Mesothelioma and Other Asbestos Related Cancers
People with an exposure history to asbestos are at risk of developing various types of cancer such as mesothelioma. These diseases have a time-of-resistance of many years, meaning that symptoms may not be evident until decades after exposure.
The risk of developing pleural or peritoneal msothelioma declines after first exposure. Evidence is based upon two residential and six occupational cohort studies with long-term follow-up.
What is Mesothelioma?
Mesothelioma is a cancer of the internal organs' lining that include the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma) or the heart (pericardial mesothelioma). It is a rare and dangerous disease that typically starts in the lining of the chest cavity. However, it may also affect the lining in the stomach or other parts of your body. Asbestos exposure is the primary cause of mesothelioma, and the cancer is usually not able to show up until decades after the initial exposure.
People who are exposed to asbestos at work have higher chance of developing cancer than others. Asbestos fibres can be swallowed or inhaled and stick to the lining of the organ. The fibers can cause irritation to the lining of the organ and cause abnormal cells to multiply, leading to tumors. The symptoms usually do not show until a person has developed mesothelioma with advanced stage.
Most asbestos exposure occurs in industrial settings, where workers handle the substance or work close to it. Asbestos is utilized in a variety of trades, such as shipbuilding, construction and auto repair. Veterans who served in military are at greater risk of developing mesothelioma due to asbestos because it was extensively employed on bases and ships.
People with a history of asbestos exposure must have regular checks and be aware of any unusual symptoms. If a doctor suspects mesothelioma they could request imaging tests such as CT scans, MRI or PET scans to detect tumors and see whether they've expanded. They can also conduct physical examinations and inquire about the patient's asbestos exposure history. Certain mesothelioma cases are linked to genetic changes, and therefore certain patients could benefit from genetic tests.
Risk Factors
The main mesothelioma risk factor is exposure to asbestos. Asbestos is a mineral that is made by tiny fibers which are strong and withstand heat. Asbestos is employed in a variety of manufacturing and construction products, including insulation, brakes and shingles. Asbestos dust can be inhaled and swallowed if disturbed. This can cause irritation of the mesothelium over time which may eventually lead to mesothelioma.
People who have had an history of occupational asbestos exposure are at the greatest risk for mesothelioma. This includes people who have worked in industries like mining, shipbuilding and construction and automobile repair. Veterans of the military are also at risk because many branches of the military used asbestos-based material.
A family history of asbestos and radiation therapy to the chest are also factors that increase mesothelioma risk. Additionally the type of mesothelioma that is diagnosed has significant effects on the risk. Pleural mesothelioma, the most prevalent form and typically affects the lungs. Other mesothelioma types include testicular, pericardial and peritoneal.
The risk of mesothelioma generally increases with the third or fourth power of latency, which is the time it takes to identify someone. The incidence of pleural cancer is an increase in incidence after 40 years. Peritoneal and pericardial mesothelioma exhibit the same pattern. Exposure to asbestos that is not occupational, such as living near an asbestos plant or consuming contaminated household products can increase the risk of mesothelioma. In an investigation of six cities, people who were exposed to asbestos in this manner were more likely to develop mesothelioma compared to those who were exposed only to occupational exposure.

Malignant mesothelioma can affect the tissue that surrounds internal organs. Most commonly, it occurs in the lung linings and the abdomen. Mesothelioma can also develop in the lining around the testicles or the heart. It is a rare cancer and the majority of people diagnosed with mesothelioma work on jobs that involved exposure to asbestos. The symptoms of mesothelioma could take years to appear, and the condition is not curable.
Asbestos is one of the minerals with thin microscopically-sized fibers that resist heat, chemicals, and fire. It is widely used in many industries, including shipbuilding manufacturing, construction and many more. Exposure to asbestos may cause mesothelioma because the fibers can get stuck in the tissues of the lining and protecting organs. This causes irritation and damages to cells. This can lead to tumors expanding and eventually becoming cancerous.
The most prevalent mesothelioma form is found in the tissue (pleura) of the lung. It may also begin in the abdomen's lining (peritoneum) or in the membrane surrounding the testicles or the heart. Mesothelioma may also expand to lymph nodes, causing them to expand.
Most people diagnosed with mesothelioma have a history of exposure to asbestos and are also suffering from other ailments like chronic lung disease. The symptoms of mesothelioma are similar to other illnesses, so it is important to see a doctor if you are experiencing warning signs or symptoms. Doctors can inquire about asbestos exposure in the past and perform a physical exam. They may also order scans of your blood and imaging of your abdomen or chest. These tests can reveal any fluid or thickening between the lungs and the chest wall.
Diagnosis
Asbestos fibers that become stuck on the body may cause damage, and eventually develop into cancerous tumours. Different types of asbestos-related cancers develop in various tissues or organs, and each type can be diagnosed with different tests. Mesothelioma can develop in the linings of the chest cavity, lungs, stomach (peritoneum) or around the heart or reproductive organs.
The first step in diagnosing mesothelioma is for a patient to speak with their doctor about their experience with asbestos exposure and the symptoms they've been experiencing. Doctors can also conduct an examination of the body and order tests to determine the health of the lung.
X-rays and CT scans can help doctors gain a better understanding of the affected area. In certain instances doctors will perform the pleural effusion test to determine if mesothelioma, or another disease is causing the accumulation of fluid in the lungs. Pleural effusions could be a sign of pleural, peritoneal or mixed mesothelioma.
Mesothelioma is often misdiagnosed because the symptoms resemble those of other diseases and conditions. The most common symptoms are difficulty breathing and chest pain. Pleural mesothelioma is also a cause of chest tightness, cough and fatigue. Peritoneal mesothelioma may cause abdominal discomfort, swelling and distension. Testicular mesothelioma could manifest as a painful or itchy lump that is located in the testicles.
Researchers are studying certain proteins in the blood in hopes of developing an approach to detect mesothelioma early on. They are also looking into various other tests and procedures that can improve diagnostic accuracy, including mesothelioma imaging as well as MRIs. They are also researching genetic mutations and how to determine if a person is at risk of developing mesothelioma by examining their family history.
Treatment
Asbestos is the main mesothelioma-related risk factor. People who have worked with asbestos, particularly in high-risk occupations such as electrical work, construction or auto repairs, shipbuilding and military service, are at an increased risk.
Exposure to asbestos can cause mesothelioma as fibers become stuck in the tissue that lines and protects vital organs. The fibers cause DNA damage and irritation to the mesothelium which leads to the growth of cancerous cells. Mesothelioma symptoms usually do not appear until decades after exposure.
The symptoms of mesothelioma differ depending on its type and where it is located in the body. The majority of patients with mesothelioma have the lining in their lungs (pleural) however it may also affect the linings of the stomach, the heart and testicles.
Mesothelioma staging helps doctors determine treatment options. The cancer is classified as stage I to stage IV with stages I and II being the earliest and the most treatable. Stage III and IV are the later stages of the cancer and more difficult to treat, however there are many treatment options available.
The most frequent mesothelioma form affects the linings of the lungs and chest wall as well as the abdomen. In most cases of pleural mesothelioma, asbestos exposure occurred in the workplace. Most likely asbestos was inhaled via airborne particles or inhaled through food items.
Other risk factors include a family history of mesothelioma, genetic mutations, and previous radiation therapy for a different condition. If you were exposed to asbestos and are suffering from mesothelioma symptoms it is crucial to see your doctor. You may also benefit from genetic counseling. In certain instances, a mesothelioma specialist can help you file a lawsuit against companies that incorrectly use asbestos in everyday products.
