The invention provides a cervical carcinoma and uterus cancer detection method and a system thereof, which relate to the fields of biological and microbiological analysis detection. The method comprises the following steps: obtaining a microscopic image of vaginal secretion; performing edge detection, filling up an internal gas of the edge to form a complete exfoliative cell shape; obtaining a microscopic image of exfoliative cell, performing edge detection to obtain cell nucleus; calculating an area difference and curvature of the exfoliative cell to determine the result as cervical carcinomaand uterus cancer; calculating the ovality of the exfoliative cell, and when the ovality of the exfoliative cell is lower than a first set value, determining the result as precancerous lesions of cervical carcinoma and uterus cancer; calculating a ratio of an area of the exfoliative cell nucleus to the area of the exfoliative cell, and when the ratio of the area of the exfoliative cell nucleus tothe area of the exfoliative cell is higher than a second set value, determining the result as an early stage of precancerous lesions of cervical carcinoma and uterus cancer. Compared with the prior art, the method has the advantages that the measurement time is short, the complex processes such as dyeing culture cannot be required, and the process is simple and reliable.
