The survival rate of breast cancer with cancer embolus is between 50% and 90%, which should be analyzed according to the stage. Breast cancer with embolus is a high-risk factor, which mostly indicates that the patient has the possibility of metastasis, but the specific survival rate still needs to be determined in combination with the stage and tumor size. Generally speaking, if the patient is in Stage I or Stage II, the treatment effect is relatively outstanding, and the five-year survival rate can reach 90% or above; for Stage III breast cancer patients, the five-year survival rate will be reduced, and it is mostly kept between 70-80%; for Stage IV, that is, the late-stage patients, the treatment is much more difficult, and the five-year survival rate is around 27%, or even may be even lower. Breast cancer with cancer embolism must take timely and targeted treatment to reduce the chance of metastasis through surgery, radiotherapy and so on.
