Liver is the largest internal organ of the human body. The hepatoma is the primary liver cancer type of liver. The liver is the vital organ that performs many several functions like processing and storage of nutrients absorbed from the intestine and also the production of the clotting factors that helps in clotting of blood in case of injury or cut along with the blood platelets. Hemangioma is one of the common types of tumors of liver. It starts in the blood vessels, whereas Hepatic adenomas start in liver cells. Women are at higher risk of such tumor if they are on birth controlling pills. Discontinuing them may help to reduce the tumor size. Hepatic tumor begins in many sites in the liver and is not confined as a single large tumor. It is in different numbers where it starts as a spot inside the liver.

Hepatic tumor or liver cancer can be on or inside the liver. There are many types of cancer but the primary type is the malignant. Hepatocellular carcinoma comes under this category. Growth of these can be benign or malignant. This can be discovered by medical imaging even if it is not done specifically for the diagnosis of liver cancer.

Most of the time the liver is not the origin of the cancer but it get spread to liver from the other body parts. These tumors are then named after the place where they originate in body and furthermore called as metastatic. Liver cancer symptoms of this kind can b the lump in the abdomen or yellowing of skin but you may not seen them until the cancer is advanced to other stage.

Some researchers have a notion that the cancer every cancer starts with the damage of the DNA. DNA is basically a body library which has all the things related to the chemical processes going on in our body. Even the rate of cellular growth is included. The damage in the DNA causes the cells to grow abnormally and they grow out of control forming the masses which are eventually termed as tumors.  Hepatitis B virus (HBV) infection is the primary cause of the liver cancer in humans. It relates to the frequency of the virus. Studies on animals also prove the fact. Injecting the virus in mice causes him to develop the liver cancer, although the mice seldom develop liver cancer.
