Mesothelioma
Construction workers, industrial workers, military veterans and others who worked with asbestos-contaminated products are at risk of developing mesothelioma. The repeated exposure to asbestos fibers creates chronic inflammation that damages the mesothelium, causing DNA changes.
The risk of malignant mesothelioma increases proportionally to cumulative exposure, and to the third or fourth power since first exposure. It could take between 10 and 50 years after exposure for symptoms to appear.
Signs and symptoms
Mesothelioma is a type of cancer that is found in the cells that line body areas, known as the mesothelium. This lining protects the organs and tissues by lubricating it so that it can slide effortlessly against each other. Malignant mesothelioma can grow to other parts of the body, and affect the heart, lungs and abdomen. Other symptoms include chest pain and fatigue.
Mesothelioma symptoms can take anywhere from 10 to 50 years before they show up, which makes it difficult for doctors to recognize the disease. It is also possible to confuse with other conditions such as the flu or pneumonia.
Patients might experience symptoms like difficulty breathing, persistent coughing, chest pain or a change in the shape of the fingers and nails which is known as clubbing. Patients with mesothelioma might also experience a fluid accumulation in the chest (peritoneal) or belly. This condition is known as a pleural effusion.
As with lung cancer, mesothelioma isn't visible on imaging tests, like an X-ray or CT scan until the cancer has grown for a number of years. Doctors often need to perform an examination to confirm a mesothelioma diagnosis. This can be accomplished with the use of a bronchoscopy or needle biopsy.
These tests can help doctors determine if mesothelioma is a cause and develop the best treatment option for the patient. Doctors can also review the history of a patient's asbestos exposure to determine whether he or she is at risk for developing asbestos-related diseases.
People exposed to asbestos in their workplaces are at risk of developing mesothelioma and other illnesses. The most at-risk occupations are those employed in shipbuilding, construction and other blue-collar fields, as well as veterans of the United States Armed Forces. People who are exposed to asbestos workers are also at risk of mesothelioma, particularly if the worker brings asbestos fibers home on his or her clothing.
People who have been diagnosed with mesothelioma can benefit from regular visits to their family doctor to have a check-up and talk about any health concerns related to asbestos. This is particularly important since mesothelioma can be mistaken for other diseases, such as asbestosis.
Diagnosis
The early signs of mesothelioma may look like flu, pneumonia or intestinal problems. The long latency period of the disease means patients may experience symptoms for 10 - 50 years after asbestos exposure. It is also difficult to diagnose due to its similarity to other illnesses. The symptoms of mesothelioma differ based on the region of the body affected.
The first step is to talk with an primary care doctor or a different doctor who can determine the cause of your symptoms. They will ask for an entire medical history and determine if exposure to asbestos has been mentioned. They will also conduct an examination and run basic tests like blood tests or X-rays.
Based on the type of mesothelioma, a biopsy may be needed to confirm the diagnosis. A biopsy is performed by inserting a needle in the chest or abdomen and taking a small sample. The tissue is then examined to determine whether it is a source of cancerous mesothelioma. Mesothelioma cells are either epithelioid or sarcomatoid, and both are malignant. Epithelioid mesothelioma accounts for 70 percent of mesothelioma patients, while sarcomatoid mesothelioma accounts for the rest.
After a mesothelioma biopsied has been done, doctors can create an action plan. They will usually refer the patient to a specialist in order to determine the best treatment option for their condition.
Mesothelioma is caused by the inhalation of tiny asbestos fibers. Asbestos is minerals that appear like a clump of tiny fibers. They are found in soil, rock and are released into the atmosphere during mining and construction. When inhaled, these fibers become stuck in the lung and cause inflammation. This can eventually result in mesothelioma. The cancer is usually located within the lungs, but it can also form in the lining of the stomach (peritoneal mesothelioma) or in the testicles (pericardial mesothelioma).
Treatment
Mesothelioma also referred to as cancer is an abnormal growth of cells that invades tissues and organs in the vicinity. Cancerous cells may also spread to other areas of the body through the lymphatic system or bloodstream.
Mesothelioma treatment options differ based on the type and location of mesothelioma. Currently, doctors use chemotherapy and surgery to treat mesothelioma. The use of radiation therapy is typically in conjunction with chemotherapy and/or surgery. It is used to lessen the pain and swelling caused by mesothelioma and kill cancerous cells.
Asbestos exposure may cause asbestosis. This is a non-cancerous illness that causes scarring to the lungs as well as on other organs of the body. It can also cause mesothelioma, a more serious type of asbestos disease that's typically fatal. Mesothelioma is a cancer that is aggressive is most often found in the lungs and abdomen. Symptoms can include breathing problems, coughing and chest pain. X-rays or CT scans can detect mesothelioma. The results of CT scans reveal areas with higher density, which could indicate scar tissue or a tumor mass. Doctors can perform an bronchoscopy or needle biopsy to determine the distinction.
A bronchoscopy is performed by inserting a thin flexible tube into respiratory passages to observe the tissue and take samples for testing. A needle biopsy involves injecting liquid into the area to remove some tissue for testing. Both procedures are painful, however they aid in diagnosing mesothelioma or asbestosis.
The symptoms of mesothelioma are similar to those of other illnesses and can manifest up to 50 years after the initial exposure. The latency period between asbestos exposure and the onset of symptoms can make it difficult to diagnose the condition. Many people are misdiagnosed as having other diseases, such as pneumonia or flu.
While scientists don't know for certain what causes mesothelioma they do understand that exposure to asbestos can increase the risk. Asbestos exposure could be caused by working in industries like asbestos mining, manufacturing, and construction. As well, asbestos-containing products are often carried by workers to their homes and other workplaces where the fibres can be ingested or inhaled. Amphibole and snakeine asbestos fibres are the most prevalent kinds of asbestos found in mesothelioma. The type of asbestos known as serpentine is less harmful than amphibole one, however both are capable of causing illness.
Prognosis
Mesothelioma, a rare form of cancer, affects the thin layer that lines internal organs. It is typically caused by exposure to asbestos, a grouping of minerals that are resistant to heat and strong. It is believed that asbestos fibres enter the lungs, irritate the membranes, and eventually cause cancer. Over time the irritation could cause genetic mutations that result in the growth of tumours.
Asbestos can be uncovered in a variety of ways, including when mining, manufacturing cleaning or repairing asbestos products. It is also possible to be exposed at home through washing or putting on asbestos-containing clothes. Certain people are at a higher risk of developing mesothelioma because of their genetic or family history predisposition.
Mesothelioma patients may exhibit many symptoms that are usually similar to other diseases. It is often difficult for doctors to recognize mesothelioma in its early stages. It is important for people who have been exposed to asbestos to discuss their medical history to their physician and request regular checks.
The majority of cases of mesothelioma result from asbestos exposure at work. Studies have proven that exposure to asbestos may cause mesothelioma. This is because asbestos dust can move from work sites to other areas in which people reside. Residents who live within 2000m of an asbestos mine or cement plant are at greater risk of mesothelioma.
Before developing mesothelioma, some people develop asbestosis. Asbestosis can cause thickening of the lung, which can make it difficult to breathe. Patients with this condition are likely to require oxygen at home, and may require lung surgery like the lobectomy.
Certain mesothelioma patients also receive treatment for their symptoms. Certain mesothelioma patients are given drugs to help breathe or take part in clinical studies for treatments that are experimental. Mesothelioma is still a fatal disease, but early diagnosis and treatment can improve the prognosis. Davenport asbestos lawyers who have undergone multiple rounds of surgery and chemotherapy have been able to extend their lives by up to 10 years.
