The five-year survival rate of microwave ablation for liver cancer is about 30%-70%, of which the five-year survival rate after ablation for a single small liver cancer can be about 60%-70%. However, the specific survival period varies from person to person and cannot be generalized. Generally, liver cancer suitable for microwave ablation is single <5cm, multiple liver tumors ≤3 in total, and the largest diameter <3cm, generally with better prognosis. Tumors smaller than 5cm are called small hepatocellular carcinoma, tumors larger than or equal to 5cm are called large hepatocellular carcinoma, and tumors larger than or equal to 5cm and smaller than or equal to 10cm are called massive hepatocellular carcinoma. The 5-year survival rate after microwave ablation for a single patient with small hepatocellular carcinoma can be up to 70%, while the 5-year survival rate for patients with multiple tumors is significantly lower and may be around 30%. Survival rates after liver cancer ablation cannot be generalized and must be followed up regularly after treatment. It is important to follow the doctor's instructions for regular review to detect recurrent tumors as early as possible. The earlier the treatment, the better the efficacy and the longer the survival time.
