Minimally Invasive Treatment of Breast Fibroids Breast fibroids are most common in young women and surgical treatment remains the mainstay of treatment. Conventional surgery has the disadvantages of scarring and traumatizing the breast tissue. Mammotomer rotational excision is a more ideal surgical method to treat benign breast tumors. The tumor can be clearly removed under ultrasound guidance, the incision is chosen in the armpit or hidden area, the incision is only 3-4 mm, which preserves the perfect shape of the breast, no suture, no scar, little pain and quick recovery.
