In order to check if patients have liver cancer, a liver surgeon may prescribe certain diagnostic tests, such as: 1. Ultrasound An ultrasound generates images that can indicate a possible tumour or mass in the liver. 2. Blood Test A tumour marker blood test will check whether an individual has a higher level of AFP (alpha-fetoprotein), which may be a sign of liver cancer. 3. CT Scan A type of x-ray test that creates detailed images of the abdomen. This can help liver cancer surgeons find out the size, shape, and location of growing tumours in the liver, if any. 4. Biopsy By removing a sample of liver tissue for laboratory testing, a biopsy can help doctors check if a patient has liver cancer.
