It originates from the epithelium and mesenchyme of the breast lobules and contains both epithelial and mesenchymal fiber components.
The exact cause of fibroadenoma is still inconclusive in medical research. It is widely believed that the occurrence of fibroadenoma is related to the endocrine hormonal imbalance of lesbians, especially the changes of estrogen and progesterone.
It occurs in young women, most often around the age of 30.
The main manifestation is a painless lump found by chance, with few accompanying symptoms.
V. There are three types of fibroadenoma.
1.Mixed type
2.Adolescent type
3, giant fibroadenoma.
Fibroadenoma has a very low chance of malignancy, mainly mixed type adenoma, combined with a family history of breast cancer, with a chance of sarcoma transformation. Adolescent type and giant fibroadenoma basically will not become malignant.
Some studies have shown that a small percentage of fibroadenomas can disappear on their own.
The examination of fibroadenoma includes physical examination, ultrasonography, mammography, puncture or excisional biopsy, among which ultrasonography and biopsy are accurate.
For young women under 40 years old, if the fibroadenoma is clearer by physical examination and ultrasound, it can be observed in smaller cases, and if you can touch the tumor yourself, you can check yourself once a month to observe whether the tumor grows faster and whether there is any change in shape. If there is not much change, go to the hospital for review once every six months to a year.
X. The following cases.
1.Age over 40 years old.
2.Large tumor (my personal standard is more than 3cm).
3.The tumor is growing fast.
4.The patient himself is nervous about the tumor in the breast.
5.Family history of breast cancer.
6.Women of childbearing age who are preparing to get pregnant.
7.The possibility of fibroadenoma is considered by physical examination and auxiliary examination, but there are doubts. I suggest the patient to be treated actively.
11.The treatment of fibroadenoma of the breast is mainly surgical.
Surgery is divided into two ways.
1, traditional open surgery to remove. The advantages are that the surgery is performed under direct vision, the efficacy is intuitive, the size of the tumor is not limited, and there are few complications.
2. Minimally invasive surgery by McMurdo. The advantage is that the scar is not obvious, the gland is less traumatic, especially suitable for patients with multiple, small tumors, the disadvantage is that the tumor is larger, more than 3.5cm size, not suitable for minimally invasive, and secondly, due to the operator’s technology, the tumor is not completely removed, postoperative mu
In addition to surgery, there are also ablation therapy, including cryotherapy, radiofrequency ablation, laser ablation, microwave therapy, etc.
Thirteen, tumors in the breast consider fibroadenoma, but there are doubts, or the diagnosis is clearer but the patient is worried, however, the patient is afraid of surgery, or time, work and other conditions temporarily do not allow, you can consider puncture biopsy, if it is clear that it is fibroadenoma, observation, regular review.
Fourteen, about the post-operative recurrence. Fibroadenoma is a benign tumor and will not recur after removal, but other glandular tissues will grow again. Is it better to remove the existing tumor, grow it again and then cut it again? Or should we observe, review regularly, and cut together when more growth occurs? This is a problem that many patients are struggling with. My opinion is to analyze the specific problems according to the several cases I mentioned.
Fifteen, other treatments, such as Chinese herbal medicine, local drug injection, physiotherapy, etc., I think are not very meaningful.
