The cancer which occurs when breast cells begin to grow in an abnormal manner is known as breast cancer. Some of the major symptoms of breast cancer are a lump in the breast or in an armpit, inverted nipple, persistent pain in the breast or armpits, and discharge from the nipple. It generally begins in the inner lining of the milk ducts and then spreads to other body parts. The two major types of breast cancer are ductal carcinoma and lobular carcinoma. It can be diagnosed through biopsy and imaging tests. Determining the stage of the cancer is one of the most important aspects of diagnosis. This book unravels the recent studies on breast cancer. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in it. This book aims to equip students and experts with the advanced topics and upcoming concepts in this area.
