Non-specific invasive breast cancer is a malignant tumor that cannot be completely cured and may recur. In the treatment of non-specific invasive breast cancer, if the tumor is in the early stage according to the TNM stage of the tumor, it is possible to prolong the survival period by surgically removing the mass or even the whole breast. Cure of the tumor refers to patients whose tumors do not recur or metastasize for 5 years. But some patients will still recur after 10 and 20 years. In case of non-specific invasive breast cancer that has metastasized, although it cannot be cured under the current medical conditions, active treatment can prolong the survival period and improve the quality of survival. Most of the breast cancers have a lifelong risk of recurrence, and the patients should insist on regular rechecking. Patients should insist on regular rechecks and seek medical treatment when metastatic symptoms are found. It is recommended that breast cancer patients go to regular hospitals in time and receive treatment according to medical advice.
