Breast cancer is one of the most common tumors faced by women worldwide, and is also the cancer with the highest incidence rate for women in China. Breast cancer screening is an important measure for early detection of breast cancer, early treatment, improvement of survival rate of breast cancer patients, reduction of mortality and reduction of medical cost, and is necessary for regular breast screening. At present, patients are usually detected by adopting modes of palpation imaging, breast molybdenum target X-ray imaging, ultrasonic imaging, optical imaging, nuclear Magnetic Resonance (MRI), near infrared ray breast scanning and the like, and because the devices for carrying out the detection are arranged in the hospital and doctor is necessary to participate in the execution, the patients need to go to the hospital to carry out breast screening, and the inconvenience leads the patients to miss the opportunity of early finding of illness state.
