Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [ 1 ] was an African-American woman [ 4 ] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [ A ] and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific ...
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 ...
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. [26]
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]
On the other hand, those with the healthiest lifestyles had a 1.6% chance of colorectal cancer with regular aspirin use and a 1.5% chance without it, leading to a 0.1% lower absolute risk of ...
For example, the most common cancer of the liver parenchyma ("hepato-" = liver), arising from malignant epithelial cells ("carcinoma"), would be called a hepatocarcinoma, while a malignancy arising from primitive liver precursor cells is called a hepatoblastoma. Similarly, a cancer arising from malignant fat cells would be termed a liposarcoma.
