Breast cancer is the most common cause of cancer in women globally. It has now surpassed lung cancer which was previously the first cause of cancer incidence globally. In India, breast cancer is ranked number one overall and among females. The FNAC Yokohama reporting system and BIRADS scoring system are good methods to detect any breast abnormality. Both in conjucation aid in identifying prognostically relavant diagnostic categories and thereby helping in multidisplinary management of breast lesions. This study will substantiate the role of FNAC and utility of IAC Yokhama in evaluation of breast lesions. We are doing this study to evaluate FNAC of breast lesions using Yokohama classification and its correlation with BIRAD System. Patient having breast lump clinically and who underwent FNAC and ultrasonography will be included after obtaining informed written consent. Patient confidentiality will be ensured by deidentifying data and patient will be given a unique code in numbers. Other relevant history, clinical findings will be collected from requisition form. The breast lump will be reported on USG according to BIRADS categories as suggested by American College of Radiology (ACR) and known as ACR BIRADS.
