What is the most common type of breast cancer?

Inflammatory breast

cancer is characterized by marked congestion, edema, acute inflammatory changes, and marked tenderness of the breast. This type of breast cancer is prone to axillary lymph node metastasis and even distant organ metastasis. Clinically, it is basically incurable and often recurs quickly after surgery.

2. Triple negative breast

cancer is a type of breast cancer in which estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (Her-2) are all negative in the cancer tissue. This type of breast cancer usually has a higher degree of malignancy and is more prone to recurrence and metastasis. The survival period of patients is relatively short, and patients can usually only be treated with chemotherapy after surgery and in the late stage, and there is no opportunity for targeted drug therapy or endocrine therapy.
