Small liver cancer can be treated with both intervention and ablation, which requires doctors to personalize the treatment according to the actual situation and choose the most suitable surgical method for the patient, and both of them may achieve the effect of clinical cure. 1. Small liver cancer suitable for intervention: intervention can stop the blood supply to small liver cancer by embolizing the blood supplying artery of small liver cancer, so that the artery will stop supplying blood to small liver cancer and cause it to be necrotic, so as to achieve the therapeutic purpose, but patients with poor liver function and distant metastasis need to consider it carefully. 2. Small liver cancer applicable to ablation: for small liver cancer without clear blood supply artery, it is not suitable to use intervention to carry out treatment at this time, and this kind of situation is more suitable for radiofrequency ablation, but radiofrequency ablation is prone to damage the surrounding tissues and gastrointestinal tract related damages. However, radiofrequency ablation may easily damage the surrounding tissues and cause gastrointestinal damage. Intervention and ablation are both effective in the treatment of small liver cancer, and the most suitable treatment plan should be chosen under the guidance of doctors.
