Diagnostics of dyshormonal mammary gland diseases with multifrequency electrical impedance mammography

Abstract

More than 34 000 new cases of breast cancer are registered annually in Russia with the patients age becoming significantly younger. 25% of women under thirty and 60% of those above forty are diagnosed as dyshormonal mammary glands (mastopathy) cases. Though mastopathy is not considered to be obligatory cancer prelude, breast cancer occurs 3 - 5 times more often in patients with diffuse dyshormonal noncancerous diseases of mammary glands and 30 - 40 times more often with nodular forms of mastopathy aggravated by proliferation of lactic gland epithelium [1]. This evidence has heightened the general interest in non-malignant growth opening the way to incidence reduction in breast cancer through effective curing of mastopathy. The existing methods of mastopathy diagnosis have certain applicability restrictions of both objective and subjective nature. The report presents main results of a comprehensive examination of 166 women (92 without breast pathology and 74 with mastopathy) with four methods: multifrequency electrical impedance mammography, ultrasonic investigation, x-ray mammography and puncture biopsy.
