  3. 3.  In the field of oncology, cancer staging helps patients and physicians to classify the severity of a cancer diagnosis.  In addition to helping a physician develop an appropriate course of treatment, it also facilitates prognosis and identifies patients for suitable clinical trials.
  4. 4.  Staging systems typically depend on a number of common elements, including the spread of cancer to the lymph nodes, location of the primary tumor, tumor size, and the number of tumors.  The TNM staging system, one of the most commonly used by physicians today, classifies cancer based on tumor extent, spread to lymph nodes, and the presence of metastasis.  Based on the TNM evaluation, a physician can then place a patient’s cancer diagnosis into one of five stages, which range from Stage 0 to Stage IV.  Stage 0 cancer represents an early cancer that has not spread to other tissues, while stage IV cancer has typically spread to another organ in the body.
