Consult your doctor if you have any of the risk factors mentioned above. A blood test for alpha-feto-protein level can signal the presence of liver cancer. Screening for hepatitis B and C is also done.
An ultrasound scan of your liver can help detect the presence of a suspected liver cancer.  Detailed imaging techniques such as CT scan or MRI can also be used to evaluate the presence of liver cancer.
When liver cancer is seen and surgery is not chosen as the mode of treatment, a liver biopsy (a small piece of liver tissue is removed and studied in the laboratory) is performed to determine the suitability of other treatment modalities.
