Computed tomography (CT) scan

An imaging test that takes detailed pictures of the inside of the body using X-rays and a computer

Hepatitis B and hepatitis C

Viral infections that can cause inflammation and damage in the liver. Over time, they may lead to cirrhosis or liver cancer if not treated

Hepatologist

A doctor who specializes in diseases of the liver, gallbladder, bile ducts, and pancreas

Immunotherapy

Liver cancer

Cancer that starts in the liver. uHCC is a type of liver cancer called unresectable hepatocellular carcinoma

Medical oncologist

A doctor who specializes in treating cancer with medicines like chemotherapy, targeted therapy, or immunotherapy

Metabolic conditions

Health problems that affect how the body uses energy, such as Type 2 diabetes and metabolic dysfunction-associated steatohepatitis (MASH)

Metabolic dysfunction-associated steatotic liver disease (MASLD)

A condition where fat builds up in the liver that isn't due to drinking alcohol. Formerly known as non-alcoholic fatty liver disease (NAFLD)

Metabolic dysfunction-associated steatohepatitis (MASH)

The more severe form of MASLD, or fatty liver disease, where fat builds up in the liver, causing inflammation and scarring. Formerly known as non-alcoholic steatohepatitis (NASH)

Multidisciplinary team (MDT)

A group of healthcare professionals from different specialties who work together to plan and manage a patient’s care

Oncology nurse

A nurse who cares for people with cancer, helps give treatments, manages side effects, and provides support and education

Type 2 diabetes (T2D)

A condition where the body doesn’t use insulin properly, leading to high blood sugar levels

Ultrasound

An imaging test that uses sound waves to look at organs inside the body

Unresectable

A tumor that cannot be removed with surgery because of its size, location, or because it has spread to other parts of the body

Unresectable hepatocellular carcinoma (uHCC)

The most common type of primary liver cancer. It starts in the main cells of the liver called hepatocytes. Hepatocellular carcinoma is considered unresectable when the tumor can’t be removed with surgery. This may be due to several reasons. The cancer may be too large to be removed without leaving behind enough of the liver to still work. The cancer cannot be removed in order to keep a safe amount of blood flow coming in and out of the liver. The cancer has spread to other parts of the body
