Can liver cancer be diagnosed by color Doppler ultrasound in early stage?

Liver cancer is a malignant tumor, early stage usually has no obvious symptoms, so it is difficult to find through self-examination. When the tumor increases to a certain extent, there may be abdominal mass, abdominal pain, abdominal distension and other symptoms, but these symptoms are not specific, may also be caused by other diseases. Color Doppler ultrasound is a commonly used imaging method, can observe the shape, size, structure and other conditions of the liver, for the diagnosis of liver cancer has certain help. However, color Doppler ultrasound is not sensitive to the early diagnosis of liver cancer, and it is easy to miss or misdiagnose. If liver cancer is suspected, other examinations such as alpha-fetoprotein (AFP) detection, CT, magnetic resonance imaging (MRI), etc. are needed. AFP is a specific marker of liver cancer and is of great significance for the diagnosis of liver cancer. If AFP is elevated, combined with other test results, it is helpful to diagnose liver cancer. In addition, liver biopsy is the gold standard for diagnosing liver cancer. It can directly observe pathological changes in liver tissue and confirm the diagnosis. However, liver biopsy is an invasive test and needs to be performed under the guidance of a doctor. For high-risk groups of liver cancer, such as hepatitis B, hepatitis C patients, long-term alcoholics, liver cirrhosis patients, etc., liver cancer screening should be carried out regularly in order to detect liver cancer early and improve the cure rate. In short, liver cancer may not be seen early by color Doppler ultrasound, but it needs to be combined with other examinations for comprehensive judgment. If liver cancer is suspected, it should be treated promptly for further examination and diagnosis.
