Survival time for breast cancer pleural metastases is currently uncertain, usually months to years, with a low probability of long-term survival. Everyone is different and survival time depends on the individual’s condition and treatment. Breast cancer is a disease of the epithelial cells of the breast in response to a variety of cancer-causing factors. In the early stage of the disease, there will be symptoms such as breast lumps, nipple overflow, enlarged axillary lymph nodes, etc. In the late stage, metastasis will occur. Metastasis in the pleura is caused by the metastasis of cancer cells, which can easily metastasize with the blood of the whole body and is difficult to treat. Therefore, it is necessary to pay attention to it and go to the hospital for relevant examination and treatment in time, take targeted measures to treat it and effectively control the development of the disease so as to prolong the survival period of the patients.
