When unhealthy cells grow and spread in the liver than it results in liver cancer. Primary liver cancer begins in the liver. Metastatic liver cancer is the cancer that spreads to the liver through some other organ. Liver cancer includes some common benign tumors such as -
Hepatoblastoma: A rare type of liver cancer is usually seen in children. The early detection of this cancer can offer about 90% of survival rate.
Hepatocellular Carcinoma (HCC): This is considered as the most primary liver cancers that start from hepatocyte cells. They can begin at multiple spots in the liver or can also start as a single tumor. Hepatocellular carcinoma begins in multiple spots in the liver in those people who have liver damage.
Hemangiosarcomas and Angiosarcomas: They are considered as the fast growing liver cancers that start in the blood vessels in the liver. They can only be diagnosed when they are in their advanced stages.
Fibrolamellar HCC: This is considered as rare and can be effectively treated as compared to other types of liver cancer.
Bile Duct Cancers (Cholangiocarcinomas): This type begins in the bile duct that is small tubes carrying bile to the gallbladder.
The skin is thoroughly examined for seeing dry patches, growths or moles. Sometimes a dermoscope is also used for better viewing of the skin. This device emits light and magnifies the skin that helps in viewing structures of the skin. Biopsy is also used for diagnosing skin cancer that is safe and quick to perform. Some other tests may also be required if melanoma is diagnosed. Some of these include -
Stage 1: There is the presence of only one tumor in the liver in this stage.
Stage 2: Here also in the second stage, one tumor is present that has spread to the blood vessels. There could also be more than 1 tumor that is of about 5cm.
Stage 3: In the third stage, only one tumor is present that is bigger than 5cm. It could also be possible that the cancer has moved beyond the liver to lymph nodes, blood vessels or to another organ.
Stage 4: At this last stage, the cancer has spread to other parts of the body that include bones or lungs along with lymph nodes or blood vessels.
Physical examination helps in determining symptoms or lumps that may suspect the presence of liver cancer. Some of the other tests that are performed for diagnosing liver cancer include -
Percutaneous ethanol injection, surgery and chemotherapy are the three methods for treating liver cancer. Some of the surgical treatments include -
Anti-cancer drugs are used in chemotherapy for destroying cancer cells or preventing them from reproducing. Chemoembolization of the hepatic artery is another type of chemotherapy used for treating liver cancer. In this the chemotherapy drugs are combined with another substance in order to block the artery. The aim is to destroy the tumor blood and then applying chemotherapy directly to the tumor.
During this therapy, ethanol is injected into a tumor for destroying the cancer. This therapy is not used frequently.
