that only surgical excision can completely remove fibroadenoma from the breast. When is the right time to have surgery? Many patients find breast lumps unintentionally, when they still have a lot of school and work to arrange. Some patients think that since breast fibroadenoma is a benign tumor, it doesn’t matter how early or late the treatment is; others think the tumor should be removed early and feel anxious because they can’t take time off work temporarily. As a matter of fact, the timing of surgery is going to be different from person to person. When breast fibroadenoma is found, patients are recommended to have surgery to remove it. Firstly, the current diagnosis is only a clinical diagnosis without pathological confirmation, so the accuracy rate is not 100%. If the conditions allow, surgery can be performed as soon as possible. However, breast fibroadenoma does not require immediate surgery once it is detected. Unlike breast cancer, which is medically recommended to be operated on for a limited period of time, surgery should not be delayed for too long due to the condition. Fibroadenoma of the breast, on the other hand, can be operated at an appropriate time. Patients who are temporarily unable or unwilling to undergo surgery for personal reasons are recommended to be observed regularly and reviewed once in 3 months. Those cases need to be treated by surgery as soon as possible If the following cases occur, patients are advised not to wait: firstly, the lump grows too fast, in this case the chance of tumor malignancy increases and delays the treatment time, the lump increases significantly and the surgery trauma is bound to increase; secondly, patients preparing for pregnancy, because pregnancy can stimulate the tumor to grow rapidly, it is better to remove it before pregnancy; thirdly, patients after 40 years old, so when Thirdly, patients after 40 years old, because the incidence of breast cancer increases, it is advisable to remove breast lumps as soon as possible. Fourthly, if the ultrasound shows that the tumor is rich in blood flow, it should be removed as early as possible. Surgery and scars Many women are afraid that surgery will leave unsightly scars on their breasts, and they reject it. In fact, many large hospitals have introduced minimally invasive techniques to remove breast fibroadenoma, using the McMurdo technology, which means that the tumor is removed through a large incision of about 3 mm, and the tumor, which is several centimeters in size, is cut open and removed in stages under direct vision, which can make breast fibroadenoma surgery almost “beautiful and scarless”, with little trauma and fast recovery. In primary hospitals, cosmetic incision sutures can also be used to reduce the formation of surgical scars, and the results are also very good. Post-surgical recurrence The fibroadenoma is cured when the lesion is completely removed. However, about 15% of fibroadenomas have a tendency to recur, and patients may have tumors in both breasts at the same time, or two or even more tumors in one breast, and tumors may appear in other parts of the body soon after this cure. However, recurrence of fibroadenoma is not due to surgical irritation. As a discovered breast fibroadenoma, it no longer exists once it has been surgically removed. Patients should be reviewed regularly after surgery and recurrence of tumor should be dealt with promptly. To prevent recurrence, it can also be treated with medication with certain efficacy.
