Description of the examination
Mammography is a basic radiological examination of breast gland. It allows to early diagnose nodules of 0.5 cm diameter and the so called asymptomatic lesions. Breast examination by hand allows to detect tumours of over 1 cm in diameter. Diagnostic efficiency of mammography together with clinical examination by hand is valued on the level of 80-97%. It is particularly useful in screening tests. Apart from that mammography enables taking samples for microscopic examination, proper direction of a biopsy, intra-operative examination of resectioned material, objective chemotherapy and/or radiotherapy control in case of breast cancer.
