Invasive breast cancer is the most common tumor in women, accounting for 22% of all malignant tumors in females. Invasive breast cancer refers to a malignant tumor where cancer cells have broken through the basement membrane of the breast ducts or lobular alveoli and invaded the interstitium. The vast majority of invasive breast cancers are adenocarcinomas, originating from the epithelial cells of the breast parenchyma, especially from the terminal duct lobular units. Its characteristics include the tumor's infiltration into adjacent tissues and a marked tendency for distant metastasis.
