​Transarterial Chemoembolization (TACE) is a minimally invasive procedure in which chemotherapy and embolic agents are directly delivered to a cancerous tumour via its blood supply. It is most often used to treat primary liver cancer, and sometimes in other types of cancer that have spread to the liver. The embolic agents are used to cut off the blood supply to the tumour without affecting the rest of the liver. Compared to receiving conventional chemotherapy, TACE allows for the maximum amount of chemotherapy agent to reach the tumour, while limiting the amount released into the bloodstream.
