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 because of ...
Papanicolaou was studying cancer cells, and needed illustrations of cancer cells to train other doctors to identify diseased cells for cancer screening. Murayama used a camera lucida to project an image of the cells under the microscope onto paper. It was essential for Murayama to identify key examples in the groups of cells that could best ...
The cancer stem cell hypothesis proposes that the different kinds of cells in a heterogeneous tumor arise from a single cell, termed Cancer Stem Cell. Cancer stem cells may arise from transformation of adult stem cells or differentiated cells within a body. These cells persist as a subcomponent of the tumor and retain key stem cell properties.

An illustration depicting primary tumor (in the form of tumor microenvironment) and the circulating tumor cells. A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1]
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. An immortalized cell line reproduces indefinitely under specific ...
A drawing of ductal carcinoma in situ in the anatomical context of the whole breast A drawing of a breast duct containing ductal carcinoma in situ. Most of the women who develop DCIS do not experience any symptoms. The majority of cases (80-85%) are detected through screening mammography. The first signs and symptoms may appear if the cancer ...
Diagram showing the cells where AML develops. The malignant cell in AML is the myeloblast. In normal development of blood cells (hematopoiesis), the myeloblast is an immature precursor of myeloid white blood cells; a normal myeloblast will mature into a white blood cell such as an eosinophil, basophil, neutrophil or monocyte.
