The most commonly used technique for early detection of breast cancer is X-ray mammography. However, it causes ionizing radiation. Therefore, the microwave mammography has been developed. In our work, a CMOS digital breast cancer detection system has been developed. With the bandpass filter, the noise in the subtracted signal can be suppressed. The spikes are eliminated and the integration unbalance is mitigated. The SCR and SMR of the confocal image are improved after bandpass filtering
