The development of modern scientific instruments has provided a good technical guarantee for minimally invasive medical treatment. In the past, all tumors of the breast had to be surgically removed, which dealt a blow to the self-esteem and self-confidence of women who love beauty. The modern civilized lifestyle has led to an increasing incidence of breast enlargement and mammary adenoma, which has reached about 9.3% among women of childbearing age, with a younger age of onset and many unmarried women suffering from mammary fibroadenoma. Although mammary fibroadenoma is a benign tumor, it has a malignant rate of 0.038-0.12%, so large and definite mammary fibroadenoma needs to be treated. In the past, treatment was based on adenoma excision, and even minimally invasive surgery has scars and an impact on the appearance of the breast. In ultrasound-guided percutaneous microwave ablation for uterine fibroids and uterine adenomyosis, the percutaneous microwave ablation of breast adenomas, carried out on the basis of working experience, uses tiny microwave electrodes to inactivate the tumor in situ in a very short time, so that it loses the possibility of malignant transformation and shrinks, with no change in breast appearance and function. The treatment is painless for the patient.
