Understanding of Cancer. Talking about cancer would not be separated from the name of the wallet, money and old dates. Naturally, if the cancer is translated as "dry bag". This course will be the opposite if the cancer is discussed according to the original. Cancer is one of the most dangerous diseases caused by growth or division of cells that are not normal tissue, which is expanding rapidly, out of control, and will continue to divide. The uncontrolled growth, causing mutations in vital genes that control cell division. Some mutations can transform normal cells into cancer cells (Brunner et al, 2005).
Cancer is a condition in which the cells have lost the normal mechanisms of control and, thus experiencing abnormal growth, rapid and uncontrolled. Cancer can occur from a variety of tissues in various organs. In line with the growth and breeding, cancer cells form a mass of cancerous tissue that infiltrate nearby tissues (invasive) and can spread (metastasize) throughout the body.

Determination Stage Cancer
To determine the stage, generally a cancer is classified first according to the TNM system (Tumor, Node, Metastasis) :
Tumor : large or extensive tumor origin
Tis = tumor has not spread to the surrounding tissues;
T1 = tumor size of 2 cm or less in diameter
T2 = tumor size between 2-5cm
T3 = tumor size diameter> 5cm
T4 = What size but has spread, can form ulcers
Node : the spread of cancer to lymph nodes
N0 = not spread to the lymph nodes;
N1-3 = degree of spread
Metastases : presence / absence of spread to distant organs
M0 = no / not yet rated
M1 = there metatasis far

M1 = there metatasis far
TNM classification aim is to planning treatment, determining prognosis (probability estimates improve / recover), evaluation of treatment outcomes, and also for the exchange of information among cancer treatment centers (for reference). So there is cancer stage I, II, III and IV, stage I and II is also called early-stage, while stage III-IV also called locally advanced or stage IV also called locally advanced or metastatic.
