Mesothelioma - What is Mesothelioma?
A variety of conditions can cause symptoms such as breathlessness or chest pain. This is why the first step in diagnosing mesothelioma is to rule out other diseases.
Doctors conduct this by taking samples of fluid around the stomach or lung. They may also employ other tests such as an CT scan, MRI or PET scan.
Causes
Mesothelioma is a type of cancer that occurs in the tissues that connect the chest (pleural mesothelioma), abdomen or heart (peritoneal mesothelioma). The most common cause of mesothelioma lies in exposure to asbestos, which was once widely used in shipbuilding, construction and other industries. Inhaling asbestos fibres can cause mesothelioma. These fibres can cause tissue damage and irritation and can cause abnormal tumors. It can take between 20 and 50 years for mesothelioma development after exposure to asbestos.
Asbestos is an assortment of minerals made up of long, thin fibers that can be broken down into smaller pieces. These fibres are able to easily enter the lungs where they can be inhaled. They then can be lodged in the pleura, the lining surrounding the lungs. These can irritate lung tissue over time and cause tumors that are abnormal to develop. Mesothelioma is also caused by exposure to asbestos through secondhand sources, such as when workers brought home fibres on their clothing and equipment or contaminated materials like asbestos-containing insulation.
Shortness of breath, fatigue and coughing are common symptoms for mesothelioma patients. Other signs include chest pain swelling, difficulty swallowing, and a painful rash similar to hives. Mesothelioma is a rare condition in the United States, is diagnosed between 2,500 and every year 3,000 times.
The most common mesothelioma form begins in the pleura that covers the lungs as well as the chest wall. Other mesothelioma types may develop in the peritoneum that lines the stomach, intestines, and testicles.
A specialist in mesothelioma could suggest tests like xrays, CT scans, or MRI to look for signs of disease. A mesothelioma specialist, a surgical thoracic surgeon, or a medical oncologist could perform surgery, chemotherapy or radiation treatment. Sometimes, palliative treatments are offered to alleviate discomfort and other symptoms. GPs can also help in the diagnosis of mesothelioma by examining symptoms and offering guidance on how to manage the symptoms. If needed, they may refer you to an expert. For instance, they could refer you to a respiratory doctor to look into your breathing and other symptoms as well as to work with your mesothelioma physician.
Signs and symptoms
Mesothelioma symptoms may vary depending on the type of mesothelioma that you are suffering from. This is because mesothelioma varieties are categorized by where the cancer originates in the body and how it spreads.
Mesotheliomas can develop within the lining of the lungs (pleura), lining the heart (pericardium), or lining the abdomen (peritoneum). Symptoms of mesothelioma include chest pain, breathing difficulties, fluid accumulation and weight loss.
Asbestos fibers can cause irritation of the pleura (lung liner) and abnormal cells to grow. In time, these cells can grow uncontrollably into tumors. Mesothelioma could also affect other body parts with similar liner. This includes the abdominal cavity as well as reproductive organs.
Symptoms can take longer to show, which can lead to late diagnosis. Most often, patients are diagnosed with mesothelioma after it has advanced and is life-threatening. This is due to the fact that mesothelioma's latency time is 20-40 years between exposure and the manifestation of cancer.
There are three options for treatment for mesothelioma: surgery, radiotherapy and chemotherapy. The doctor will advise you on the treatment that is best for your particular situation. The type of treatment you receive is contingent on the extent to which your cancer has been able to spread.
Surgery: Doctors remove any cancerous tissue during an operation. They may also combine surgeries to treat mesothelioma. The type of surgery used depends on the location and extent of the mesothelioma.
Radiation: Doctors employ high-energy radiation, or other forms of radiation, to stop the growth of mesothelioma cells. This type of therapy can be given externally or internally.
Chemotherapy: Doctors may prescribe chemotherapy liquids or pills to shrink cancerous cells or to stop their spread. Chemotherapy is used alone or in combination with other treatments, such as surgery and radiation.

Diagnosis
In the past, doctors employed a variety of tests to diagnose mesothelioma. These tests include physical examinations as well as lab work, and imaging scans. They will also review the patient's medical as well as job background to determine if there are asbestos exposure symptoms.
The first step to diagnosing mesothelioma is a physical examination by a physician. This involves looking for lumps and asking about the patient's symptoms. Doctors also look for the patient's mesothelioma type that includes epithelial, sarcomatoid or biphasic. These types are based upon the cells that make up each kind of cancer.
Mesothelioma can be hard to detect. It usually affects the pleura, which is thin layers of tissues that cover the chest cavity and lungs. It may also affect the peritoneum, a thin layer of tissue that lines the stomach and the intestines. A slurred breath, coughing, and abdominal pain are just a few possible symptoms. In some instances mesothelioma can be spread to other organs, including the heart.
A biopsy is the most reliable method to confirm mesothelioma. A doctor will send a tiny mesothelioma sample to a lab for testing. The laboratory looks for mesothelioma cancer cells as well as other types of cancer.
If the biopsy results are positive for mesothelioma, doctors will test to determine the kind of cancer cells. This allows them to select the most appropriate treatment.
Other tests include an X scan or CT scan to look for asbestos in the lung lining as well as calcium deposits or signs of Mesothelioma such as a pleural effusion. They may also run blood tests to see whether there are any abnormalities such as anemia, or low levels of certain antibodies, which indicate mesothelioma.
Other imaging tests include an MRI or PET scan, which uses radio waves and magnets to produce precise images of the soft tissues in the body. They can help doctors detect mesothelioma on the lungs, and in other areas such as the diaphragm muscle (a dome-shaped muscle tissue that separates the chest from the abdomen). They can also show the extent of the cancer's spread. They may also test the lymph nodes for signs of mesothelioma. This is done by putting an instrument in the trachea, or windpipe. This procedure is referred to as mediastinoscopy and is done under the influence of sedation.
Treatment
Mesothelioma is difficult to treat because the cancer is often diagnosed late and spreads by the time it is found. Treatment focuses on reducing symptoms and improving quality of life. A mesothelioma specialist can assist people find the right treatment program for them.
A mesothelioma specialist will have a team of specialists working together to provide treatment. The team could include a general practitioner who is responsible for the overall health of the patient as well as a respiratory doctor who examines symptoms and treats lung disease and an interventional radiologist who uses imaging scans for guiding needles and other tools for draining fluids or removing tissues to diagnose, a surgeon who performs surgery or other operations to treat lung diseases or the chest as well as a medical oncologist that prescribes drugs such as chemotherapy.
If mesothelioma has been discovered, further tests will be conducted to determine if the cancer has spread to other areas of the body. This may include an CT scan or MRI, FDG-positron emissions tomography (to search for the movement of the mesothelioma tumor cells) and a biopsied sample taken from a tissue sample taken during surgery.
A patient suffering from malignant pleural mesothelioma is likely to undergo a surgical procedure in order to relieve breathlessness due to fluid buildup. This might involve a procedure called VATS (video-assisted thoracoscopic surgery) where a portion of the lining of the lung and chest wall are removed to reduce fluid build up. In what is mesothelioma symptoms some cases the fluid may be drained regularly at home by using a tube put into the chest.
Benign mesothelioma is not typically require surgery. Instead, doctors might opt to use palliative treatments like painkillers to ease symptoms or look into other treatments that don't require surgery.
Clinical trials are conducted to test mesothelioma, a rare cancer and under investigation, is being tested. These trials could result in improved treatments for mesothelioma patients. However the decision to take part in a trial should not be taken lightly as the risks of treatment are often very severe. It is essential that those suffering from mesothelioma or their families consider their options with an expert.
