What are the principles and methods of liver cancer screening
summary
Because recently I felt pain in the liver area, and my skin was yellowing, I went to the hospital for a physical examination. The doctor said that the symptoms were a little like liver cancer, so he gave me an ultrasound examination and CT. Next, I'd like to talk about the principles and methods of liver cancer screening?
What are the principles and methods of liver cancer screening
First, ultrasound examination, B-ultrasound examination is economical and convenient, can show the size, shape and location of the tumor, the diagnostic accuracy is about 90%. The detection rate of liver lesions is also relatively high. Generally speaking, it takes about 4-6 months for liver cancer to grow from 1 cm to 3 cm. So if you don't see liver cancer in the first B-ultrasound examination, if you take another photo after 4-6 months, the liver cancer should still be less than 3cm, and the effect of treatment should be good.
Second: alpha fetoprotein examination, when B-ultrasound and / or CT imaging examination is suspected to be early liver cancer, it is generally recommended to do a alpha fetoprotein examination for auxiliary diagnosis. However, for patients with liver cancer, alpha fetoprotein may not be one of the most common markers, but we can not exclude alpha fetoprotein.
Third: CT, with CT examination of liver cancer is a vital means, in the country to do more. However, when the diameter of liver cancer is less than 2 cm or the density is similar to normal liver essence, CT is difficult to show. It is difficult to distinguish primary and secondary liver cancer.
matters needing attention
The size and development of the tumor can be seen accurately by ultrasound examination. Generally, liver cancer can be diagnosed by alpha fetoprotein examination. After the diagnosis, patients must actively cooperate with doctors for treatment as soon as possible, so as to prevent the later deterioration and metastasis of liver cancer to other parts.
