Cancer happens over time as cancerous cells multiply and grow and sometimes spread (metastasize) from where they started to other areas of your body. When healthcare providers stage cancer, they focus on cancer tumor size and location. They use that information to place cancer in a specific category, or stage, labeled with numbers and letters. Stag...
Tumor-nodes-metastasis (TNM) is the most commonly used cancer staging system. Here’s information on each element in TNM staging: 1. T stands for primary tumor: This is information about a cancer tumor’s size and location at the time of diagnosis. Small tumors that haven’t spread may be classified as stage I tumors.

Stage I:This stage includes smaller tumors (T1-T2) that haven’t spread to nearby lymph nodes (N) or other areas of your body (M0). 2. Stage II:This stage includes larger tumors that haven’t spread to nearby lymph nodes or other areas of your body. T...
