[Ultrasound differentiation of fibroadenoma and diagnosis of minimal carcinoma of the breast].

The investigation was based on the ultrasound and mammographic examination of 630 patients with different patterns of fibroadenoma and 23--with carcinoma of the breast. Sonography should be carried out in step with menstrual cycle when diffuse hyperplasia of glandular tissue is registered. Minimal lobular cancers present most difficulties.

[Ultrasonography and differential diagnosis of breast cancer].

The echographic features of different neoplasms of the breast were studied in 449 patients. The most frequent-symptoms of carcinoma, fibroadenoma and cyst and their significance for differential diagnosis are discussed. A diagnostic procedure is suggested for use in ultrasonic examination of the breast.

[Comprehensive radiographic diagnosis of breast cancer].

The echographic and mammographic features of diagnosis neoplasms of the breast were studied in 447 patients. Shows its potentialities in the diagnosis. Supplementing each other, each technique yield the maximum intermation.

[Ultrasonography and mammography in breast cancer].

203 cases of breast pathology were examined using mammography and sonography, the latter procedure yielding, on the whole, more information. The sensitivities of both procedures in cases of breast cancer were 93.65 and 98.

[The morphological characteristics of primary breast cancers with different growth rates].

Morphologic peculiarities of primary breast cancer versus growth rate were studied in 46 cases. Growth rate (actual doubling time) was established by mammography carried out at certain time intervals. Morphologic investigation included assessment of tumor histology, degree of invasion, growth pattern, presence of pathologic mitoses, degree of blood vessel invasion, degree of necrosis, presence of microcalcinates, type of desmoplastic reaction, peculiarities of cell infiltration, background and regional lymph node reaction, and grade of malignancy.
