Breast fibroids of 3cm are not suitable for minimally invasive treatment. Minimally invasive treatment is based on the principle of shredding the breast mass through a 1cm scalpel and then aspirating it out of the body through a tunnel, with the advantage that the surgical incision is relatively small, about 5mm, but the lesion itself is more invasive. The surgical incision cannot be closed and pressure is applied to the incision to stop the bleeding. The intracutaneous suture is not too obvious for most patients and can achieve a better cosmetic effect, and the damage to the breast gland itself is relatively small, especially for women who are not breastfeeding, and can play a better role in protecting the breast gland.
