What is liver cancer?
Liver cancer happens when normal cells in the liver change into abnormal cells and grow out of control. The liver is a big organ in the upper right side of the belly.
Most people who get liver cancer have long-term liver disease (also called chronic liver disease). Having long-term liver disease increases a person’s chances of getting liver cancer. The most serious form of long-term liver disease is a condition called “cirrhosis,” which scars the liver.
