Carcinoma of breast is the second most common cancer among women next to uterine cervical cancer in Bangladesh. It was well established that 5 years survival rates greatly vary among the different stages of carcinoma of breast disease. The study was carried out to see the stages of presentation of carcinoma of breast patient to a tertiary level hospital attended first time for medical help as well as to find out the factors responsible for the late (advanced) stage presentation. This descriptive type of cross sectional study was carried out in the department of surgery, Mymensingh Medical College and Hospital (MMCH) during the period of May 2010 to April 2011. A total of 110 cases admitted with carcinoma breast diagnosed by means of FNAC positive or suspicious findings were selected purposively during the study period. Patients were staged initially according to the TNM staging system by through clinical examination as well as final clinicopathological stages were done after histopathological examination of the resected specimen (breast with or without axillary lymphnode) in resectable cases. Among the advanced stage presentation, attempts were made to find out the factors responsible for advanced stage of the disease. The results showed that carcinoma of breast predominantly a disease of female and comparatively younger age group 40-49 years affected mostly in 40.9% cases with a mean age of 44.02±10.32 years. Premenopausal lady mostly affected in 63.6% cases. Majority of patients presented in advanced stage of the disease in 62.8% cases. Multiple factors were observed responsible for the advanced stage of the disease - among them delay in hospital presentation, poor socioeconomic condition and illiteracy have found to be associated which were statistically significant (p<0.001). It was needed for mass awareness program against the breast cancer in our society. Necessary steps should be taken for the initiation of breast self examination (BSE) to patients and clinical breast examination (CBE) to health care providers.
