Cancer cell

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 of aging or damage.^[2] Healthy cells stop dividing when there is no longer a need for more daughter cells, but cancer cells continue to produce copies. They are also able to spread from one part of the body to another in a process known as metastasis.^[3]
