Mesothelioma

Construction workers, industrial workers, military veterans and others who worked with asbestos-contaminated products are at risk of developing mesothelioma. Exposure to asbestos fibers repeatedly leads to chronic inflammation that damages the mesothelium and causes DNA changes.

Malignant mesothelioma risk increases proportionally with exposure cumulatively and to the third or fourth power of time since first exposure. The symptoms may manifest between 10 and fifty years after exposure.

Signs and symptoms

The mesothelium is a lining of cells that line the body. This lining protects organs and other tissues by lubricating them, allowing they slide against each other without difficulty. Malignant mesothelioma is a cancer that can spread to different areas of the body and affect the lungs, the heart and abdomen. Other symptoms include fatigue and chest pain.

Symptoms of mesothelioma can take 10 to 50 years to manifest, which makes it difficult for doctors to diagnose the disease. It can also be mistaken for other diseases, such as flu or pneumonia.

Patients might experience symptoms like difficulty breathing, persistent coughing and chest pain, or a change in the form of the fingers and nails, called clubbing. Patients with mesothelioma can also develop an accumulation of fluid in the chest (peritoneal) or belly. This is known as an Pleural effusion.

Contrary to lung cancer, mesothelioma can't be detected by imaging tests such as X-rays or CT scans until the cancer has advanced over a period of time. Doctors often need to perform an examination to confirm a mesothelioma diagnose. This can be done using an bronchoscopy, or needle biopsy.

These diagnostic procedures can help doctors make a mesothelioma diagnosis and establish the treatment plan for the patient. Doctors can also review the history of a patient's asbestos exposure to determine whether he or she is at risk of developing asbestos-related illnesses.

The highest risk is for those exposed to asbestos at their work places. Workers in construction, shipbuilding and other blue-collar professions and veterans of the United States Armed Forces are at a high risk. People who live in areas with asbestos-contaminated workers are also at risk of mesothelioma. This is especially the case if the worker has asbestos fibers on their clothing.

People who have been diagnosed with mesothelioma can benefit from regular visits to their family doctor for a checkup and talking about any asbestos-related health concerns. This is crucial because mesothelioma can be mistaken for other illnesses like asbestosis.

Diagnosis

The first signs of mesothelioma often appear like flu, pneumonia or intestinal trouble. The long time of latency means that patients can suffer from symptoms for as long as 10 to 50 years after asbestos exposure. It is also difficult to recognize because of its resemblance to other illnesses. Many mesothelioma symptoms also differ based on the region of the body that is affected.

The first step is to visit a primary care physician or other doctor who can determine the reason for these symptoms. They will ask you for your medical history and check to see if asbestos exposure has been mentioned. They will also perform an examination and conduct basic tests such as blood work or X-rays.

A biopsy might be necessary to confirm a diagnosis, dependent on the type of mesothelioma. A biopsy is performed by inserting a needle in the chest or abdomen and taking a small sample. The tissue is then analyzed to determine whether it is a source of mesothelioma that is cancerous. Mesothelioma cells can be either epithelioid or sarcomatoid, and both types are malignant. Epithelioid mesothelioma accounts for 70% of mesothelioma cases, while sarcomatoid is responsible for the remainder.

After a mesothelioma biopsied has been performed, doctors can develop an action plan. They will refer the patient to an expert who will determine the best treatment option for their particular condition.

Inhalation of asbestos case fibers is the main cause mesothelioma. Asbestos is a class of minerals that appear as bundles of tiny, slender fibers. These fibers are found in rock and soil and are usually released into the air during construction, mining and other activities. Inhaling these fibers can cause inflammation of the lungs. In time, this may cause scarring (asbestosis) and eventually mesothelioma. The majority of cancers are located in the lungs, however it can also grow in the lining of the tummy (peritoneal mesothelioma) or in the testicles (pericardial mesothelioma).

Treatment

Mesothelioma is a type of cancer, that is an abnormal growth of cells that invades nearby tissues and organs. Cancerous cells can also spread to other parts of the body through the bloodstream or lymphatic system.

Mesothelioma treatment options vary depending on the kind and the location of the mesothelioma. Currently, doctors use chemotherapy and surgery to treat mesothelioma. Radiation therapy is often used in combination with surgery and/or chemotherapy. It is used to reduce the pain and swelling caused by mesothelioma and kill cancerous cells.

Asbestos exposure could cause asbestosis. This is a non-cancerous illness that causes scarring in the lungs and on other parts of the human body. Asbestos exposure may also trigger mesothelioma which is a more severe form of asbestos litigation legal (read here) disease that can be fatal. Mesothelioma, an aggressive cancer, usually affects the lungs and abdomen. Symptoms include breathing problems, chest pain, and coughing. X-rays or CT scans can diagnose mesothelioma. The images that result show areas with increased density, which could indicate either scar tissue (or an actual tumor). Doctors may perform a needle biopsy or bronchoscopy to determine the difference.

A bronchoscopy is done by inserting an extremely thin flexible tube into the respiratory passages to visualize the tissue and then collect samples to test. A needle biopsy involves injecting liquid into the area to remove a small amount of tissue to test. Both procedures are painful, but the results can help doctors identify mesothelioma and asbestosis.

The symptoms of mesothelioma are similar to those of other illnesses and can manifest as long as 50 years after initial exposure. It can be difficult to diagnose mesothelioma due to the latency period that occurs between asbestos exposure and symptoms. It is common for people to be misdiagnosed with other illnesses like pneumonia or the flu.

Although scientists aren't able to pinpoint for sure what causes mesothelioma, they do know that exposure to asbestos increases the risk. Asbestos exposure could be caused by working in industries like asbestos mining, manufacturing, and construction. Workers also transport asbestos-containing substances to their homes as well as other work places, where they could inhale or swallow the fibers. The asbestos types most frequently involved in mesothelioma cases are serpentine and amphibole asbestos fibers. The serpentine type is generally less carcinogenic than amphibole types but both types may cause disease.

Prognosis

Mesothelioma is a rare type of cancer that affects the thin layer of tissue that line internal organs. It usually develops due to exposure to asbestos, which is a group of minerals that are strong and resistant to heat. It is believed asbestos lawsuit fibers enter the lungs and irritate the mesothelium. This irritation can cause genetic mutations that eventually result in the growth of tumours.

Asbestos can be exposed in many ways, like during mining, manufacturing cleaning or repairing asbestos products. It is also possible to be exposed during the daily routine of a person's life, such as washing or wearing clothing that contains asbestos. Some people are more at risk of developing mesothelioma because of their family history of the illness, or they have an increased risk due to other factors, such as genetics.

People with mesothelioma can have a variety of symptoms that often mimic other illnesses. It is often difficult for doctors to diagnose mesothelioma at its early stages. It is important for people who have been exposed to asbestos to share their medical history to their doctor and request regular check-ups.

The majority of mesothelioma cases are caused by occupational asbestos exposure. However, studies show that exposure to asbestos from the environment can cause mesothelioma too. This is because asbestos dust can travel from the workplace to other places in the area where people live. Mesothelioma is more frequent for those who live within 2000 metres of an asbestos lawsuit mine or cement plant.

Some patients with mesothelioma are diagnosed with asbestosis, a lung disease, before their mesothelioma starts. Asbestosis can cause the lungs to become thicker and make it difficult for patients to breathe. People suffering from this condition are likely to need to use oxygen at home, and may have to undergo lung procedures like the lobectomy.

Additionally, a few people suffering from mesothelioma may be treated for symptoms of their cancer. Some people with mesothelioma are treated with drugs to improve their breathing or be part of clinical studies to test treatments. Mesothelioma is still a deadly cancer, but early detection and treatment can improve the prognosis. Patients who have undergone multiple cycles of chemotherapy and surgery have been able extend their lives by up to 10 years.
