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 ...
Cancers are often described by the body part that they originated in. However, some body parts contain multiple types of tissue, so for greater precision, cancers are additionally classified by the type of cell that the tumor cells originated from. These types include: Carcinoma: Cancers derived from epithelial cells. This group includes many ...
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.
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]
Multiple myeloma ( MM ), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. [ 6] Often, no symptoms are noticed initially. [ 10] As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. [ 10]
(Reuters) -The U.S. health regulator on Tuesday approved Johnson & Johnson's chemotherapy-free combination treatment for a type of non-small cell lung cancer, giving patients access to a therapy ...
Melanoma is the most dangerous type of skin cancer; it develops from the melanin -producing cells known as melanocytes. [ 1 ] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye ( uveal melanoma ). [ 1 ][ 2 ] In women, melanomas most commonly occur on the legs; while in men, on the back. [ 2 ]
When the researchers turned on a cancer-causing gene in the mice during refeeding, the cells were much more likely to develop into precancerous polyps than if the gene was turned on during fasting.
