210 patients hospitalized in the Bacău County Emergency Hospital, Oncology department, were investigated, in which the CA 15-3 marker was determined and 73 patients with the CEA marker. The biological material consisted of peripheral blood collected from these patients. In the test performed with the CA 15-3 marker, 59% of the patients have marker values within normal limits, which means that following the surgical and medical treatment the patients' evolution is good, while 41% of the patients have marker values above the limits admitted, and therefore the evolution of the patients is not favorable, and the treatment must be improved. In the test performed with the CEA marker, 90% of the patients have marker values within the reference limits, so following the applied treatment the patient's evolution is good, while 10% of the patients have marker values outside the reference limits, and therefore the patient's evolution is not favorable, and the treatment must be changed. In the present study, the minimum age at which the form of breast cancer (mammary adenoma) was identified was in a 9-month-old girl.
