Mesothelioma Asbestos Lung Cancer
Mesothelioma affects the tissue that lines the lungs, chest cavity and, in rare instances, the tissues of the abdomen and heart. Exposure to asbestos is the principal reason for mesothelioma.
Asbestos fibers may get stuck in tissues, causing DNA damage. This causes cells to transform into mesothelioma cancer cells.
Symptoms
Mesothelioma is a type of cancer that affects the tissues that line and protect organs within the body. Exposure to asbestos fibers can cause cancerous cells to transform into mesothelioma-related tumors. The majority of cases of mesothelioma originate in the lungs (pleura). However, it can occur in the lining of the abdomen and the testicles, as well as the heart.
Chest discomfort, and coughing are the most frequent symptoms of mesothelioma. Patients may also suffer from abdominal pain, fatigue and weight loss. These symptoms are similar to many other diseases and are difficult to recognize, especially in the initial stages of mesothelioma. The signs of mesothelioma might not be evident for a long time or even decades after asbestos exposure.
The first step in identifying mesothelioma is an examination and a medical history. To determine the severity of the symptoms the doctor can order tests for blood and imaging scans. These scans include CT (computer-tomography) scans as well as MRI and PET scans (positron emission Tomography).
X-rays can reveal a mass or fluid that is not normal in the lungs. These scans may help the doctor determine the location of the mesothelioma and the type of mesothelioma. The two most common mesothelioma types are sarcomatoid and epithelioid. About 70% of mesothelioma is epithelioid. Sarcomatoid Mesothelioma has a worse prognosis and is less prevalent than epithelioid.
Most people with pleural cancer have a nonproductive, painful cough and breathing problems. In some cases, people with pleural mesothelioma could have an abnormal heart murmur, which is called pericardial effusion, or swelling of the scrotum (tunica vaginalis).
The most accurate method to identify mesothelioma is through a biopsy of tissue. The type of mesothelioma also determines the way a doctor treats the disease. If a patient has pericardial cancer the doctor will remove excess fluid with a procedure known as pleurodesis, or insert an pleural catheter to reduce inflammation and enhance respiration. Other treatments include surgery and chemotherapy.
Diagnosis
The mesothelioma cancerous form is found in the linings of the organs. The majority of the time, the disease develops in the lungs (pleura) however it can also develop in the abdomen (peritoneum) or around the testes (tunica vaginalis).
The symptoms of mesothelioma could appear between 10 and fifty years after the initial exposure. Because of this latency period, many patients may be misdiagnosed. It is often misinterpreted as other, less serious illnesses, such as the flu or pneumonia. This mistake could result in delays in treatment, which could reduce the chances of survival.
Those who suspect that they might have mesothelioma should consult their physician immediately. During the initial visit, doctors will take a patient's full medical history to determine signs and other factors that might make them more likely to have mesothelioma. This includes previous asbestos exposure, as well the nature and duration of the exposure.
The next step is for doctors to conduct imaging tests to examine the abdomen and chest for signs of mesothelioma and other abnormalities. Chest Xrays, CT scans and MRIs all provide detailed images of the inside of the body and can show lung issues like pleural thickening or fluid buildup. They can also tell whether mesothelioma has spread other parts of the body.
A doctor may also recommend an analysis of blood to determine if the patient has high levels of certain substances that are related to mesothelioma. They may also carry out an operation called a thoracentesis which involves removing fluid from the lungs and examining for cancerous cells.
If mesothelioma is found to be the cause, a biopsy is performed to examine a small portion of the tumor for cancerous cells. This can be done using VATS (video-assisted surgery using thoracoscopic instruments) or by using a needle guided by a CT scan. The results will aid in determining the best mesothelioma treatment for the patient. This may include chemotherapy, surgery or radiation therapy. Certain patients may also choose to undergo immunotherapy. This newer form of mesothelioma treatment may improve the quality of life for patients and improve their outlook.
Treatment
Mesothelioma affects the tissues that line and protect organs, like the lung (pleural mesothelioma) and stomach (peritoneal mesothelioma) or the heart or testicles (pericardial mesothelioma). It is not possible to cure mesothelioma but treatment can help reduce symptoms.
Your doctor will ask about your medical history and search for signs of mesothelioma. Your doctor will also inquire about your exposure to asbestos, because asbestos is the most significant risk factor for mesothelioma. Exposure to asbestos can cause asbestos fibers to get trapped in the tissues of the chest cavity, tummy or heart (mesothelium). This can cause inflammation over time and can transform normal cells into cancerous cells. Mesothelioma can be identified using imaging tests and blood tests.
Your healthcare provider will employ a chest X-ray to see changes in your lung tissue, and determine if you suffer from an accumulation of fluid (pleural effusion). mesothelioma asbestos claim will request an MRI, CT scan, or FDG-positron emissions (PET) to obtain high-quality images. They will also perform an incision using a needle to collect a sample from the affected tissue.
A mesothelioma expert, also known as a pathologist will examine the mesothelioma tissues under a microscope to identify cancerous cells and determine what type of mesothelioma that you have. To make the diagnosis, the pathologist will stain the sample with a dye that lights up when certain types of proteins are present. They will then use a special technique to get a closer look at the tissue under the microscope.
Mesothelioma is often difficult to identify because the mesothelioma cells look like other types of cells within the body. Your care team will try to confirm the mesothelioma diagnosis by performing other tests. These tests involve the collection of blood samples to determine the levels of fibulin-3 or soluble mesothelin related peptide.
Your care team will decide on mesothelioma treatments based on the type of cancer you have and the degree to which it is advanced. Radiotherapy, chemotherapy and surgery are the most common treatments for mesothelioma. If your mesothelioma is in an advanced stage you could also receive palliative care to relieve discomfort and other signs.
Prognosis
The prognosis for mesothelioma patients is dependent on the type and stage of cancer as well as factors like age and general health. Patients should consult with experienced doctors to learn more about the treatment options available to them.
Asbestos fibers can cause damage to tissues that line vital organs and protect them from harm. The asbestos fibers are breathed in or consumed, and they can cause genetic changes and inflammation that transform normal cells into mesothelioma tumors. The most frequent mesothelioma variants are pleural mesothelioma, which is a form of cancer that develops in the lining of the lungs and the chest cavity (pleura) and mesothelioma of the peritoneal region, a rarer form that arises in the lining that protects the abdomen.
Doctors diagnose mesothelioma on the basis of symptoms, laboratory tests, and X-rays. They may also suggest taking a biopsy to confirm the diagnosis. A biopsy is when you take a small sample of tissue to test. The doctors can compare the biopsy samples with databases to determine the most likely type of mesothelioma cells. This information will help them predict the patient's mesothelioma's life expectancy and treatment plan.
Mesothelioma cells can be classified into three categories: epithelioid, epithelial, biphasic and sarcomatoid. Each mesothelioma forms at a different pace and responds differently to treatment. Epithelioid mesothelioma is responsible for 60% to 80% of cases and has a higher survival rate than sarcomatoid or biphasic mesothelioma.
It can take up to 50 years for mesothelioma develop after exposure to asbestos, so many patients do not be diagnosed with mesothelioma until they experience significant symptoms. Asbestos exposure must be reported to a doctor, and victims should be checked regularly.
During these visits, doctors check for signs of asbestos exposure such as scarring on the lung and other respiratory issues. They can also conduct an easy blood test to determine the health of the patient. If the results indicate that a patient's risk for mesothelioma is high they can schedule additional tests to get mesothelioma-related prognosis. This will include imaging tests such as X-rays, CT scans and ultrasound as well as lung function tests, and an chest MRI or PET scan.
