Tumor-Node-Metastasis (TNM) Classification

The Tumor-Node-Metastasis (TNM) classification is a system used by doctors to describe the extent of cancer in a patient's body. It has three main parts: 1. **Tumor (T)** - assesses the size and local extent of the primary tumor. 2. **Node (N)** - evaluates whether cancer has spread to nearby lymph nodes. 3. **Metastasis (M)** - indicates if the cancer has spread to distant parts of the body. By categorizing cancer in this way, doctors can better plan treatment and predict outcomes for patients.
