Abstract The Image pre-processing plays an important role in Breast cancer detection. Mammography images are usually preferred for breast cancer detection analysis. Images should be pre-processed to remove the noise, preserve the edges of an image, and enhance the image quality for carrying out further image analysis. The filtering techniques available for image pre-processing are an average filter, adaptive median filter, median filter. This paper provides various pre-processing techniques for breast cancer detection using noisy MIAS images. The pre-processed results are evaluated by feature extraction. Keywords: Breast cancer, Pre-processing, Mammography, MIAS Data, Median Filter ________________________________________________________________________________________________________ I.

INTRODUCTION

Breast Cancer cells are characterized by unrestrained division principal to abnormal growth & the aptitude of these cells to arrive in normal tissue locally or to spread through the body this evolution called metastasis. Breast cancer is a type of cancer originating from breast tissue, commonly from. Hence early detection of breast cancer is essential in effective treatment and in reducing the number of deaths caused by breast cancer. There are mainly two types of breast cancer, a ductal carcinoma is the most common cancer where cancer begins in the milk duct and the second is cancer that begins in the lobules are called lobular carcinoma[1].The Image processing plays an important role in cancer detection. The image pre-processing is carried out by various filtering techniques to enhance the image quality, preserves the edges and remove the noise present in the image database .The pre-processing produce better quality image which is used for feature extraction for further analysis. Images and Database The Mammography Image Analysis Society (MIAS) is an organization of UK research groups which have produced a digital mammography database Images are in gray scale file format (PGM – Portable Gray Map) .The original MIAS Database is digitized at 50 micron pixel edge and every image is 1024 pixels x 1024 pixels known as the mini-MIAS database and .The Selected mini-MIAS database as it contains abnormalities in each mammographic image . II. PRE-PROCESSING The purpose of the pre-processing stage is to improve quality of the image, remove background noise and pictorial muscles present in the image. The pre-processed image is making ready for feature extraction process. The accuracy of cancer detection is improved after pre-processing of the image. The different filtering techniques which are used for pre-processing are as below:Median Filter It is a non- linear filter which is effective in removing the salt and pepper noise. The median inclines to keep the sharpness of an image.
