Do symptoms of liver cancer appear in the early stages?

In many cases, symptoms of liver cancer may not appear until the disease is in an advanced stage, making early detection a challenge. However, potential symptoms, when they do appear, can include a lump or pain in the right side of the abdomen, and yellowing of the skin and eyes (jaundice) [1].

It is important to understand that these symptoms may be caused by conditions other than liver cancer, but their appearance warrants consulting a doctor to evaluate the condition and determine the cause [2].

Why might symptoms not appear early?

The liver is a large organ with a high capacity for compensation, meaning it can continue to perform its functions even if a portion of it is affected by cancer. This explains why symptoms do not appear in the early stages, as signs only manifest when the tumor becomes large enough to noticeably affect liver function or press on adjacent organs [1].

Potential symptoms of liver cancer

When symptoms do appear, they may include a range of signs that require attention. These symptoms include:

• A lump or pain in the upper right side of the abdomen [1].
• Yellowing of the skin or eyes (jaundice) [1].
• Abdominal swelling [2].
• Unexplained weight loss [2].
• Loss of appetite [2].
• Nausea and vomiting [2].

These symptoms, although they may point to liver cancer, can also be indicative of other health conditions. Therefore, an accurate diagnosis requires specialized medical examination [2].

The importance of early detection and screening

Because symptoms may not appear early, liver cancer detection often relies on periodic screenings for people at risk. Key risk factors include hepatitis B or C infection, excessive alcohol consumption, cirrhosis, hemochromatosis, obesity, and diabetes [1]. You can learn more about risk factors and detection methods in the article Liver Cancer: Risk Factors, Early Detection, and Treatment (Arabic).

A combination of tests is used to diagnose liver cancer, including tests that examine the liver and blood [1]. These tests may include:

• Blood tests, such as liver function tests and the alpha-fetoprotein (AFP) tumor marker [2].
• Imaging tests such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) [2].
• A liver biopsy, where a sample of liver tissue is taken for examination under a microscope [1].

When should you see a doctor?

If you notice any of the symptoms mentioned above, especially if you have known risk factors for liver cancer, it is essential to consult a doctor immediately. Early diagnosis, even if difficult, can significantly impact treatment options and outcomes [1].
