Liver stones are commonly formed whenever an excess of cholesterol exists in the body. When excess dietary cholesterol is present, the remainder often crystallizes into small, pebble-shaped masses. Recently, researchers at the University of Bonn in Germany discovered that heredity may ... be a contributor to the condition. The scientists believe they have isolated a gene within the body that greatly increases a person’s chances of forming liver and/orgallstones.2

The most common types of benign liver tumors are hemangiomas (which are a cluster of abnormal blood vessels forming a swelling), and adenomas (which are clumps or knots of liver tissue). The most common malignant liver cancers are hepatocellular carcinoma (80% of cases) which arises from the liver cells themselves, and is ... known as ahepatoma (a poor name for liver cancer, since it sounds benign). Cholangiocarcinoma (15% of cases) arises from bile ducts in the liver as they proceed down toward the gallbladder. A Klatskin tumor is a cholangiocarcinoma located at where the gall bladder meets the liver. Rare types of liver cancer include the angiosarcoma (which arises from the blood vessels in the liver), lymphomas (from the immune cells in the liver) and carcinoids (from hormone making liver cells). The liver is a very common place for cancers originating in other body organs to spread to; since it offers a soft, spongy blood-rich surface for metastatic "seeds" to grow.

Hepatitis B and C. Worldwide, chronic infection with the hepatitis B virus (HBV) or hepatitis C virus (HCV) is the most common cause of liver cancer. In the United States, hepatitis C infection is responsible for half the new cases of hepatocellular carcinoma (HCC), the most common type of primary liver cancer. Hepatitis C is transmitted primarily through transfusions with blood that hasn't been screened for the virus, through contaminated needles used to inject drugs or, less commonly, through needles used in tattooing or body piercing. In some cases, hepatitis C may be transmitted sexually. Just how it damages DNA isn't well understood. The virus doesn't insert its genetic material into healthy liver cells the way HBV does, but some experts think that the virus may interfere with the action of a gene that prevents cells from reproducing at an accelerated rate.

The cells in the liver are meant to divide to replace those that die of injury or old age. Like all cell division in the body, this process is tightly controlled to proceed in an orderly manner, and controlled by the "genes" within each cell. Liver cancer starts within a single cell. Something changes the control mechanisms within this cell, and it starts dividing in a disorganized, uncontrolled manner. The abnormal cell makes millions of copies of itself, called "clones". They fail to perform the normal functions of liver cells, but are only intent on dividing to make more copies of themselves.

The liver can be affected by primary liver cancer, which arises in the liver, or by cancer which forms in other sites and then spreads to the liver. Most liver cancer is secondary or metastatic, meaning the malignancy originated elsewhere in the body -- usually the colon, lung or breast. Primary liver cancer, which starts in the liver, accounts for about 2% of cancers in the U.S., but up to half of all cancers in some undeveloped countries. This is mainly because of the prevalence of hepatitis, caused by contagious viruses, that predisposes a person to liver cancer. Worldwide, primary liver cancer strikes twice as many men as women and is most likely to affect people over 50.
