Mesothelioma - The Tests Used For Diagnosis

Cancer is a word that will scare even the bravest of folks. Mesothelioma is a form of cancer that is associated with asbestos exposure and is, fortunately, fairly rare. In this article, we take a look at the tests used for diagnosing it.
Unless you like reading Grey's Anatomy, you probably aren't aware of the significance of the name of this cancer. Mesothelioma refers to a cancer of the Mesothelium. Huh? The Mesothelium is a lining that surrounds the chest and abdomen cavities as well as the organs. There is a lubricant in the lining that allows the organs to move about without injury. Mesothelioma is a cancerous growth in this lining.
Testing for Mesothelioma is fairly difficult. The cancer can take 15 to 40 years to manifest after exposure to asbestos. The preliminary test is nothing more than the chest x-ray you get with your yearly checkup. The x-ray can reveal abnormal growths. It rarely conclusively shows Mesothelioma, but does give the physician a heads up that further investigation is needed.
The next test used to diagnose the condition is a Cytology test. This is done by taking out fluid in the Mesothelium lining. It is then analyze in a lab in an effort to determine if any malignant cells are present. This test is starting to be used less often by physicians. Why? It is notoriously inaccurate!
Now we start getting to the serious tests. The first is known as a needle biopsy. In this test, a needle will be inserted into what appears to be the area of concern. A small amount of material is then removed and sent to the lab for analysis. This is a direct test of the area in question and usually reveals conclusively what is going on. If the area in question is not readily available to a needle, the biopsy may be done as a full surgery where the area is opened up and a sample is taken.
One of the things people constantly complain about when it comes to cancer diagnosis is the lack of a definitive answer. Every test suggests something, but few definitely indicate anything. The same frustration holds true for Mesothelioma. Until you have a biopsy done, you'll never really know if you have this form of cancer.

Mesothelioma - New Treatment Approaches

A determination that you or someone close to you has Mesothelioma is very unfortunate. This form of cancer is usually discovered very late in its growth, which makes treatment extremely difficult and often renders it a terminal disease. There are, however, some new treatment approaches being researched.
Mesothelioma is a fairly rare cancer. It is general term that refers to cancer growths in the area of the Mesothelium. This is a lining found throughout the chest and abdomen area. The lining creates support for organs such as the lungs and heart while also creating a lubricated surface that allows them some movement. Mesothelioma is associated most closely with exposure to asbestos fibers that get into the lungs and then into the chest cavity.
The standard treatments for Mesothelioma are similar to other cancers. Radiation and chemotherapy are definite musts. Surgical procedures are also very common. Still, these three more often than not fail to overcome the cancer and death often occurs within one year of diagnosis. All is not lost. There are a number of new therapies being researched. Let's take a closer look.
Cancer is the mutation of the DNA in cells. Given this, Gene Therapy is a very new treatment being considered for use with Mesothelioma and most cancers. There are two approaches being investigated. The first is to replace the genetic structure of the cancerous cells and thus wipe out the cancer. The second approach is to use a knockout approach where genetic manipulation removes the genes that give rise to tumor growth. In theory, this would terminate tumor and cell growth and stop the cancer in its tracks.
Photodynamic therapy is as unique as it is hard to explain. There are certain chemicals that are very light sensitive. The body can absorb some of these chemicals into cells and then expel them. Cancerous cells, however, cannot expel the chemicals. A patient is given a dose and then the cells are exposed to a laser light. The chemicals kick out an active form of oxygen that destroys the cancerous cells. There is a downside, however. The patient becomes very light sensitive and often must stay out of the light for as long as six weeks.
Anti-angiogenesis treatment is another interesting area of treatment. It works by attacking the tumors created by Mesothelioma. It does this by eliminating the ability of the tumors to create blood vessels. Without such vessels, the tumors cannot get blood and cannot grow. Drugs such as Cisplatin, Pemetrexed and Bevacizumab are in clinical trials to determine if they can be used on Mesothelioma tumors.
Mesothelioma is a rare, but very serious form of cancer. While past treatment methodologies produced disappointing results, the new treatments being tried show some major promise. Make sure to discuss them with your oncologist and physician.

Mesothelioma - Dealing With Shortness of Breath

Mesothelioma is a fairly rare cancer that is associated with exposure to asbestos. The cancer manifests with many different symptoms depending on the stage it is in and the location of the body. In many cases, shortness of breath is one problem, but there are a number of ways to deal with it.

Mesothelioma is somewhat of a catch phrase for a certain type of cancer caused by asbestos exposure. It refers to a cancer of the Mesothelioma lining in the upper body. The problem is this lining is found everywhere from the sac surrounding the heart down to the organs in the lower abdomen. As a result, a diagnosis of Mesothelioma around the lower, far right lung is much different then the same diagnosis for the heart.

The vast number of Mesothelioma cases deal with cancer around the lung area. As a result, the lungs are often impacted in a couple of ways. The practical function many be disturbed, but the bigger problem is usually the embedding of small asbestos fibers in the alveoli where the air in the lungs is transferred into the blood. This can lead to shortness of breath for many patients.
Is there anything that can be done for shortness of breath in these situations? Yes. The first is to tell your doctor! He or she may prescribe medication or oxygen assisted breathing sessions to give you relief. You can take some practical steps as well. Meditation and yoga are excellent ideas as they help a person relax, which will reduce the taxation on your lungs. You should also consider sleeping on multiple pillows in an effort to get your head above the plain of your body. This will ease your breathing as well.

There is no cure per se to Mesothelioma, but early discovery can make the difference between living and dying. While the disease is deadly, that doesn't mean you have to suffer from some of the symptoms. Shortness of breath is one that can be dealt with if you make an effort.

Pericardial Mesothelioma - What You Need to Know

People perceive mesothelioma and asbestos-related diseases to affect only the lungs. Since mesothelioma is caused by inhalation of asbestos fibers, it is common to think that it only accumulates in the lungs. However, asbestos can affect the serous membranes which enclose other organs found in the mid-section of our body (not just the lungs) such as the heart, in a condition named pericardial mesothelioma.
Pericardial mesothelioma, also known as mesothelioma of the pericardium is the rarest type of asbestos-induced disease. As is suggestive of its name, this disease affects the linings of the heart or the pericardium. This variety of cancer only affects about 10% of mesothelioma patients. Despite continuous studies, there is no confirmatory evidence that explains how the asbestos fibers get lodged in the linings of the heart, although various theories have tried to explain the occurrence.
One theory proposes that the asbestos fibers, when inhaled, are broken down into smaller particles in the lungs, small enough for them to be carried into the blood stream and pumped into the heart. When this happens, the fine asbestos fibers become lodged in the linings, causing chronic inflammation which eventually leads to cancerous tumor growth.
As with other types of mesothelioma, pericardial mesothelioma can take a few decades to manifest. It usually takes twenty to thirty years, or even longer. This also means that when the cancer symptoms do manifest, it is almost always too advanced for curative treatment.
The most common symptoms to watch out for with pericardial mesothelioma include persistent coughing, shortness of breath, palpitations and chest pains. These are usually mistaken for less serious ailments, making it even more difficult to diagnose immediately. Once a diagnosis has been made by your doctor, the next step is usually to find out the extent of the spread of the cancerous cells. This is often done through an MRI or a CT scan, the results of which will determine the mode of treatment.
Pericardial mesothelioma can be treated through a range of treatment options. If the disease is found early on, surgery may be an option. However, as this disease is oftentimes detected in its late stages, more aggressive treatment combinations including chemotherapy and radiation are frequently involved. Clinical trials are being conducted on pericardial mesothelioma. Because of its rare nature, research studies on this type of asbestos-related cancer have been quite limited.

Mesothelioma Survival - What Are the Chances?

Every year, about 3000 new cases of mesothelioma are diagnosed in the United States alone. Unfortunately, mesothelioma is an aggressive and usually fatal type of cancer that results from asbestos exposure. This disease occurs when microscopic asbestos fibers are inhaled and get lodged into the linings of the lungs.
What are the chances for mesothelioma survival once a victim gets diagnosed? Sadly, not many victims of mesothelioma survive more than five years after the diagnosis has been made. Mesothelioma survival chances are increased if the disease is caught early. However, this kind of cancer is difficult to detect in its early stages. Once it is detected and diagnosed, it is oftentimes in its advanced stage and too late for a definitive cure. According to reliable sources, less than 10% of mesothelioma sufferers get the chance to survive more than 5 years, while about 40% of sufferers survive more than a year after diagnosis.
As in all forms of cancer, mesothelioma survival rates depend on various factors. These include:
* The current stage of the cancer. The stages of mesothelioma range from Stage One, which primarily means that the tumor is localized in the chest lining, to Stage Four, meaning that the tumor has spread to other vital organs.
* The histology (cell structure and type) of the cancer. Mesothelioma cancer can come as epithelial, which has better prognosis, sarcomatoid, biphasic or desmoplastic.
* The overall health condition and age of the sufferer. The malignant forms of mesothelioma are oftentimes diagnosed in sufferers above the age of 55. Generally, the older the victim is, or the more chronic illnesses associated with the disease, the less chance there is for mesothelioma survival.
* The size and location of the tumor (whether the tumor is operable or not.)
* The extent of the symptoms, such as whether fluid buildup has been observed in the lungs or abdomen.
Mesothelioma is a serious condition which demands immediate medical attention. Although there is no proven cure for mesothelioma, various treatment options are available to prevent the disease from spreading and also to reduce pain and suffering for the victim.
These treatment options may increase the chances for mesothelioma survival. According to various studies, victims administered with chemotherapy, radiation, or surgery, or a combination of any two or three, have a survival rate of at least 18 months after undertaking the procedures.
Today, many experimental treatments are being evaluated throughout the world in controlled clinical trials. These include Photodynamic Therapy, Immunotherapy, Heat Therapy and Gene Therapy.
