Certain investigations on the Methods involved in computer aided Detection of breast cancer

Abstract

Breast cancer is a major killer disease for women and men It can newlinebe treated and controlled only if it is detected at its earlier stage Early newlinedetection can be achieved by the help of computer aided detection methods newlineComputer aided detection acts as second reader for radiologist to conclude the newlinestage and treatment options for breast cancer The computer aided detection newlineapproach uses mammogram image as input observed from the suspected newlinehuman breast Many computer aided detection systems have been designed newlineand tested by the researchers for the effective detection of breast cancer newlineHowever the detection efficiency is still needs improvement From the newlinedetailed study on previous researches, it is found there is no system newlineproducing 100 accuracy because of one or more reasons Absence of newlineeffective preprocessing and segmentation methods are most discussed reasons newlinethat obstruct the detection accuracy of computer aided detection method newlineClusters of microcalcifications, masses and architectural distortions newlineare some of the important signs of breast cancer that radiologists look from newlinedigital mammogram image The nature of breast region affects the detection newlineof these signs from a digital mammogram The wrong detection of breast newlinecancer signs will increase the risk and reduce the accuracy of the system To newlineperform perfect detection newline newline
