Mesothelioma Asbestosis

Mesothelioma and asbestosis are caused by exposure to asbestos. Both are long-term issues. Mesothelioma, which is a cancerous disease, is different from asbestosis.

A biopsy is the most common way to diagnose mesothelioma pleural. Doctors take a small amount of pleural tissue and study it under a microscope.

Signs and symptoms

Mesothelioma is a type of cancer that affects the thin layer of tissue that covers organs. It can be caused by exposure to asbestos claim. Asbestos is made up of mineral fibers which are naturally occurring. It was used to create a variety of products including insulation, brakes and flooring. When asbestos claim is disturbed, tiny fibers are released into the air. Inhaling these fibers can cause irritation to the stomach and lungs. Mesothelioma is a condition that occurs when the cells of the affected tissue begin to grow abnormally and turn into tumors. Mesothelioma is a cancer that can be found in both females and males.

The symptoms can vary depending on the location the tumors grow and the stage mesothelioma cancer is. The most common symptoms are breathing difficulties and chest pain. Other signs include abdominal discomfort, fatigue and fever. After asbestos exposure mesothelioma can take up to 60 years to be diagnosed. Symptoms often don't appear until the disease is in an advanced stage. This lengthy latency time is one of the main reasons patients are misdiagnosed.

The first signs of pleural mesothelioma include a cough, difficulty breathing and chest pain. As the cancer grows it can result in fluid buildup that irritates the lungs and causes coughing, chest wall pain fatigue, and weight loss. Fluid buildup can also happen around the heart or in the abdomen.

As the disease progresses, symptoms become more severe and are spread to other parts of the body. Peritoneal mesothelioma may cause pain in the abdomen and cause digestive problems. Pleural mesothelioma can extend to the chest wall, diaphragm or the heart, causing lung problems.

Doctors are able to diagnose mesothelioma through taking a sample of tissue known as a biopsy. They will examine the tissue for abnormal cells and determine the type of mesothelioma: epithelioid, sarcomatoid or biphasic mesothelioma. Epithelioid mesothelioma accounts for 70% of diagnoses, and is the most responsive to treatment. Sarcomatoid mesothelioma has a poorer prognosis and is more difficult to treat. Biphasic Mesothelioma is distinguished by both epithelioid (epithelioid) and sarcomatoid (sarcomatoid) cells. It is seen in 40% of patients. The early stages of the disease should be treated surgically.

Diagnosis

The diagnosis of mesothelioma is dependent on a mix of tests, such as imaging scans and blood tests. The test results can be used to determine whether there are any mesothelioma tumors present and assist doctors in deciding on the most appropriate treatment option for each patient.

A doctor will first assess the patient and ask them about their exposure to asbestos in the past. Those who have been exposed to asbestos likely are aware that they are at risk of developing lung issues, but often it takes years before symptoms start to manifest. Many patients with mesothelioma have been misdiagnosed as having lung cancer or pneumonia.

Mesothelioma is triggered by the inhalation of tiny fibres of asbestos, which damage the lungs and other organs. The damage is slow to manifest, with the earliest signs of mesothelioma usually not showing up until 20 to 60 years after exposure.

Asbestos is a group of minerals that are made of microscopic fibres. They were used in the construction of buildings but are now banned. Those who have worked in mining and manufacturing in which asbestos might be inhaled or handled, are at the highest risk of developing mesothelioma. This includes insulation and mining workers as well as electricians, builders and other construction workers.

Once the doctor has completed their initial examination typically, they will require a variety of imaging tests to obtain more specific information about the extent of the mesothelioma. CT (computerised Tomography) scans are available, as are MRI (magnetic-resonance imaging) and PET scans. These scans can help determine the location of mesothelioma tumors and if they've spread.

Doctors will also take an x-ray of the tissue in the affected area in order to confirm a mesothelioma diagnosis. This can be done either by inserting a needle during surgery. VATS (video assisted thoracoscopic surgis) or CT-guided core biopsies are commonly used for pleural mesothelioma. For peritoneal cancers, the sample is usually taken during surgery or using an syringe for cytology. The sample is then examined under microscopes to confirm the diagnosis of mesothelioma.

Treatment

Early diagnosis of mesothelioma can result in a successful treatment. Treatment options include chemotherapy, radiation therapy and surgery. Certain patients have also experienced good results from new targeted therapies, but these are still being tested in clinical trials.

Doctors will usually perform an examination of the body when they suspect mesothelioma. They can also request imaging scans, blood tests and a biopsy. A biopsy involves removing tissues or fluid from the affected area, such as a lung mass for examination under microscope. The doctor can conduct a biopsy through surgical methods such as VATS (Video-assisted thoracoscopic surgery), or by inserting a needle into the mesothelioma in order to remove a tiny piece of tissue.

In a biopsy, doctors will also take samples of tissue to be tested further in the region around the tumor. This will help them determine if the mesothelioma cells are cancerous, and what kind they are. They will use this information to determine the appropriate mesothelioma treatment.

The symptoms of mesothelioma can be severe and can make daily life difficult. They can be painful particularly if they press against organs or nerves. Mesothelioma may also cause fluid to build up in the abdomen or chest. This can lead to breathing difficulties or weight loss, as well as a swelling of the abdomen or chest.

For those who are too sick to undergo surgery, doctors can drain excess fluid to improve breathing and relieve chest pain. This is known as paracentesis or thoracentesis. They can also use pleurectomy or decortication. This involves injecting a sterile powder into the pleural cavity to cause inflammation and reduce the accumulation of fluid.

Peritonectomy is a method that is used by doctors to remove the tumor and part of the abdominal lining of peritoneal cancer. Doctors can also treat peritoneal mesothelioma with chemotherapy or radiation therapy alone or in conjunction with surgery. They can also administer chemotherapy prior to radiation or surgery, which is known as the neoadjuvant treatment. They can also try experimental treatments in clinical trials, such as a novel drug that targets the cell cycle.

Prognosis

The prognosis for mesothelioma will vary depending on a number of factors. The type of cancer, its location and stage can all influence how the disease progresses and the treatments that are utilized.

A biopsy will determine the type of mesothelioma a patient has. During this procedure it is a small amount tissue is removed from the area affected and examined under microscope. A pathologist will examine the tissue for any signs of mesothelioma and for other abnormalities.

A few signs that could suggest pleural mesothelioma include chest pain, breathing difficulties and chronic coughing. Patients who exhibit any of these symptoms should seek immediate medical treatment.

Mesothelioma can be difficult to diagnose, especially in its early stages. It is common to miss-diagnose patients. A second opinion from an expert in mesothelioma may increase the chances of a patient's survival. Getting a correct diagnosis means receiving the right treatment, which can dramatically increase the odds of survival.

A cytology test is an important element in diagnosing mesothelioma. This test involves taking a small amount from the lungs affected and abdomen, and then examined under a microscopical microscope to detect evidence of mesothelioma. The test will also reveal how cells are developing and help doctors determine the type of mesothelioma that an individual has.

Another lab test that is used to diagnose mesothelioma is immunohistochemistry. In this lab test, antibodies are used to attach to markers on the cells. When the antibody binds the marker the stain's color changes. The stain's color indicates what type of mesothelioma is displayed by the cells.

The oncologist will determine the extent of mesothelioma's growth after it has been identified. This is called the staging of mesothelioma. Stage 1 mesothelioma has the most likely to be successful and is followed by stages 2 and 3. The prognosis for people suffering from peritoneal or sarcomatoid mesothelioma is worse due to the fact that these cancer cells are more difficult to treat than epithelioid.

A doctor may suggest chemotherapy, radiation therapy or surgery after a mesothelioma diagnosis. Some doctors will also prescribe combinations of these therapies. Another treatment option that is possible is a mesothelioma vaccination which has shown promise in improving survival rates and slowing the progression of mesothelioma.
