Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] 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 because ...
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research.
HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...
Inside the microenvironment of the original tumor, the immune system is suppressed so is less able to kill cancer cells. However, once these lone cancer cells migrate, the immune system can target ...
Main histopathology features of squamous-cell carcinoma. Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive ...
There are two types of circulating tumor cell cluster, one that consists of cancer cells only is termed homotypic. A CTC cluster that also incorporates other cells including white blood cells, fibroblasts, endothelial cells (i.e., cells that line the interior surface of blood vessels), and platelets, is termed heterotypic. [24]
Some types of cancer are named for the size and shape of the cells under a microscope, such as giant cell carcinoma, spindle cell carcinoma and small-cell carcinoma.

Binucleated cells may be mistaken for two cells in close proximity when viewing only nuclei. The binucleated cell above is an oral squamous cell carcinoma, cell line UPCI-SCC-103.
