TRACE-ELEMENT CONTENT IN BREASTS WITH FIBROCYSTIC DISEASE

The trace elements antimony, bromine, cesium, cobalt, iron, rubidium, scandium, strontium and zinc were determined by instrumental neutron a ctivation analysis in breast tissue samples with fibrocystic disease a nd in samples with fibroadenoma tumors. The histological lesions of ea ch breast sample with fibrocystic disease were recorded, and a statist ical analysis of the lesions in combination with the determined trace elements was carried out. The results showed that the element mean val ues in fibroadenoma tumors are higher than those of fibrocystic diseas e. Some other remarkable results of statistical examination are also p resented.
