The cancer thrombus visible in the vasculature is one of the high-risk factors, which means that the cancer thrombus can be seen in the pathological specimens of breast cancer and there is a possibility of metastasis, and the specific size of the tumor and the presence of lymph node metastasis in the axilla should be taken into account to stage the breast cancer. If it is stage I or II, the treatment effect is very good and the 5-year survival rate can reach 90% or even more. If it is stage III, the 5-year survival rate can also reach 70-80%. If the patient is in stage IV, which is the advanced stage, the survival rate may be lower, probably around 50-60%. After surgery, patients should come to the hospital regularly for physical examination and review, and if tumor metastasis or recurrence is found, the treatment plan should be changed in time.
