Overview

Hepatocellular carcinoma is the most common type of liver cancer. It originates in liver cells and is a type of malignant tumor. The liver is very important for detoxification, metabolism, and digestion. Liver cancer can either start in the liver itself or spread from another organ. Chronic liver disease is often linked to primary liver cancer. It can be hard to find out about early stages because they don't always show many signs. Newer imaging and treatment methods have improved management, especially when the disease is found early.

Symptoms
Some signs of liver cancer are constant pain in the stomach, swelling in the upper right abdomen, weight loss that can't be explained, tiredness, and loss of appetite. Jaundice, which causes the skin and eyes to turn yellow, can occur. Some people feel sick, throw up, or feel full after eating small amounts. Fluid may accumulate in the abdomen as the disease progresses.

Causes
The most important risk factor is chronic liver disease. Cirrhosis, fatty liver disease, and long-term hepatitis B or C infection raise the risk. Obesity, diabetes, and drinking too much alcohol, as well as being around certain toxins, are other things that can make it worse. A family history and genetic predisposition may increase susceptibility in certain individuals.

Diagnosis
To detect abnormal growths, doctors perform blood tests, such as tumor marker tests, and imaging tests, such as ultrasound, CT scan, or MRI. Sometimes a biopsy is performed to confirm the diagnosis. More tests determine the stage of the disease and how far it has spread.

Treatment
The stage of the disease and the liver's function will determine the treatment. There are several options, including surgery to remove the tumor, liver transplantation, local ablative therapies, targeted therapy, immunotherapy, and chemotherapy. Surgery or transplantation may work well to treat cancers that are still in their early stages. Managing underlying liver disease is important for better outcomes.

The outlook depends on how far the disease has progressed and how well the liver is functioning. Finding it early increases the chances of survival. Vaccinating against hepatitis, limiting alcohol, and controlling liver disease are all examples of preventive measures that lower risk and promote long-term health.
