Breast cancer is a disease characterized by the uncontrolled growth of altered breast cells,leading to tumor formation. If left untreated, these tumors can metastasize-spread to other parts of the body-and become life-threatening. Cancer typically originates in the milk ducts or lobules of the breast. It is categorized into stages, with Stage 0 (in situ) being non-life-threatening and detectable early.As cancer progresses, it can invade surrounding breast tissue, causing palpable nodules or thickening. Invasive cancers have the potential to spread to lymph nodes and distant organs (metastasis), which can be fatal.
