How to diagnose liver cancer for early detection? Summary of several liver cancer diagnosis methods

CT examination: It is the most common method for diagnosing liver cancer. It has a high resolution and can detect early liver cancer with a diameter of about 1.0 cm. Enhanced scanning can help differentiate it from hemangioma. The diagnostic accuracy rate for liver cancer is as high as 90%. However, it is expensive and cannot be widely used. Selective celiac artery or hepatic artery angiography can sometimes show space-occupying lesions with a diameter of 0.5 to 1 cm for cancers with rich blood vessels. The diagnostic accuracy rate of liver cancer is as high as 90%. It can determine the location, size and distribution of the lesion, especially the localization diagnosis of small liver cancer, which is the best among various examination methods currently available.

X-ray examination: Abdominal fluoroscopy or plain film can show enlarged liver shadows, which is also a common method for diagnosing liver cancer. Cancer in the right lobe of the liver can often be seen with elevated right diaphragm, limited movement or localized bulge. X-ray barium meal examination can show compression of the stomach and transverse colon in the left lobe of the liver or giant liver cancer. Liver puncture and needle aspiration cytology examination has a definite diagnostic significance. Currently, fine needle puncture under the guidance of B-type ultrasound is mostly used, which helps to increase the positive rate, but there are risks such as bleeding, tumor rupture and needle tract metastasis. For patients who still cannot be diagnosed after various examinations but are highly suspected or have been qualitatively diagnosed with liver cancer, laparotomy should be performed if necessary.
