The liver is made up of different types of cells. The cells of the liver grow and divide in a controlled way to produce new cells needed to replace the old and dead cells to keep the organ healthy. Damage to the DNA (the material that provides instructions for every chemical process in all the cells and tissues of the body) causes loss of division of the cells in a controlled way.

Research scientists are currently trying to search for the exact cause of liver cancer.
