Abstract

Management of breast cancer in elder patients is challenging due to a lack of good quality evidence regarding the role of adjuvant chemotherapy. Mammograms can depict most of the significant changes of breast disease. The primary radiographic signs of breast cancer are masses (its density, site, shape, borders), spicular lesions and calcification content. The basic idea is to convert the mammogram image and convert into 3-D matrix. Obtained matrix is used to convert the mammogram into binary image. Several techniques like detecting cell, filling gaps, dilating gaps, removing border, smoothing the objects, finding structures & extracting large objects have been used. Finally finding the granulometry of tissues in an Image without explicitly segmenting (detecting) each object. Compared to existing multiscale enhancement approaches, images processed with this method appear more familiar to radiologists and naturally close to the original mammogram.

Background

Cancer continues to be a significant public health problem in the world. Elderly population of the society has this problem and it is prevalent all over the world. The proposed group of diseases is both, a medical as well as a social challenge and its management still needs to be improved markedly.

Cancer is a group of diseases that cause cells in the body to change and grow out of control. Most types of cancer cells eventually form a lump or masses called a tumor, and are named after the part of the body where the tumor originates. Breast cancer begins in breast tissue, it is the uncontrolled growth of abnormal cells in the breast. As with other forms of cancer, breast cancer is considered to be a result of malfunctioning Deoxyribonucleic Acid DNA due to damage or inherited mutation. It is a disease that typically develops in women; however, it is also possible, although rare, for breast cancer to develop in men as mentioned by Biganzoli L et al. (2004).
