Brief summary
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.
Interventions
All participants will be randomly divided into groups A and B. Participants in group A will receive a high-intensity focused ultrasound tumor treatment (Super Knife) once, and participants in group B will receive treatment twice (4 weeks, one cycle).. Breast cancer surgery was performed at 3 months ± 1 week after the Super Knife treatment.
