Invasive breast cancer refers to a type of malignant tumor from the ductal epithelial cells, and the 5-year survival rate of early invasive breast cancer can reach about 99%. Invasive breast cancer is a malignant tumor located in the breast, which means that the cancer cells have penetrated the basement membrane of the ducts or lobular alveoli and gradually invaded the interstitium. Invasive breast has no specific manifestations, and its main symptoms include breast lumps, nipple discharge, nipple and areola abnormalities, and enlarged axillary lymph nodes. Current treatments for invasive breast cancer include surgical treatment, radiation therapy, and drug treatment modalities. The prognosis of invasive breast cancer after treatment varies with different stages, and its 5-year survival rate is about 95% according to the stage: stage I; stage IIA is about 85%; stage IIB is about 70%; stage IIIA is about 52%; stage IIIB has a 5-year survival rate of about 48%; and stage IV is about 18%. It is recommended that patients actively seek medical treatment, which can help improve the prognosis and prolong the survival period.
