In clinical practice, the so-called small liver cancer refers to the diameter of the liver cancer after diagnosis. If it is a single tumor, it usually means less than 3 cm. If it is two tumors, the diameter of the general tumor should also be less than 3 cm. This is called small liver cancer. The clinical treatment effect of small liver cancer is quite good, In clinical practice, early surgical treatment or intervention or local microwave, radio frequency and interventional treatment can be performed. Generally, the prognosis is good, and the five-year survival time can even reach more than 50% of the long-term survival. Once the treatment of small liver cancer is confirmed, chemotherapy or other treatments are generally not taken, However, the so-called small liver cancer is just some clinical manifestations and imaging manifestations. Whether it is an early liver cancer still needs some later pathological analysis as a basis.
