[Alterations in blood flow as a diagnostic criteria for breast cancer].

The article is dedicated to one of the challenging problems, i. e., diagnosis of breast cancer by the findings of ultrasonographic Doppler examination in women with endured augmentation mammoplasty performed by means of inserting gel implants. Special attention is paid to diagnosis of small tumours (less than 1.5 cm in size) and to differential diagnosis of malignant and benign neoplasms of the mammary gland with complications of gel plasty. The use of Doppler ultrasonography made it possible to increase the accuracy of ultrasonographic examination in diagnosis of breast cancer by 4.5 %. A highly specific sign of breast cancer, amounting to as high as 98.2 %, is local enhancement of the vascular picture within the zone of the growing tumour, including in women having sustained augmentation mammoplasty.
