Breast cancer can be categorized into invasive breast cancer, non-invasive breast cancer and so on. 1. Invasive breast cancer: invasive breast cancer usually means that the cancer cells break through the basement membrane and present burrs, unclear border and infiltration to the periphery, etc. Invasive breast cancer usually has a higher degree of malignancy, and the time for metastasis and spread of cancer cells is shorter. 2. Non-invasive breast cancer, the cancer cells in non-invasive breast cancer usually do not break through the basement membrane, and generally will not metastasize or shed, so the time for cancer cells to metastasize and spread will be relatively long, and the degree of malignancy will also be relatively low. At the same time, breast cancer has molecular immunopathological classification, which is based on estrogen receptor (ER), progesterone receptor (PR), HER-2 receptor and Ki67 index, including Luminal A, Luminal B and triple-negative breast cancer. It is recommended that patients should first go to the hospital for relevant examinations and do the appropriate treatment according to their own conditions.
