Cancer is a disease or disorder of the body as a result of body cells that grow and develop abnormally, beyond the acceptable limit and very wild. Condition of cancer occurs when normal cells change with rapid growth, so can not be controlled by the body and are not formed. Cancer can occur in any part of the body. When cancer occurs at the surface of the body, will be easily detected and treated. But when going on inside the body, the cancer will be difficult to know and sometimes have no symptoms. If symptoms develop, usually so difficult to treat advanced stage.
Some types of cancer that has been known until now is:
Carcinoma is a type of cancer arising from cells lining the surface of the body or surface of the body channels, such as epithelial tissue such as skin cells, testis, ovary, glands muskus, melanin cells, breast, neck Ahim, colon, tektum, stomach, pancreas and esophagus.
Lymphoma is a cancer arising from tissues that form blood, lymph tissue for example, lacteal, lymph, various lymph nodes, thymus and bone marrow. Specific lymphomas include Hodgkin's disease (lymph nodes and lymph cancer).
Leukemia does not form a tumor mass, but meet the blood vessels and interfere with normal blood cell function.
Sarcoma is a cancer support network that is under the surface of the body such as connective tissue, including cells found in muscle and bone.
Glioma is a cancer of nervous system, such as glia cells (supporting tissue) in the central nervous system.
Carcinoma in situ
This is a term used to describe abnormal epithelial cells that are still limited in certain areas so it is still considered prainvasif lesion (abnormality / injury that has not spread).
