For patients with lung metastases from breast cancer, survival varies greatly depending on the treatment plan, sensitivity to treatment, and the individual’s specific physical condition, etc. Survival is generally not too long, and the five-year survival rate is not high. Lung metastasis from breast cancer means that the breast cancer has entered an advanced stage, and the survival time is not certain, and there is no clear data to support it. However, it is not that there is no hope when breast cancer metastasizes to the lungs, and active radiotherapy, chemotherapy, targeted therapy and other treatments can be carried out to prolong the survival period and alleviate the pain. Patients with breast cancer metastasized to the lungs are advised to go to regular hospitals, consult professional doctors, and cooperate with doctors to complete laboratory tests to avoid blind treatment.
