Because mesothelioma often shows symptoms similar to other illnesses and because mesothelioma symptoms rarely show until after the disease reached its advanced stages, What is Mesothelioma Diagnosis because diagnosing mesothelioma is often hard. The process requires a more careful assessment of patient’s history, clinical and radiological findings, and biopsy.
Diagnosing mesotheliama begins with physical examinations, and review and analysis of the patient’s medical history including exposure to asbestos. This is followed by one or more clinical and radiological tests.
Imaging technologies are very valuable when it comes to diagnosing possible What is Mesothelioma Diagnosis mesothelioma since they can show possible abnormalities in the body such as fluid and mass formations.
- X-rays can show presence of fluid effusion, mass, and signs of non-cancerous asbestos-related diseases such as asbestosis and pleural plaques.
- CT or Computed Tomography Scans can show detailed images of mesothelial effusions, thickening of walls, invasions of chest walls, and in guiding fine needle aspiration tests. However, CT scans are unable to differentiate between benign asbestos disease and
- MRI or Magnetic Resonance Imaging can show severity of tumor by taking photographs of the inside details of the body using a computer-linked magnet. MRI can also show if there is enlargement of lymph nodes between the lungs and images of the diaphragm— two important elements that can determine if patient is candidate for surgery.
- PET or Positron Emission Tomography is now considered the most reliable in diagnosing tumor sites, and in finding out the staging of cancer.
Fluid sampling What is Mesothelioma Diagnosis
While imaging techniques are important in determining suspicious cell formation, lab tests of fluid and tissue samples are almost always needed to establish definitive diagnosis of cancer.
As tumor begins to thicken the walls of an organ, fluid builds up between the
walls. If fluid shows in the mesothelial area through MRI, this is the first
indication of possible mesothelioma. Fluid sampling is done to determine
positivity of cancer cells in the fluid. There are two known fluid sampling
procedures used in mesothelioma diagnosis.
- Peritoneoscopy involves the use of a tool known as peritoneoscope inserted into an opening made inside the patient’s abdomen in order to determine presence of peritoneal mesothelioma. In case presence of fluid is detected, a needle will be inserted into the abdomen to drain the fluid using a process known as paracentesis.
- To determine pleural mesothelomia, your physician may use thoracoscopy. First, an incision will be cut across the patient’s chest. A thoracoscope will then be inserted and placed between the ribs. If fluid is detected, fluid will be drained out using a needle then tested for presence of cancerous cells.
Sometimes, fluid sampling is still followed by biopsy. Fluid samples are
often inadequate in determining the type of cancer cells present. Biopsy is done
by removing a tissue sample then studying it under a microscope. Depending on
where the abnormality is located in the body, a biopsy may be done as:
- pleural biopsy, wherein the surgeon will make a small opening through the chest wall, then remove a tissue using a tool called thoracoscope;
- peritoneal biopsy, which involves making a small incision in the abdomen, then removing a tissue sample using a peritoneoscope.
