Cancer embolism is formed by cancer cells entering blood vessels or lymphatic vessels, which may disappear after treatment, but will continue to develop and grow into malignant tumor if not treated. Therefore, when symptoms like cancer embolism appear, systemic treatment must be carried out, mainly through chemotherapy, radiotherapy, immunotherapy, targeted drug therapy, biological therapy, liver cell transplantation, microwave ablation therapy, interventional therapy, combined Chinese and Western medicine therapy, etc. By combining these treatments, it is possible for the cancer clots to become smaller or disappear through anti-tumor therapy, thus controlling the disease and prolonging the life span of patients.
