There are differences between benign and malignant liver tumors in terms of growth rate, growth mode, metastasis and recurrence. 1. Growth rate: benign liver tumors usually grow slowly, while malignant tumors usually grow rapidly, which can compress the surrounding organs and bring discomfort to patients. 2. Growth mode: benign liver tumors have smooth surface, clear boundary, mostly have formed envelope, and do not adhere to the surrounding tissues. Malignant tumors show infiltrative and destructive growth, with rough and uneven surface, unclear boundary and adhesion with surrounding tissues. 3. Metastasis: benign liver tumor will not metastasize. Malignant tumors can be transferred to other parts of the body through lymphatic channels and blood channels. 4. Recurrence: benign liver tumors can be cured after surgery and the recurrence rate is low, but malignant tumors can metastasize and spread faster and the probability of recurrence is relatively high. It is suggested that patients with liver tumor should go to the hospital in time and differentiate themselves under the guidance of professional doctors, so as to avoid the adverse consequences caused by self-diagnosis errors.
