Diagnosis of mesothelioma at its early stages can be a challenge even for the most experienced oncologists. Referred as asbestos cancer, this rare and aggressive disease is directly related to asbestos exposure. Mesothelioma affects the tissue that is surrounding the lungs, heart and abdominal cavity.
Mesothelioma Symptoms
The first signs indicating mesothelioma appear 30 to 50 years after the initial exposure to asbestos, and most of them are similar to those induced by pneumonia, asthma, bronchitis and other common illnesses. The main symptoms of pleural mesothelioma include:
Fever
Difficulty swallowing
Pleural effusion (fluid in the chest cavity)
Cough
Shortness of breath
Chest pain
Hoarseness
Weight loss
This form of cancer accounts for 75 percent of all cases, causing intense pain.
Less than 20 percent of those who develop asbestos cancer are diagnosed with peritoneal mesothelioma. This disease is very rare and attacks the lining surrounding the abdomen. The most common signs indicating peritoneal mesothelioma include:
Digestive disturbances
Bowel obstruction
Elevated white blood count
Ascites (fluid in the abdomen)
Loss of appetite
Weakness
Anemia
Abdominal pain
Pericardial mesothelioma accounts for less than 10 percent of all cases. This form of cancer is extremely rare and attacks the heart's serous lining. Approximately 200 people worldwide are diagnosed with pericardial mesothelioma each year. People who suffer from this disease usually present:
Heart palpitations
Irregular heartbeat
Severe chest pain,
Fluid retention in the legs
Difficulty breathing
Night sweats
Low blood pressure
Fatigue
Tests and Diagnosis
If the patient presents any of the signs described above, the doctor will order a computerized tomography (CT) scan, a chest X-ray, or a biopsy. He will also check for symptoms and possible risk factors and perform imaging test to find areas that might be cancerous. If mesothelioma is detected in the early stages, the patient's life expectancy increases significantly.
Diagnosing this aggressive form of cancer can be done using PET scans, lung function tests, blood tests, and immunohistochemistry tests. The doctor may also order a laparoscopy to check for tumors, take out organs or do a biopsy. Depending on the doctor's recommendations, mesothelioma patients will undergo a thoracoscopy, a mediastinoscopy or a bronchoscopy. A chest X-ray can reveal the accumulation of fluid in the lungs, while a computed tomography (CT) test will detect any signs of chest wall invasion or pleural effusion.
If the doctor finds any abnormal tissue, he will do a biopsy. To diagnose peritoneal mesothelioma, the specialist will use a peritoneoscope to look inside the abdomen. One of the most popular tools for diagnosing mesothelioma is video-assisted thoracic surgery. This minimally invasive procedure allows doctors to do biopsies of the pleural fluid, nodules, masses and pleural lining by making small incisions through the chest wall. Most tests are done in the hospital with a local anesthetic.
For most patients diagnosed with mesothelioma, the medical bills are overwhelming. If your illness has been caused by exposure to asbestos, or if you'd like to know more about mesothelioma, please fill out our mesothelioma packet form.
