Breast cancer is often referred to as the “pink killer”, and its incidence rate ranks first among female malignancies. Breast cancer is classified into non-invasive cancer, invasive cancer, and other rare cancers according to the type of disease. Non-specific invasive breast cancer is a type of invasive cancer, which has a poorer and more serious prognosis than non-invasive cancer. Non-specific invasive breast cancer is the most common type of breast cancer, including invasive ductal carcinoma, invasive lobular carcinoma, sclerosing carcinoma, and simple carcinoma with a low degree of differentiation. The cancer cells infiltrate and invade the surrounding tissues extensively, and are prone to metastasis, invading the lungs, bones, and the liver. In addition, non-specific invasive breast cancer is prone to recurrence after treatment, and requires adjuvant chemotherapy, radiotherapy or endocrine therapy after surgery, so the prognosis is worse than other types of breast cancer. If non-specific invasive breast cancer is detected early, through radical breast cancer surgery, combined with radiotherapy, chemotherapy and endocrine targeted therapy after surgery, the survival rate and cure rate after surgery can be improved; if it is detected late, with late pathological stage or metastasis from other parts, this situation is more serious, and the five-year survival rate is not very high with the application of targeted therapy drugs and endocrine therapy, so non-specific invasive breast cancer Therefore, early detection, early diagnosis and early treatment are necessary.
