Women suffering from painful but benign uterine fibroid tumors may have a noninvasive source of long-term relief. A new study led by the Mayo Clinic found that an outpatient treatment using high-intensity ultrasound can eliminate growths and keep them from returning for extended periods. The procedure leaves the uterus intact, so it is less traumatic than a hysterectomy — though only that more invasive procedure is known to eliminate tumors permanently.
