Overview

According to the American Joint Committee on Cancer (AJCC) staging system, there are 4 stages of malignant liver mass, based on 3 factors: tumor size, lymph node invasion, and metastasis. Each stage is assigned a letter and a number that designate T for tumor size, N for node invasion, and M for metastasis.
