The prospective study, lasted from January 2010 to January 2015, covered the respondents treated for breast carcinoma. The respondents were divided into 2 groups. First group, group A (59 respondents), included the respondents where the tumour was found in diameter to 2 cm and were operated by breast-sparing surgery. Second group, group B (88 respondents), was consisted of respondents where the tumour was discovered in diameter over 2 cm and which breast amputated as part of a radical cancer surgery by Madden technique. The aim of this study is to analyse the effects of surgical treatment of breast carcinoma with different diameter and influence of tumour diameter on treatment outcome. The parameters for comparison of results were the number of relapses, the time elapsed from surgery to recurrence and treatment outcome. There were no significant differences between the two groups regarding the motives for attending breast examination. The incidence of carcinoma in the left or right breast also showed no statistical difference. It was found that the most common breast cancer is in women age between 50 and 70. It has been shown that breast carcinoma with diameter over 2 cm was significantly more frequent in women age of 71 to 80. Recurrent disease was registered in 3 cases in respondents from group A. Recurrence in group B was not registered. Lethal outcome was observed in group B in 4 cases, and in group A in 1 case, which proved to be statistically different.

Introduction: Timely diagnosis is a prerequisite for the successful treatment of malignant skin tumors. Late diagnosis leads a patient into a situation of losing valuable time and chance for cure. Material and methods: A prospective study was conducted from February 2006 until August 2011 which analyzed the reasons that led to establishing the diagnosis of malignant skin tumors in 220 patients. Patients were divided into two groups: Group A (102 patients), patients with diagnosed melanoma, and group B (118 patients) of patients suffering from basocellular (BCC) and planocellular cell (PCC) skin cancer. Parameters for comparison of analysis results were the reasons for coming to examination and reasons for not coming to the examination, because of which skin cancers were not diagnosed in time. Goal: To determine the factors that influences the establishment of late diagnosis and treatment of skin tumors. Results: It was confirmed that the prejudices of patients that tumors of the skin „should not be operated because it is dangerous“ is the main reason for late diagnosis. At the same time it is confirmed that the belief that it is unnecessary to operate congenital changes of the skin is the second most important reason for delayed diagnosis of malignant skin tumors.
