[Analysis of hormone profile in women during the pre- and postmenopausal period using hormone replacement therapy, and analysis of the mammography image in these women]. / Analiza profilu hormonalnego u kobiet w okresie przed- i pomenopauzalnym stosujacych hormonalna terapie zastepcza, oraz analiza obrazu mammograficznego u tych kobiet.

The hormonal profile and mammography results were analysed in 120 women in premenopause (group A) and 130 in postmenopausal period (group B). The analysis developed biphasic menstrual cycle, with high progesterone levels in the second cycle's period in 57 subjects (group A--mean P concentration--53.7 nmol/ml), and elevated E2 levels in monophasic cycle in 63 subjects (group A2--man E2 205.4 pg/dl). In case of post-menopausal women mean E2 level during therapy was 104.6 pg/dl. In examined group 8 subject have been undergoing hormonal replacement therapy for 1-3 years, 30 of them for 5 years, 20 more than 5 years. In mammography in one case from group A1 with high progesterone concentration abnormally opaqueness has been observed. Histological examination confirmed incidence of cancer cells. No other changes have been observed. High serum progesterone concentration in pre-menopausal women increase risk of cancer.

[Evaluation of the usefulness of stereotactic aspiration fine needle biopsy for breast neoplasm diagnosis in the preclinical stages]. / Ocena przydatnosci biopsji aspiracyjnej cienkoiglowej stereotaktycznej w rozpoznawaniu przedklinicznych postaci raka sutka.

Out of 6000 mammographies performed in the years 1991-1992, 61 patients have been qualified to stereotactic fine needle biopsies. Finally 50 stereotactic biopsies have been performed on 37 patients. In 6 cases (12%) cancer has been recognized. Stereotactic biopsy allows to recognize cancer in preclinical stages. In comparison with the surgical this method is less stressing for the patients and cheaper.

[Mammography or ultrasound in the breast cancer diagnosis]. / Mammografia czy ultrasonografia w diagnostyce raka sutka.

Indications to ultrasound examination and mammography are discussed in this article. Ultrasound is useful in women younger than 35 and mammography on the contrary after this age. As far as screening is concerned obly mammography is a proper tool for recognition.

[Reduction of radiation dosage in mammography by using film intensifying foil systems in Poland]. / Redukcja dawki promieniowania w mammografii przez zastosowanie systemu film-folie wzmacniajace w warunkach krajowych.

In order to assess possibility of radiation dose reduction during mammography at direct film radiation, a comparative studies have been carried out. The studies involved Roentgen XT-2 film without intensifying foil compared with Mammoray MR-3 (Agfa Gevaert), Ortho M-MO-1 (Kodak) in the original cassettes, and Fluorfilm TK-1 (WZF Foton) with foils Min.-R. Film-intensifying foil systems are four and six times more sensitive than Rentgen XT-2 film. Sensitometric and diagnostic properties of Fluorofilm TK-1 are comparable with Mammoray MR-3 film. Therefore, films Rentgen XT-2 which are presently used in mammography should be replaced with Fluorofilm TK-1 with the intensifying foils.
