Malignant Tumors 2007-10-28 15:11:47 Malignant Tumors are Cancerous Malignant tumors are created by the growth of cells that clump together to form a lump that does not have distinct borders especially at a later stage of it’s development when it will have roots that tend to stick out from the central lump. Tumors can develop in any part of the body. The one exception where cancers do not form a tumor is for Leukemia which is a cancer of the blood and organs that are responsible for the formation of blood including the lymph system, bone marrow and the spleen.
The cells that first begin to lump together create what is called the primary tumor. The grouping together of cells to form a cancerous tumor often takes place very slowly so that the tumor does not exhibit any detectable symptoms for many months or in some individuals or types of cancer, even for many years. Eventually though, the tumor will continue to develop and when it does one of two things will happen; the tumor will either spread (metastasize) or it will n Read more:Malignant
Benign Tumours 2007-10-28 15:09:26 Benign tumors are not cancerous In fact the word benign means harmless. A benign tumor is created by slower growing cells that clump together to form a lump that usually has a smooth surface. Benign tumors do not spread to other parts of the body and they are almost never life threatening. The only time that they could be life threatening is when they are located in an area of the body such as the brain where they could interfere with vital body functions.

Need a Diet Trend? 2007-10-28 15:07:27 Diet trends come and go in the United States, leaving Americans puzzled about what makes a sensible diet. While people may want to believe there is a quick fix, the best bet may be to tune out the hoopla and stick with Uncle Sam. The government probably knows best when it comes to recommending what we should eat. Indeed, most of its recommendations are backed by a wealth of science. Clearer recommendations, however, are needed about foods and dietary habits to avoid or limit.
The U.S. Department of Agriculture and the U.S. Department of Health and Human Services recently issued new Dietary Guidelines for Americans, with several key points to heed. First, the suggestion that Americans eat at least three servings of whole grains per day is essential to minimize disease risk. Many studies have shown that consuming whole grains, such as brown rice, whole wheat, and whole grain breakfast cereals instead of white rice, white bread, and refined grain cereals lower the risk of cardiovascular d
Are new treatments for mesothelioma being studied? 2007-10-28 14:58:57 Yes. Because mesothelioma is very hard to control, the National Cancer Institute (NCI) is sponsoring clinical trials (research studies with people) that are designed to find new treatments and better ways to use current treatments. Before any new treatment can be recommended for general use, doctors conduct clinical trials to find out whether the treatment is safe for patients and effective against the disease.

How is mesothelioma treated? 2007-10-28 14:57:33 Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient’s age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined.
* Surgery is a common treatment for mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.

How is mesothelioma diagnosed? 2007-10-28 14:53:24 Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. Diagnosis begins with a review of the patient’s medical history, including any history of asbestos exposure. A complete physical examination may be performed, including x-rays of the chest or abdomen and lung function tests. A CT (or CAT) scan or an MRI may also be useful. A CT scan is a series of detailed pictures of areas inside the body created by a computer linked to an x-ray machine. In an MRI, a powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.

What are the symptoms of mesothelioma? 2007-10-28 14:50:22 Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms
of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.

Who is at increased risk for developing mesothelioma? 2007-10-28 14:49:14 Asbestos has been mined and used commercially since the late 1800s. Its use greatly increased during World War II. Since the early 1940s, millions of American workers have been exposed to asbestos dust. Initially, the risks associated with asbestos exposure were not known. However, an increased risk of developing
mesothelioma was later found among shipyard workers, people who work in asbestos mines and mills, producers of asbestos products, workers in the heating and construction industries, and other tradespeople. Today, the U.S. Occupational Safety and Health Administration (OSHA) sets limits for acceptable levels of asbestos exposure in the workplace. People who work with asbestos wear personal protective equipment to lower their risk of exposure.

What are the risk factors for mesothelioma? 2007-10-28 14:46:25 Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos.
Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestos has been widely used in many industrial products, including cement, brake linings, roof shingles, flooring products, textiles, and insulation. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhaled or swallowed, and can cause serious health problems. In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney.

How common is mesothelioma? 2007-10-28 14:42:38 Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.
