What are the characteristics of small liver cancer? How to diagnose whether it is small liver cancer?

Many people may not know much about small liver cancer. In fact, compared with large liver cancer, small liver cancer, like ordinary liver cancer, does not have obvious symptoms in the early stage, so it is difficult to detect in the early stage. However, the treatment of cancer is more effective when it is discovered early, so the diagnosis of small liver cancer plays an important role. What are the common diagnostic methods for small liver cancer? How does small liver cancer form?

Small liver cancers have no symptoms at first. The tumor nodules are spherical, with clear edges and no bleeding or necrosis. The diagnosis criteria for small liver cancers in my country are: the diameter of a single cancer nodule must be less than 3 cm, the number must not exceed 2, and the total diameter must not exceed 3 cm.

1. People with a high risk of small liver cancer, such as those with chronic hepatitis, a history of cirrhosis, positive HBV or HCV serological indicators, men over 40 years old, especially men who like to drink, must undergo regular check-ups, which is one of the main ways to detect early small liver cancer.

2. AFp (alpha-fetoprotein) and B-ultrasound are one of the most common methods for diagnosing small liver cancer because they are easy to operate, the results are relatively accurate, and the price is cheap.

3. For those with low-concentration positive AFp, AFp heterogeneity detection can be used as an auxiliary measure, and for those with negative AFp, other liver cancer markers can be tested, which is beneficial for the qualitative diagnosis of early liver cancer.

4. The progress of imaging technologies such as ultrasound, CT and magnetic resonance imaging has made it no longer difficult to diagnose small liver cancers less than 1 cm. New contrast agents have further improved the sensitivity of ultrasound and MRI, and ultrasound contrast imaging helps to evaluate the vascular distribution and blood supply of liver cancer. Tissue-specific MRI enhancers (such as superparamagnetic iron oxide) can also further improve the detection of small liver cancers. In addition, the development of three-dimensional imaging technology has also provided a new means for diagnosing small liver cancers.

5. Fine needle aspiration cytology examination under ultrasound guidance is also a good diagnostic method when necessary.

Most cancer patients go to the hospital for examination only when they are extremely unwell, which shows the importance of examination in detecting cancer. If you are unfortunately diagnosed with small liver cancer during the examination, you should receive timely treatment. At this time, most patients are already in the middle and late stages and their physical condition is not very good, so they may not be able to withstand the treatment of Western medicine. On the contrary, Chinese medicine can improve the patient's physical function through drug conditioning and enhance the patient's ability to fight the disease.
