There are several types of breast cancer

Breast cancer is divided into several types. In simple terms, it is generally divided into non-invasive cancer, early invasive cancer, non-special invasive cancer and special invasive cancer. Most are non-specific invasive cancers, which are generally considered to be carcinoma in situ, and most of them have good treatment effects. Non-special types of invasive cancer mainly include invasive ductal carcinoma and invasive lobular carcinoma. This type has low differentiation and poor prognosis. Among them, invasive ductal carcinoma accounts for 80% of breast cancer and is the most common type of breast cancer. After the diagnosis of breast cancer is confirmed. Comprehensive treatment needs to be carried out according to the specific stage and molecular classification of the tumor, including surgery, chemotherapy, radiotherapy, endocrine therapy and even targeted therapy.

How to perform surgery after chemotherapy for breast cancer?

Breast cancer requires new chemotherapy and surgery, mainly because the condition is different. If breast cancer is found in the early stage, surgery can be done first, followed by chemotherapy. If breast cancer has reached the middle or late stage, the opportunity for surgery may have been lost. Chemotherapy can first control breast cancer to a certain extent, and then remove the breast cancer, which can not only increase the success rate of surgery, but also effectively prolong life.
