# Breast Cancer Detection Breast Cancer Detection Using Machine Learning # What is Breast Cancer? Cancer occurs when changes called mutations take place in genes that regulate cell growth. The mutations let the cells divide and multiply in an uncontrolled, chaotic way. The cells keep on proliferating, producing copies that get progressively more abnormal. In most cases, the cell copies eventually end up forming a tumor. Breast cancer occurs when a malignant (cancerous) tumor originates in the breast. As breast cancer tumors mature, they may metastasize (spread) to other parts of the body. The primary route of metastasis is the lymphatic system which, ironically enough, is also the body's primary system for producing and transporting white blood cells and other cancer-fighting immune system cells throughout the body. Metastasized cancer cells that aren't destroyed by the lymphatic system's white blood cells move through the lymphatic vessels and settle in remote body locations, forming new tumors and perpetuating the disease process. Breast cancer is not just a woman's disease. It is quite possible for men to get breast cancer, although it occurs less frequently in men than in women. Our discussion will focus primarily on breast cancer as it relates to women but it should be noted that much of the information is also applicable for men. # Facts And Figures Breast cancer is the most commonly occurring cancer in women and the second most common cancer overall. There were over 2 million new cases in 2018. **Prevalence** 1) Asia Percentage of world population: 59 Percentage of new breast cancer cases: 39 Percentage of breast cancer deaths: 44 2) Africa Percentage of world population: 15 Percentage of new breast cancer cases: 8 Percentage of breast cancer deaths: 12 3) U.S. and Canada Percentage of world population: 5 Percentage of new breast cancer cases: 15 Percentage of breast cancer deaths: 9 (Data from Global Cancer Facts and Figures, 3rd Edition, pag …
