The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells , with the potential to invade or spread to other parts of the body. [ 1 ]
Cancer is fundamentally a disease of tissue growth regulation. For a normal cell to transform into a cancer cell, the genes that regulate cell growth and differentiation must be altered. [ 96] The affected genes are divided into two broad categories. Oncogenes are genes that promote cell growth and reproduction.
Deaths. 353,500 (2015) [ 8] Leukemia ( also spelled leukaemia; pronounced / luːˈkiːmiːə / [ 1] loo-KEE-mee-ə) is a group of blood cancers that usually begin in the bone marrow and produce high numbers of abnormal blood cells. [ 9] These blood cells are not fully developed and are called blasts or leukemia cells. [ 2]
Cancer cell. Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died ...
The International Classification of Diseases for Oncology ( ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries . It is currently in its third revision (ICD-O-3).
Frequency. 904,000 (2015) [ 6] Deaths. 60,700 (2015) [ 7] Chronic lymphocytic leukemia ( CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell ). [ 2][ 8] Early on, there are typically no symptoms. [ 2] Later, non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss ...
Carcinoma is a malignancy that develops from epithelial cells. [ 1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [ 2] or ectodermal germ layer during embryogenesis. [ 3]
Tumors of the hematopoietic and lymphoid tissues ( American English) or tumours of the haematopoietic and lymphoid tissues ( British English) are tumors that affect the blood, bone marrow, lymph, and lymphatic system. [ 1][ 2] Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease ...
