How is mesothelioma diagnosed?Diagnosis begins with a review of the patient's medical history, including any history of asbestos exposure. A complete medical history (interview) is taken to check for risk factors and symptoms. This will include questions to determine if you have been exposed to asbestos. People with mesothelioma usually experience shortness of breath, chest pain or pain or
swelling in the abdomen. At this point, the doctor may order an X-ray of your chest or abdomen, which may reveal fluid or other abnormalities warranting further examination in a hospital. CT scans of the chest and abdomen help in the diagnosis and staging along with a biopsy. MRI may also be useful. 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.
A physical exam will provide information about signs of mesothelioma and other health problems. Patients with pleural mesotheliomas (mesotheliomas of the chest) often have pleural effusion (fluid in their chest cavity) caused by the cancer. Ascites (fluid in the abdominal cavity) in cases of peritoneal mesothelioma, and pericardial effusion (fluid in the pericardium) in cases of pericardial mesothelioma can also be detected during a physical exam. Rarely, mesothelioma can appear in the groin and look like a hernia.
A biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity. If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.
If the diagnosis is mesothelioma, the doctor will want to learn the stage (or extent) of the disease. Staging involves more tests in a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment. Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs.
More information on mesothelioma cancerWhat is mesothelioma cancer? - Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order.
What types of mesothelioma are there? - Mesotheliomas consist of two general types-benign and malignant. Malignant mesothelioma is a cancerous tumor of the pleura.
What is pleural mesothelioma? - Pleural mesothelioma is a cancer of the cells that make up the pleura or lining around the outside of the lungs and inside of the ribs.
What is peritoneal mesothelioma? - Peritoneal mesothelioma is a cancer affecting the abdominal lining, or peritoneum. Peritoneal mesothelioma is a tumor of this membrane.
What is malignant mesothelioma? - Malignant mesothelioma is a cancer in which cancer (malignant) cells are found in the sac lining the chest (the pleura) or abdomen (the peritoneum).
What causes mesothelioma? - Asbestos exposure is the main cause of mesothelioma. The chances of suffering from mesothelioma rise with the intensity and duration of exposure to asbestos.
What're the risk factors for mesothelioma? - The main risk factors for malignant mesothelioma is exposure to asbestos. Other risk factors include radiation, zeolite, tobacco, and SV40 Virus.
Who's at increased risk for developing mesothelioma? - Family members and others living with asbestos workers have an increased risk of developing mesothelioma.
Asbestos and mesothelioma - Asbestosis, mesothelioma, and lung cancer are the three most frequent causes of death and disease among people with heavy asbestos exposure.
Where is asbestos found? - Asbestos has been widely used in many industrial products. Exposure to asbestos can occur in home improvement and construction projects.
When is asbestos dangerous? - Asbestos is hazardous when it is friable. The most common way for asbestos fibers to enter the body is through breathing.
How to reduce asbestos exposure? - Reducing exposure to asbestos by repairing damaged material will involve covering the material or sealing asbestos material.
What's the mesothelioma survival rate? - Mesothelioma is a serious disease. The average age at diagnosis is 50 to 70 years old. The average survival time is about one year.
What're the symptoms of mesothelioma? - Symptoms of mesothelioma include pain in the lower back or at the side of the chest, cough, fever, sweating, fatigue, and weight loss.
How is mesothelioma diagnosed? - Diagnosis of mesothelioma begins with a review of the patient's medical history, including any history of asbestos exposure.
How is mesothelioma staged? - Staging of mesothelioma is based on imaging studies such as x-rays, CT scans, and MRI scans. Malignant mesothelioma moves through four stages.
What's the treatment for mesothelioma? - Treatment for mesothelioma cancer include surgery, radiation therapy, and chemotherapy. Surgery is a common treatment for mesothelioma.
Treatment of malignant mesothelioma by stage - Most patients with stage I mesothelioma have their cancer surgically removed by pleurectomy/decortication or extrapleural pneumonectomy.
Surgery for mesothelioma - Surgery for malignant mesothelioma can be aimed at long-term control of the cancer (aggressive surgery) or relief of symptoms (palliative procedures).
Chemotherapy for mesothelioma - Chemotherapy uses drugs to kill cancer cells. In mesothelioma, chemotherapy may be put directly into the chest.
Radiation therapy for mesothelioma - Radiation is useful because mesothelioma is made up of rapid growing cells and radiation is most effective on cells that divide rapidly.
How to prevent malignant mesothelioma? - The risk of malignant mesothelioma can be reduced by avoiding getting exposed to asbestos.
What's the prognosis of malignant mesothelioma? - The survival time after diagnosis of malignant mesothelioma is about one year. Prognosis for malignant mesothelioma depends on how early it is diagnosed.
What about the mesothelioma lawsuits? - Mesothelioma lawsuits are classified into two groups: personal injury, and wrongful death. Mesothelioma lawsuits usually seek compensation for medical costs.
Who is mesothelioma attorney (lawyer)? - The benefits of hiring a mesothelioma attorney are numerous. A mesothelioma lawyer is able to provide both advice and assistance.
