Active foci on the liver usually indicate that the tumor lesion is still in an active state, and is prone to progressive enlargement or metastasis if treatment is not continued. When liver cancer patients find active foci on the liver during review after treatment, it usually indicates that the tumor lesions are still in active state. If the tumor shrinks after treatment, the overall therapeutic effect is still good although there is still activity, and the treatment should be adhered to. If after treatment, the tumor does not shrink, but grows rapidly and is still active, this situation usually indicates that the treatment effect is not satisfactory. At this time, it is necessary to make a comprehensive analysis of the patient’s systemic condition, liver function and tumor condition, so as to choose the appropriate treatment. Patients with active foci detected on the liver should inform the attending physician in time, and choose the appropriate treatment plan according to the specific situation, so as to avoid delaying the condition.
