AI Summary TACE is a minimally invasive, image-guided procedure that delivers chemotherapy directly into the artery feeding a liver tumor while blocking its blood flow.
Medically reviewed.
Transarterial chemoembolization (TACE) is a minimally invasive, image-guided procedure that treats liver cancer by delivering chemotherapy directly into the artery that feeds a tumor while blocking its blood flow. This dual action traps the chemotherapy inside the tumor and cuts off its oxygen and nutrient supply. TACE is typically used for people with liver cancer who are not candidates for surgery or transplant. Treatment decisions should always be individualized and guided by a healthcare professional.
This page covers TACE's role in liver cancer treatment — how it works, who may be eligible, benefits, side effects, and monitoring. You can also connect with a liver specialist near you for personalized guidance on whether TACE fits your care plan.

ABOUT TACE TREATMENT
Transarterial chemoembolization, or TACE, is a minimally invasive, image-guided procedure used to treat liver cancer. It works by delivering chemotherapy directly into the artery that supplies blood to a tumor, then blocking that blood flow. This dual action traps the chemotherapy inside the tumor and cuts off its oxygen and nutrient supply.
Unlike systemic chemotherapy, which travels through the bloodstream to the whole body, TACE concentrates treatment at the tumor site. This increases the local drug concentration reaching the cancer while reducing the amount of chemotherapy that reaches the rest of the body.
TACE is a locoregional therapy, grouped alongside treatments such as histotripsy. It is typically performed by an interventional radiologist and is often repeated in sessions over time, depending on how the tumor responds and how well the liver is functioning.
WHO TACE MAY BE SUITABLE FOR
Your healthcare provider may recommend TACE if you have unresectable hepatocellular carcinoma — meaning the tumor cannot be safely removed with surgery. TACE is generally considered when cancer is confined primarily to the liver, when you are not a candidate for surgery or liver transplantation, and when you need localized treatment to control tumor growth.
Because every patient's tumor and liver condition is different, there is no one-size-fits-all answer to who should have TACE. Your healthcare provider determines whether this treatment is appropriate after reviewing your imaging, laboratory testing, and overall liver function.
ELIGIBILITY OVERVIEW
TACE may be considered for adults with the following conditions, needs, or treatment goals:
Before recommending TACE, healthcare providers evaluate several factors to determine whether it is an appropriate option, including:
HOW TACE CAN HELP YOUR LIVER
TACE works by combining two actions in one procedure: chemotherapy delivery and blood vessel blockage. A catheter delivers chemotherapy directly into the artery that feeds the tumor, so the drug reaches the cancer at a much higher concentration than systemic chemotherapy would allow.
After the chemotherapy is delivered, embolic particles are injected to block the blood vessels feeding the tumor. This cuts off the tumor's oxygen and nutrient supply while also helping to retain the chemotherapy within the treated area for longer.
Together, these effects increase local drug concentration, reduce how much chemotherapy reaches the rest of the body, and help slow tumor growth. TACE is typically performed by trained specialists under imaging guidance, often in sessions spaced weeks or months apart, depending on tumor response and liver function.
LIVER BENEFITS
During TACE, a catheter carries chemotherapy straight into the artery that feeds the tumor. The drug goes where the cancer is, instead of traveling through the whole bloodstream first. This is why TACE is called a targeted, locoregional treatment.
After the chemotherapy is delivered, embolic particles are placed in the same artery. They block the blood vessels that feed the tumor and cut off its oxygen and nutrient supply. The blockage also helps hold the chemotherapy inside the treatment area.
Because the drug is delivered into the tumor's own blood supply and then trapped there, the concentration of chemotherapy at the cancer rises. The combined effect of chemotherapy and blocked blood flow helps slow tumor growth.
Since the chemotherapy stays mostly at the tumor site, less of it reaches the rest of the body. Your care team still monitors your overall health and liver function closely during and after each session.
TACE works by delivering chemotherapy directly to a liver tumor while blocking its blood supply, helping slow tumor growth. It should only be performed and monitored under the guidance of a qualified healthcare team.
TREATMENT PROCESS
Imaging studies and laboratory testing are completed before treatment to assess the tumor and liver function.
A small catheter is inserted through an artery, typically in the groin or wrist, and guided to the blood vessels supplying the liver tumor.
Chemotherapy is delivered directly into the tumor-feeding artery, followed by embolic particles that block blood flow to the tumor and help retain the chemotherapy within the treatment area.
Most patients are observed for several hours or overnight after the procedure. Recovery time varies, and some patients may experience temporary symptoms related to post-embolization syndrome.
TACE is performed in sessions, often repeated every few weeks or months depending on tumor response and liver function.
Follow-up imaging evaluates how the tumor has responded to treatment.
BENEFITS AND SAFETY
TACE may support people with unresectable hepatocellular carcinoma by delivering chemotherapy directly to the tumor while blocking its blood supply, helping slow tumor growth. Because treatment is concentrated at the tumor site, TACE is minimally invasive and does not require major surgery, and it reduces the amount of chemotherapy that reaches the rest of the body compared with systemic chemotherapy. The extent of these benefits varies from person to person, depending on tumor size, location, and overall liver function.
TACE is not a stand-alone treatment — it is typically repeated in sessions and paired with follow-up imaging to track tumor response, alongside hydration, avoiding alcohol, and liver-friendly nutrition.
As with any procedure, TACE may cause side effects. The most common is post-embolization syndrome, which can include pain, fever, nausea, and fatigue. Other effects include abdominal discomfort, loss of appetite, and temporary liver enzyme elevation. Your healthcare provider will monitor your treatment response and liver function through follow-up imaging and clinical assessments.
BENEFITS
TACE delivers treatment directly to liver tumors. The chemotherapy is placed in the artery that supplies the cancer, so treatment is concentrated where it is needed most.
By trapping chemotherapy in the tumor and cutting off its blood supply, TACE helps slow cancer progression. Sessions are often repeated every few weeks or months, and follow-up imaging shows how the tumor is responding.
TACE does not require major surgery. The catheter enters through a small access point, usually in the groin or wrist, which makes it an option for people who are not candidates for surgery or transplantation.
Because the chemotherapy is concentrated at the tumor, less of it reaches the rest of the body than with systemic chemotherapy. Benefits vary from person to person, so your healthcare provider can explain what to expect in your situation.
These effects are often temporary and tend to improve within days. Your healthcare provider will discuss the potential benefits and risks before treatment and provide ongoing support, including follow-up imaging, to monitor treatment response.
SUPPORTING YOUR RESULTS
After TACE, patients are advised to maintain hydration, avoid alcohol, follow liver-friendly nutrition, and adhere closely to oncology follow-up schedules.
These habits can support recovery and help your healthcare team track how your liver and tumor respond between treatment sessions.

COMMON QUESTIONS
No, TACE is not a cure for liver cancer. It is a locoregional treatment that delivers chemotherapy directly to a tumor while blocking its blood supply, which helps slow tumor growth. Whether it offers a lasting benefit depends on your tumor's response, your disease stage, and whether additional therapies are needed. Talk with your healthcare provider about realistic goals for your treatment plan.
