Types of Liver Cancer
There is more than one type of primary liver cancer, and every type has a different etiology and risk factor. However, people often confuse primary liver cancer with secondary or metastatic liver cancer. Primary cancer of the liver starts in the liver. On the other hand, secondary cancer in the liver is cancer that has spread from other locations to the liver. The primary sites of secondary cancer in the liver could be the pancreas, colon, stomach, breast, or lungs. Benign tumors in the liver exist as well. They can grow and cause serious problems, although they do not invade nearby tissues and organs. Usually, these types of benign tumors are treated with surgery if such is needed.
