[Breast conserving treatment in patients with early detection of breast cancer]

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.

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.
