  ABSTRACT: There are several challenges in the diagnosis of breast cancer in young women. Special consideration must be given to the woman's fertility and body image issues, but the difficulty in distinguishing benign from malignant lesions in this group of patients still exists. The aim of our study was to show five cases of breast cancer in young women. Based on 5 cases of breast cancer in women younger than 25, several methods used in diagnosis in this group of patients were discussed. The role of USG and BAC was analyzed. Moreover, a significant role of RM and PET was emphasized. Diagnosing and treatment of young patients with breast cancer should be performed in specialized oncological centers experienced in dealing with breast cancer in very young women. 1. Because of the possibility of breast cancer in women under 25 years old, each case of breast tumor should be precisely diagnosed, especially by ultrasonography and biopsy (BAC) 2. Each case suspected of breast cancer in young women should be diagnosed in highly equipped and specialized medical center.

  ABSTRACT: Kujawsko-pomorskie province is a region with high morbidity and death-rate from breast cancer. One method of detected less advanced forms of breast cancer and increased number of patients with BCT having prophylactic medical examination. Design: The aim of the study was the treatment evaluation of patients with noninvasive and invasive cancer treated with BCT, screening-detected and non-screening detected. Prophylactic mammography for breast cancer was taken in three medical centers. First one so called "mobile" was localized in the health service center, second one in the bus with the mammography reaching distant areas and third one was performing examinations locally. There were 63401 people examined for breast cancer (age 35 -79), detected 288 breast cancers (0.54% of examined population). 260 of them were operated on. 1149 breast cancers were detected in non-screening group. The number of detected noninvasive cancers, their sizes and methods of treatment were analysed. Twelve of 260 (4,62%) cancers detected in screening patients were carcinoma noninvasive and 34 invasive cancers treated with BCT. In non-screening patients 20 carcinoma noninvasive and 104 invasive cancers were found and treated with BCT The number of patients with noninvasive and invasive cancers treated with BCT in prophylactic group is statistically higher. Sizes and clinical stages of malignant tumours detected in both groups were not different 1. Prophylactic breast cancer examinations increase the number of noninvasive cancers. 2. Breast cancer prophylactic examinations increase the number of patients treated with BCT.

  ABSTRACT: Prophylactic campaign against breast cancer wide spread by Regional Center of Oncology made significant influx of patients coming to our place and presenting less advanced stages of the mentioned disease. The aim of this work was estimate of BCT treatment standard for invasivum cancer and preinvasivunm breast cancer treatment standard which was adapted in RCO. Patients presenting unifocal invasive cancer smaller than 2 cm, stage No, where the minimal margin of more than 1 cm was possible to perform, were qualified to BCT. Minimal surgical border during tumorectomy was 1 cm. We were excluded patients with carcinoma lobulare and carcinoma mucinosum. During qualification to DCIS treatment standard first we must exclusion multifocalis cases based on Anderson classification and Falun consens. In the other cases we based on Van Nuys Prognostic Index (VNPI) considering the patient's age. We have 3 forms of treatment: simplex mastectomy, tumorectomy and tumorectomy with RTG-therapy. To BCT standard were qualified 52 patients. Schematically was attended 45 peoples. We had 5 patients which was attended based on preinvasivum breast cancer treatment standard. The size of breast cancer tumor at the patients which was attended based on BCT standard was 0,5-2 cm. 3 patients was disqualified from BCT because we found second breast cancer focus in histopathological material. We must widen surgical border post tumorectomy in 5 cases. Among 5 patients with preinvasivum cancer was 3 simplex mastectomy and 2 cases tumorectomy with RTG-therapy. In our opinion BCT treatment standard and breast preinvasivum cancer treatment standard should be using only in high specialty oncological center. It is a guaranty of right qualification and treatment for breast cancer patients.
