Cancer
Cancer is a disease characterized by a set of cells proliferate abnormally, invade and destroy surrounding tissue and can spread far into the tissue / organs through a process called metastasis. The properties are known as cancer and malignansi that distinguish this cancer from benign tumors (benign tumors), in which benign tumors grow localized, non-invasive, and do not metastasize. Cancer can be of any age, and the risk of getting cancer will increase with increasing age.
Most of cancer due to genetic abnormalities of the material-forming cells. These abnormalities can occur due to the effects of carcinogenic substances (substances that trigger potentially cancer) ATL: tobacco smoke, chemicals, ionizing radiation, and infection of several viruses and bacteria, partly derived from ancestors that caused an error in the process of DNA replication. In summary it can be said that cancer cells derived from cells of tissue / organs of the body’s own previously developed into normal and abnormal.
