What is involved in an angiosarcoma?
An angiosarcoma is a malignant form of cancer. Like most forms of cancer it is where a cell begins to cease higher functions and replicates itself causing damage to nearby cells.
When did David Chappe die?
David Chappe died on May 13, 2002, in Los Angeles, California, USA of angiosarcoma.
What type of tissue gives rise to sarcoma?
Sarcomas are malignancies that arise from mesenchymal tissues: (think of middle layers of body) bone, cartilage, muscle, fat, blood vessels. Examples are osteosarcoma-bone, chondrosarcoma-cartlilage, liposarcoma-fat, myosarcoma-muscle, and angiosarcoma-blood vessel.
What is subcentimeter hypodensity of the liver?
my ct scan says that i have several small focal hypodensities largest being 2cm this finding is non specific but these do not represent simple cysts. can anyone tell me what this means? This means that the scan picked up small areas of your liver that are different than the rest of the liver which puts up a "red flag" to the doctors. They know they are not simple cysts,therefore they must do further investigations to determine why these areas show up as denser than the surrounding tissue. Blood tests and possible biopsy (removing a small piece of the dense area) would be ordered. A liver biopsy is done outpatient and takes only a few minutes. Not to worry too much as fatty infiltration or hemangiomas can cause these findings, neither of which are unusual.Tissue in the liver that is less dense than the normal liver tissue, often fat.
Understanding the Causes, Symptoms and Treatments of Liver Cancer?
As the name indicates, liver cancer occurs primarily in liver cells. There are three known forms of liver cancer. Hepatocellular is the most common of the three forms, starting in liver tissues. Bile duct cancer accounts for up to 20 percent of liver cancer cases, affecting the ducts that carry bile to the gallbladder. Angiosarcoma is the rarest form that starts in the liver's blood vessels. Worldwide, liver cancer ranks third as the most common cancer, affecting nearly 700,000 people.Causes and RisksMen are more susceptible to getting liver cancer than women, accounting for more than three fourths of cases. People with a chronic infection of hepatitis B virus (HBV) or hepatitis C (HCV) have an increased risk of getting liver cancer. Other risk factors include: Cirrhosis, a progressive scarring of liver tissue; diabetes; excessive alcoholic drinking.Symptoms and DiagnosisTypically, symptoms of liver cancer are not apparent during the early stages. When symptoms do occur, most people will experience a loss of appetite and weight; abdominal pain in the upper part of the body; physical fatigue and weakness; swelling in the abdomen; nausea and vomiting; stools with a white, chalky texture; and, jaundice in the eyes.Diagnosis of liver cancer does not occur with routine blood tests. Most cases occur with people who have cirrhosis, which can lead to abnormal blood tests. Rather, doctors usually screen for liver cancer with a tumor marker and radiology imaging. Often, liver cancer is not diagnosed until symptoms begin to occur and effective treatment options diminish.Treatment OptionsAvailable treatment options largely depend on the stage of liver cancer and the overall health of the patient. The only known cure for this cancer is a liver transplant. Nevertheless, there are a few treatment plans for patients that a cancer care team develops. Some patients may undergo surgery to remove the part of the liver that is cancerous. Like most cancers, chemotherapy and radiation are used if anticipated results seem positive. Innovative treatments include freezing the cancer cells. An injection of liquid nitrogen into the tumors on the liver destroys these cells. Alternatively, an electrical heat current might also destroy the cancer cells.
Diagnosing The Causes Of Liver Cancer?
The exact cause of primary liver cancer remains unclear. Cancer in the liver occurs when the organ's cells mutate to such a degree than rapid division of identical cells begins. Over time these cells grow into a tumor, the liver functions begin to deteriorate and the entire body is affected in a negative manner. Medical experts have linked chronic hepatitis to the development of liver cancer cells, but much more study is needed to explain this relationship.Development of Primary Liver CancerSeveral different categories of liver cancer have been classified by the medical community. These are divided according to the location and type of cells that become cancerous. A hepatocellular carcinoma is the most common form of the disease. Hepatocytes are the cells making up the main tissue of the liver. Bile ducts are sometimes mutated, forming small tumors. This is known as cholangiocarcinoma. Liver cancer can also develop in the blood vessels supplying nutrients to the organ. This type of cancer is called angiosarcoma. Infants and toddlers sometimes become afflicted with a certain type of cancerous growth in the liver. This is called hepatoblastoma and its cause is unknown.Risk Factors For Liver CancerAlthough reasons for the mutation of liver cells remains somewhat of a mystery there is a mound of evidence pointing to certain risk factors. Age is one of the primary factors where liver cancer is concerned. In most of the developed nations the disease is very rare in individuals under the age of 45. Also males are more likely to develop liver cancer than females. Genetics may also play a role in the likelihood of scar tissue development in the liver. Known as cirrhosis, this condition is irreversible and often leads to primary liver cancer. Excessive alcohol consumption can cause damage to liver cells. Over a period of many years the cells will begin to undergo mutations and a malignant growth is possible.Aflatoxins ExposureThis has become a widely discussed topic in recent years. Evidence has shown that these toxins, present in certain fungi contained in corn, peanuts and other crops can lead to serious liver damage. Many countries now require treatment of food crops to reduce levels of aflatoxins. Regular testing of food samples is required in the United States.Other health problems such as diabetes can also increase the chances of primary liver cancer. Excessive buildup of fatty acids in the liver is also noted as a risk factor for the disease.
