📖 Introduction
Breast cancer is a disease in which abnormal cells in the breast grow uncontrollably and may form a tumour. It often begins in the milk ducts or lobules and may spread to nearby tissue, lymph nodes, and eventually other organs if not treated early.
Breast cancer is the most commonly diagnosed cancer in women in 164 countries and caused an estimated 694,000 deaths globally in 2024.
