Description

Liver Cancer Liver cancer is cancer that begins in the cells of your liver. Your liver is a football-sized organ that sits in the upper right portion of your abdomen, beneath your diaphragm and above your stomach. Liver cancer is cancer that occurs in the liver. The liver is the largest glandular organ in the body and performs various critical functions to keep the body free of toxins and harmful substances. It’s responsible for producing bile, which is a substance that helps you digest fats, vitamins, and other nutrients. This vital organ also stores nutrients such as glucose, so that you remain nourished at times when you’re not eating. It also breaks down medications and toxins. When cancer develops in the liver, it destroys liver cells and interferes with the ability of the liver to function normally. Liver cancer is generally classified as primary or secondary. Primary liver cancer begins in the cells of the liver. Secondary liver cancer develops when cancer cells from another organ spread to the liver. Unlike other cells in the body, cancer cells can break away from the primary site, or where the cancer began. The cells travel to other areas of the body through the bloodstream or the lymphatic system. Cancer cells eventually collect in another body organ and begin to grow there. Cancer happens when liver cells develop changes (mutations) in their DNA. A cell's DNA is the material that provides instructions for every chemical process in your body. DNA mutations cause changes in these instructions. One result is that cells may begin to grow out of control and eventually form a tumor — a mass of cancerous cells. Several types of cancer can form in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the main type of liver cell (hepatocyte). Other types of liver cancer, such as intrahepatic cholangiocarcinoma and hepatoblastoma, are much less common. Cancer that spreads to the liver is more common than cancer that begins in the liver cells. Cancer that begins in another area of the body — such as the colon, lung or breast — and then spreads to the liver is called metastatic cancer rather than liver cancer. This type of cancer is named after the organ in which it began — such as metastatic colon cancer to describe cancer that begins in the colon and spreads to the liver. There are stages of liver cancer. One thought you might have when you hear that you have cancer is, “Has it spread?” The doctor uses a process called staging to give the cancer diagnosis a number from I to IV. The higher the number, the more cancer has a chance to spread. Cancers are also defined by how they can be treated, mostly by deciding if cancer can be removed by surgery. Liver cancer stages include the following; Stage I: One tumor is found in the liver only, Stage II: One tumor is found, but it has spread to the blood vessels, OR more than one tumor is present, but they are all smaller than 3 cm, Stage III: In Stage III liver cancer, there is more than one tumor and one of them at least is larger than 5 cm, OR the cancer has moved beyond the liver to large blood vessels, another organ, or to the lymph nodes, Stage IV: The cancer has spread to other places in the body, such as the lungs or bones, as well as lymph nodes. Liver cancer that has returned may also be called recurrent. Recurrent liver cancer could come back in the liver or anywhere else in the body.

Most people don't have signs and symptoms in the early stages of primary liver cancer. When signs and symptoms do appear, they may include losing weight without trying, loss of appetite, upper abdominal pain, nausea and vomiting, general weakness and fatigue, abdominal swelling, yellow discoloration of your skin and the whites of your eyes (jaundice), White, chalky stools, and disoriented. Sometimes the cause of liver cancer is known, such as with chronic hepatitis infections. But sometimes liver cancer happens in people with no underlying diseases and it's not clear what causes it. Factors that increase the risk of primary liver cancer include Chronic infection with HBV or HCV. Chronic infection with the hepatitis B virus (HBV) or hepatitis C virus (HCV) increases your risk of liver cancer, Cirrhosis. This progressive and irreversible condition causes scar tissue to form in your liver and increases your chances of developing liver cancer. Certain inherited liver diseases. Liver diseases that can increase the risk of liver cancer include hemochromatosis and Wilson's disease. Diabetes. People with this blood sugar disorder have a greater risk of liver cancer than those who don't have diabetes. Nonalcoholic fatty liver disease. An accumulation of fat in the liver increases the risk of liver cancer. Exposure to aflatoxins. Aflatoxins are poisons produced by molds that grow on crops that are stored poorly. Crops, such as grains and nuts, can become contaminated with aflatoxins, which can end up in foods made of these products. Excessive alcohol consumption. Consuming more than a moderate amount of alcohol daily over many years can lead to irreversible liver damage and increase your risk of liver cancer. In order to prevent liver disease, Reduce your risk of cirrhosis. Cirrhosis is scarring of the liver, and it increases the risk of liver cancer. You can reduce your risk of cirrhosis if you. Drink alcohol in moderation, if at all. If you choose to drink alcohol, limit the amount you drink. For women, this means no more than one drink a day. For men, this means no more than two drinks a day. Maintain a healthy weight. If your current weight is healthy, work to maintain it by choosing a healthy diet and exercising most days of the week. If you need to lose weight, reduce the number of calories you eat each day and increase the amount of exercise you do. Aim to lose weight slowly — 1 or 2 pounds (0.5 to 1 kilograms) each week. Get vaccinated against hepatitis B. You can reduce your risk of hepatitis B by receiving the hepatitis B vaccine. The vaccine can be given to almost anyone, including infants, older adults and those with compromised immune systems. Take measures to prevent hepatitis C. No vaccine for hepatitis C exists, but you can reduce your risk of infection. Know the health status of any sexual partner. Don't engage in unprotected sex unless you're certain your partner isn't infected with HBV, HCV or any other sexually transmitted infection. If you don't know the health status of your partner, use a condom every time you have sexual intercourse. Don't use intravenous (IV) drugs, but if you do, use a clean needle. Reduce your risk of HCV by not injecting illegal drugs. But if that isn't an option for you, make sure any needle you use is sterile, and don't share it. Contaminated drug paraphernalia is a common cause of hepatitis C infection. How is liver cancer diagnosed? Your doctor may think about liver cancer if they find lumps or other symptoms during your physical exam. The doctor might order other tests, like: Blood

tests: A serum marker test measures the amounts of certain substances linked to cancer. For liver cancer, cirrhosis, and hepatitis, the substance alpha-fetoprotein (AFP) may show up in higher levels. AFP in high levels is considered a tumor marker. Liver enzyme tests that show high levels of liver enzymes may also point to liver disease. This test provides pictures of your soft tissue structures. Ct Scan, this special type of X-ray takes detailed images of organs. MRI, this test produces very clear images of the human body using a large magnet, radio waves, and a computer. Angiogram During this test, a dye is injected into an artery to show liver tissue and any tumors. Laparoscopy the doctor uses a thin tube with a light (laparoscope) to observe the liver and other organs inside the stomach area. Biopsy is the removal of tissue for study under a microscope. It may be done using a laparoscope. A biopsy is the most reliable way to determine cancer. If you have liver cancer, your treatment and chance of recovery (also called prognosis) may depend on certain things. These include your general health, how well your liver is working, the stage of the cancer that you have and your levels of alpha-fetoprotein. Liver cancer may be treated using one or more methods: surgery, loco-regional therapy, different types of drug therapy, and even liver transplantation. A liver cancer diagnosis can be overwhelming. It’s important to have a strong support network that can help you deal with any stress or anxiety you may be feeling. You may want to see a counselor who can help you work through your emotions. You might also want to consider joining a cancer support group where you can discuss your concerns with others who can relate to what you’re going through....
