It is common sense that a blood test can detect liver cancer, and the blood test is used to determine whether liver cancer is present by looking for elevated tumor markers in the blood, but elevated tumor markers do not necessarily mean that liver cancer is present.
Liver cancer can be screened by the following techniques: 1. Ultrasound: This is a non-invasive test that does not affect the human body, and ultrasound is relatively simple and inexpensive to perform. It is mainly used to further confirm the diagnosis of liver cancer, and at the same time, it can clarify the staging of liver cancer and play a certain role in the judgment and auxiliary function of liver cancer. 3.PET: The whole body can be scanned by this technology, so that the overall condition and metastasis of liver cancer can be effectively understood, which has a more comprehensive effect on the judgment of liver cancer staging and prognosis. It has a more comprehensive effect in determining the stage and prognosis of liver cancer, but is relatively expensive and is usually not recommended as a first choice test.
