One of the most valuable tools for the prevention of uterine cancer, the pap test is a quick and painless test that every woman between 25 and 65 should perform at least once every three years. The pap smear is a cytological screening tool (generalized diagnostic investigations), that is, it serves to analyze the cells taken through a sample of uterine mucosa, to verify any anomalies. The gynecologist is to determine which and how many diagnostic tests are advisable.
