Liver cancer, when it starts in the liver, is called the primary cancer of the liver. When cancer spreads in liver, from anywhere in the body, it is called metastatic liver cancer. In United States, rarely found primary liver cancer. Only 2% of malignant tumors in the United States have primary liver cancer. With regard to Africa and Asia, about 10% to 50% of malignant tumors are of primary liver cancer. Hepatocellular carcinoma (HCC) is one of the top 10 most common cancers in the world today. It is more common in men than in women. About 75% cases of primary liver cancer are seen as cases of HCC.
The rate of incidence of cancer of liver metastatic in United States is about 20 times more of primary liver cancer. When the blood passes through the liver filtration, cancer cells of other bodies present in this room of blood in the liver and grow in tumors in the liver. Therefore, spreads the primary cancer of another body (metastasizes) in the liver and is known as metastatic liver cancer. More information on treatment and secondary liver cancer symptoms.
Liver cancer: risk factors
The exact causes of liver cancer are not known. But there are certain elements that may place individuals at increased risk of developing liver cancer. Age, gender, genetics (family history of liver cancer), presence of carcinogens in the environment, use of some oral contraceptives, cirrhosis, alcohol abuse, exposure to the virus of hepatitis are some of the factors commonly observed.

Liver cancer survival rates: affecting factors
Liver cancer survival rates tell us about the percentage of people who survive after the diagnosis of liver cancer, in a specific period of time. Usually, this period is five years. People who are alive five years after the diagnosis of liver cancer are taken into account. “But several factors affect this ‘ survival rate of liver cancer”. Therefore, you can not predict about life expectancy of liver cancer of any patient, with the help of those rates or statistics. The treatment of cancer of the liver and the response of the patient to these treatments vary greatly. The stage of the cancer when it detects the liver functions, the patient’s general health and whether he is following a lifestyle healthy, influence liver cancer survival rates. The levels of Alpha fetoprotein (AFP) also determine the survival rate of liver cancer. When the cancer is diagnosed at an early stage, the survival rate is obviously high. Read more about first signs of liver failure. Regular check-ups and consultation with your doctor, will help to diagnose early stage liver cancer by itself.
Liver cancer survival rates: statistics
The statistics are based on data collected from a large number of patients. The objective that these indexes are calculated and the methods to the calculation of these rates, may be different. According to available statistics, the survival rate of cancer of liver for five years after diagnosis, was around 9 per cent, a few years ago.
Age: according to the American Cancer Society, the average age of people diagnosed with liver cancer, was 66. Maximum (around 27 per cent) people diagnosed with liver cancer belonged to the 65-74 age group. Some 21 per cent people belonged to the age of 55-64 and 75-84 age group.
Gender and race: the survival rate of liver cancer was about 10.5% of white women, while it was about 7.5% of white men. For the men in black, was around 5.5 per cent while that for black women, which was around 4.5%.
Stages of liver cancer: these data can be divided again in the next section: localized stage: when it is detected liver cancer while it is still in the initial or localized stage, approximately 19% of people survive. The percentage of cases diagnosed in the initial phase is around 30%.
Apart from the parent site: about 6.5 per cent people survive when the cancer has spread beyond its original location, to the regional lymph nodes. 26% Cases are diagnosed when the cancer is in the second stage.
Cancer Metastasis: liver cancer survival rate is 3.5% when the cancer is at distant stage or when the cancer already has metastasized. Almost 22% of cases of liver cancer is diagnosed when the cancer has progressed to this distant stage.
No phase information: while the collection of data, it should be noted that some 22 per cent of cases diagnosed with liver cancer, information from the stage when diagnosed, is unknown. The survival rate for these cases it was found that approximately 3.4 per cent.
Liver transplantation: liver cancer survival rates are as high as 75%, after a liver transplant operation. But in developing countries, for the cases of more than 70%, surgery may not be considered a possible option, since liver cancer is often diagnosed when it is in the past or distant stage. Metastatic liver cancer survival rate is zero, and cancer will be transferred to the new liver, sooner or later. About 80% is the survival rate after transplantation of liver or liver cancer elimination, when the disease is diagnosed at an early stage.
Metastatic liver cancer: the age, General health, mind, availability of advanced treatments estada, affect the survival rate of metastasis of liver cancer. In fact, this type of survival is very rare. But still, with treatments advanced as embolization of chemotherapy and hepatectomy, around 55% patients can survive for 5 years.
Each case of cancer is a unique case. Statistics should not be used to guess what will happen to a person, who is fighting cancer. The rate of growth of a cancer is different in each affected person. People always opt for different treatments. The statistics are useful to scientists and medical research programs.
