Optical ultrasonic breast cancer detector and detection method thereof

According to the technical scheme, the optical ultrasonic breast cancer detector is characterized in that the optical ultrasonic breast cancer detector comprises a barrel, a photoacoustic detection module is arranged in the barrel, the photoacoustic detection module rotates in the circumferential direction of the inner wall of the barrel through a driving mechanism, and the photoacoustic detection module is used for irradiating parallel laser to breasts; and an ultrasonic signal generated after the human mammary gland absorbs the light energy is received. The optical ultrasonic breast cancer detector provided by the invention is composed of the cylinder, the photoacoustic detection module and the driving mechanism, the driving mechanism drives the photoacoustic detection module to scan the breast of a patient in all directions, and the arranged photoacoustic detection module emits parallel laser to the breast of the patient; the laser energy received by the breasts of the patient is more uniform, the photoaco
