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.  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.
