Diagnosis of Mesothelioma

Diagnosis of Mesothelioma

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.

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

Symptoms of Mesothelioma

Symptoms of mesothelioma often do not appear for 20 to 50 years after initial exposure to asbestos occurred. Mesothelioma symptoms often resemble less-serious conditions, which can make a diagnosis of mesothelioma difficult. Below is a list of several common symptoms mesothelioma patients may experience.

Pleural Symptoms: Shortness of breath, chest pain, persistent cough, fatigue, lumps under the skin on the chest

Peritoneal Symptoms: Weight loss, abdominal pain and swelling, bowel obstruction, nausea

Pericardial Symptoms: Heart palpitations, irregular heartbeat, chest pain, difficulty breathing, night sweats

Testicular Symptoms: Painful or painless testicular lumps

Types of Mesothelioma

There are five known types of mesothelioma. The four listed below are malignant cancers, and benign mesothelioma is a non-cancerous condition.

Once asbestos is inhaled it can effect many of the bodys different organs including the throat, lungs, stomach, heart and testicles.

Pleural Mesothelioma: This type of mesothelioma develops in the lining of the lungs, known as the pleura. It is the most common form of malignant mesothelioma, with around 70 percent of cases being pleural in origin.

Peritoneal Mesothelioma: Comprising approximately 25 percent of mesothelioma cases, this form of mesothelioma develops in the lining of the abdominal cavity, known as the peritoneal membrane.

Pericardial Mesothelioma: This form of mesothelioma develops in the lining of the heart, known as the pericardium. Approximately 5 percent of all mesothelioma cases are pericardial.

Testicular Mesothelioma: Testicular mesothelioma develops in the tunica vaginalis of the testicles and is the rarest form of the cancer.

Introduction

Mesothelioma is a type of cancer that affects the lining of the lungs, heart and abdomen. More number of cases from 1000 to 3000 cases of mesothelioma are diagnosed each year in the United States which occupies some percentage of all types of cancer and is frequently affects more males than females.

Cancers are of generally 2 types one is benign and another is carcinogenic. Benign forms of all tumors or cancers including mesothelioma are generally not fatel whereas the other form is usually fatel unless otherwise found early.
It is reported as life expectancy after diagnosis.

For mesothelioma it is generally less than 1 percentage.
