What kind of disease is breast fibroadenoma and can it become malignant? Fibroadenoma is the most common benign tumor of female breast, accounting for about 75% of benign breast tumors. Its occurrence and development are closely related to estrogen stimulation, so it is rare before menstruation or after menopause. Fibroadenoma of the breast is usually found in the upper outer part of the breast, and it mostly appears as a round lump with very clear borders and smooth surface, which can be easily pushed in the breast. Other than the lump, the patient does not feel anything else. The lump usually grows slowly and can remain unchanged for many years. It is generally believed that the chance of malignancy in breast fibroadenoma is very low, but malignancy often occurs during pregnancy and lactation, or in older cases with a longer history of disease. Breast fibroadenoma consists of both epithelial and fibrous tissues, and malignant changes in the epithelial tissue are called carcinoma, while malignant changes in the fibrous tissue develop into sarcoma. The young patients, especially unmarried women, do not have to worry too much about breast fibroadenoma, as the malignancy rate of this disease is extremely low for them. What is the age of breast fibroadenoma? Breast fibroadenoma is different from breast cancer in that breast cancer has a high incidence after the age of 40, while breast fibroadenoma can also develop after the age of 40, but it is common in young women aged 18-35. This is why we often see girls in their early twenties in our clinics, some of whom have just joined the workforce and some of whom are still in school. The young age of onset is one of the characteristics of this disease. Can oral medication cure fibroadenoma of the breast? Many patients who discover fibroadenoma of the breast look to medication. It is common to see patients who want to take oral Chinese medicine to treat fibroadenoma of the breast. The current view is that Chinese medicine treatment can inhibit the recurrence and multiplication of fibroadenoma, and the growth of fibroadenoma that proliferates vigorously. However, it is difficult to cure fibroadenoma with an intact envelope and a diameter of more than 1 cm by oral medication. 4. Is surgery always necessary? Research on benign tumors is not as intensive as that on breast cancer, and there is a lack of well-designed, randomized, double-blind clinical trials and articles with a high level of evidence. Most of the high evidence levels retrieved from the current literature are grade 2 and below. According to the literature and most expert consensus, the indications for surgery are: 1) the patient has a strong intention to operate; 2) the mass is larger than 5 cm; 3) the tumor is actively proliferating (more than 20% increase in mass volume on six-month review) However, the prerequisite for non-surgical treatment is pathological clarification of breast fibroadenoma. Therefore, pathological support by puncture biopsy is needed before clinical observation is determined. V. When is surgery appropriate? 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. In fact, the timing of surgery varies from person to person. How to do the surgery? The traditional surgical method is to make an incision on the surface of the lump and remove the lump completely, which will leave surgical scars on the surface of the breast. Nowadays, many women are paying more and more attention to beauty and do not want to leave unsightly scars on their breasts. Minimally invasive rotary incision can be used to remove the tumor through an incision of about 3 mm, which can make the surgery of breast fibroadenoma almost “beautiful and scarless” with little trauma and fast recovery. However, patients need to communicate with the doctor about the specific surgery method, and the doctor will make a comprehensive decision based on the size and location of the tumor. 7. Will there be recurrence after surgery? Fibroadenoma is clinically cured when the lesion is completely removed by surgery. However, about 15% of fibroadenomas have a tendency of multiple recurrence, 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, medication can also be used. Traditional Chinese medicine is effective in preventing recurrence of fibroadenoma.
