Infiltrative breast cancer is a malignancy in which cancer cells have penetrated the basement membrane of the ducts or lobular alveoli of the breast and invaded the interstitium.
The vast majority of invasive breast cancers are adenocarcinomas that originate in the parenchymal epithelial cells of the breast, particularly in the lobular units of the terminal ducts of the breast.
Invasive breast cancers have many morphologic phenotypes and are clearly classified into different histopathologic types based on their specific prognostic or clinical features.
Several studies have noted that tumors with high histologic grading respond better to certain chemotherapy regimens than those with low histologic grading. Sometimes cancerous tissue invading peripheral nerves is found in invasive breast cancer, but it is not an independent prognostic guiding factor.
There are six separate treatments for breast cancer: surgery, radiation therapy, endocrine therapy, chemotherapy, immunotherapy, and Chinese herbal medicine, which are still effectively used in clinical practice today. The treatment of breast cancer should be formulated according to the patient’s condition to avoid unnecessary complications as much as possible, and a reasonable and effective treatment for breast cancer is also the key to improve the cure rate of patients.
