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 ...
HeLa ( / ˈhiːlɑː /) is an immortalized cell line used in scientific research. It is the oldest human cell line and one of the most commonly used. [1] [2] HeLa cells are durable and prolific, allowing for extensive applications in scientific study. [3] [4] The line is derived from cervical cancer cells taken on February 8, 1951, [5] from ...
Average five-year survival 66% (USA) [5] Frequency. 24 million annually (2019) [6] Deaths. 10 million annually (2019) [6] Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] These contrast with benign tumors, which do not spread. [7]
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor.
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.

The hallmarks of cancer were originally six biological capabilities acquired during the multistep development of human tumors and have since been increased to eight capabilities and two enabling capabilities. The idea was coined by Douglas Hanahan and Robert Weinberg in their paper " The Hallmarks of Cancer " published January 2000 in Cell.
A circulating tumor cell ( CTC) is a cell that has shed into the vasculature or lymphatics [1] from a primary tumor and is carried around the body in the blood circulation. CTCs can extravasate and become seeds for the subsequent growth of additional tumors ( metastases) in distant organs, a mechanism that is responsible for the vast majority ...
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.
