A Single-center, Prospective Clinical Study of High-intensity Focused Ultrasound Tumor Treatment System(Super Knife) in the Treatment of Breast Cancer
Breast cancer is the most common cancer diagnosed among women and is the second leading cause of cancer death among women after lung cancer. The treatment methods of breast cancer include surgery, chemotherapy, radiotherapy and so on. The investigators discover a High-intensity focused ultrasound therapy to treat breast tumor, which is a non-invasive method.
