INFORMATION ABOUT MESOTHELIOMA

INFORMATION ABOUT MESOTHELIOMA

A tumor of the tissue that lines lungs, stomach, heart and other organs. Cancerous or malignant mesothelioma is the most common form which usually effects the lungs. Three out of every four cases begin in chest cavity. This mesothelioma also begins in the abdominal cavity and around the heart. Malignant cells from mesothelium can invade and damage nearby tissues, and can also spread to other body parts.

WHAT ARE THE SYMPTOMS OF MESOTHELIOMA?

 The symptoms may vary depending on where the cancer occurs

 Pleural mesothelioma, affects the tissue that surrounds  the lungs, and the symptoms include:

  • Shortness of breath
  • Weight loss
  • Painful coughing (dry cough)
  • Pleural effusion
  • Chest pain
  • Fever
  • Night sweats
  • Muscle weakness
  • Lumps of tissue under the skin on chest

Peritoneal mesothelioma, occurs at the tissues of abdomen, symptoms may include:

  • Swelling of abdomen
  • Abdominal pain
  • Nausea
  • Weight loss

MESOTHELIOMA ICD 10 CODES:

Mesothelioma of Pleura – C45.0

Mesothelioma of Peritoneum – C45.1

Mesothelioma of Pericardium – C45.2

Mesothelioma of Other sites – C45.7

Mesothelioma, unspecified – C45.9

WHAT IS THE CAUSE OF MESOTHELIOMA?

Exposure to asbestos is the main cause of mesothelioma. Asbestos is naturally occurring mineral which is made up of flexible microscopic fibers. Continuous exposure to asbestos leads to development of mesothelioma. Types of asbestos exposures are Occupational, second handed and Environmental. Generally cancer occur due to mutations which happen in the cell of DNA. Due to these mutations in the DNA there will be abnormal growth which form tumor.

RISK FACTORS OF MESOTHELIOMA:

 Asbestos exposure is one of the primary risk factor for mesothelioma. A person inhales or swallows asbestos fibres,  over time exposure lead to tumor which damage mesothelium the lining of abdomen, lungs, heart and testes.

Asbestos is mineral found naturally in environment. The factors that increase the risk of mesothelioma are:

  • Personal history of asbestos exposure
  • Living with people who works with asbestos
  • Family of mesothelioma
  • Radiation therapy to chest

DIAGNOSIS OF MESOTHELIOMA:

  • Biopsy is the only test that confirm mesothelioma which include needle biopsy, thoracoscopy, laproscopy, mediastinoscopy, surgical biopsy, endobronchial ultrasound guided biopsy.
  • CT scan, PET scan( Positron emission tomography), X-Rays, MRI scan are also been used for the identification of mesothelioma.
  • Blood tests
  • Fluid and tissue sample tests

laproscopy

If the tumors are cancerous, then it is diagnosed as malignant mesothelioma.

The collection of the samples is done by various procedures such as thoracentesis for chest cavity, Paracentesis for abdomen and Pericardiocentesis for membrane around the heart.

STAGES OF MESOTHELIOMA:

 The stages of the mesothelioma are based on tumor size and location which range from 1 to 4.

STAGE 1: This is a localized cancer. Surgery is effective in this stage. Rate of survival is high.

STAGE 2:  In this stage the tumor start spread from the original location to adjacent. Surgery is one of the option.

STAGE 3: In this stage the cancer is still progressed to advanced stage which spread to regional lymph nodes. Surgery may be done.

STAGE 4:  In this stage cancer is spread extensively in area where it is developed. Chemotherapy is done which helps to prolong the survival.

TYPES OF MESOTHELIOMA CANCER:

 There are four types of mesothelioma cancer based on where the tumor is been developed in the body which include pleural, pericardial, peritoneal, testicular mesothelioma.

  Along with the mesothelioma cells there are three types of cells found in  mesothelioma tumors such as Epithelioia, sarcomatoid and biphasic.

 MESOTHELIOMA is treated by surgery, radiation therapy and chemotherapy.
