Mesothelioma Asbestos Lung Cancer
Mesothelioma is a cancer that affects the tissue that lines the lungs and chest cavity and, in rare instances the abdomen's lining and the heart. The main reason for mesothelioma is asbestos exposure.
Asbestos fibers are entangled in tissues and cause DNA damage. This changes cells into mesothelioma cancer cells.
Symptoms
Mesothelioma is a type of cancer that affects the tissues that line and protect organs in the body. Exposure to asbestos fibers can cause these cells to change and develop into mesothelioma tumors. The majority of mesothelioma cases originate in the lungs (pleura). However, it can also happen in the abdominal lining, heart and testicles.
Shortness of breath, chest discomfort, and coughing are the most common symptoms of mesothelioma. In addition, some patients are suffering from abdominal pain, weight loss, and fatigue. These symptoms are akin to other ailments and are difficult to diagnose, especially in the early stages of mesothelioma. The signs of mesothelioma might not manifest for years or even decades following asbestos exposure.
A physical exam and a patient's health history are the first step to diagnose mesothelioma. To determine the severity of the symptoms, a doctor may order imaging tests and blood tests. These scans include CT (computer-tomography) scans as well as MRI and PET scans (positron emission Tomography).
X-rays may reveal a mass or fluid that isn't normal in the lung. These scans can help the doctor determine the location of the mesothelioma and the type of mesothelioma. The two most common types of mesothelioma are sarcomatoid and epithelioid. Around 70% of mesothelioma is epithelioid. Sarcomatoid mesothelioma is less common and has a poorer prognosis than epithelioid mesothelioma.
Most people with pleural cancer suffer from a painful, non-productive cough and breathing difficulties. A person with pleural msothelioma can suffer from an abnormal heart sound and a condition known as pericardial effusion or swelling of the scrotum.
The most accurate method to identify mesothelioma is to take a biopsy of tissue. The type of mesothelioma determines how a doctor will treat the illness. For instance in the case of mesothelioma pericardial the doctor could drain excess fluid with a procedure called pleurodesis or install an indwelling pleural catheter to decrease inflammation and improve breathing. Other treatments include surgery and chemotherapy.
Diagnosis
The mesothelioma cancerous form is found in the organ's linings. The majority of cases occur in the lungs, however it can also manifest in the abdomen (peritoneum) or around the testes.
It can take between 10 to 50 years for the symptoms of mesothelioma to appear. Because of this time period of latency it is possible for patients to be incorrectly diagnosed. It is often mistaken for other less serious illnesses, such as pneumonia or the flu. This mistake could result in delays in treatment, which could lower a patient's chances of survival.
Anyone who suspects that they might have mesothelioma should see their doctor immediately. In the initial visit, doctors take a patient's full medical history to look for signs and any other factors that could make them more likely to have mesothelioma. This includes previous asbestos exposure, as well the nature and duration of the exposure.
The doctor will then recommend imaging tests of the abdomen and chest to determine if there are signs of mesothelioma. Chest X-rays, CT scans, and MRIs can all show changes in the lungs, like an increase in pleural thickness or accumulation of fluid. They can also reveal whether mesothelioma has spread other areas of the body.
A doctor will also order an analysis of blood to determine whether the patient has elevated levels of certain substances that are associated with mesothelioma. They can also perform an operation called a thoracentesis which involves removing fluid from the lungs and looking for cancer cells.
If a mesothelioma diagnosis is confirmed the biopsy procedure is carried out to examine a small portion of the tumor for cancerous cells. This can be accomplished using VATS (video-assisted surgical thoracoscopic procedure) or through an instrument that guides the needle through a CT scan. The results will aid in determining the best mesothelioma treatment option for the patient. This could include chemotherapy, surgery, or radiation therapy. Some patients might also opt to take part in immunotherapy. This newer type of treatment can enhance the prognosis of patients and improve their quality of life.
Treatment
Mesothelioma affects the tissues that line and protect organs, including the lung (pleural mesothelioma), the stomach (peritoneal mesothelioma) or the testicles or heart (pericardial mesothelioma). It is not possible to cure mesothelioma, but treatment may help control symptoms.
Your doctor will ask about your medical history and look for signs of mesothelioma. Your doctor will also ask about your asbestos exposure since this is the number one risk factor for mesothelioma. Exposure to asbestos can cause asbestos fibers to become trapped in the lining of the chest cavity, tummy or heart (mesothelium). As time passes this causes inflammation and transforms normal cells into cancerous ones. Mesothelioma is diagnosed with blood tests and imaging tests.
Your doctor uses chest X-rays to determine if there is fluid accumulation (pleural effusion). Your provider will order MRI, CT scan or FDG-positron emission tomography (PET) to obtain precise images of the affected area. They will also perform an incision using a needle to collect a sample from the affected tissue.
A pathologist, or mesothelioma specialist, will look at the tissue under a magnifying lens to detect cancerous cell and determine the type. The doctor will use a dye to stain the tissues to identify the cancer. This dye is visible when certain types are present. The doctor will then employ an instrument to magnify the tissue.
It can be difficult to diagnose mesothelioma because the cells that cause it appear similar to those of other types of cells within the body. Your healthcare team will confirm the diagnosis of mesothelioma using other tests. This includes a blood test to measure levels of fibulin-3 and soluble mesothelin-related peptide.
Your healthcare team will decide the best treatment plan for mesothelioma based on the type of cancer you have and its stage. The most commonly used mesothelioma treatment options include chemotherapy, surgery and radiation therapy. If your mesothelioma is in advanced stages you could also be offered palliative care to relieve discomfort and other symptoms.
Prognosis
The prognosis for mesothelioma depends on the type and the stage of cancer, and other factors such as a patient's age and general health. Patients should consult with doctors who are knowledgeable about their treatment options.
Asbestos fibers may damage the tissues that line vital organs and safeguard them. These asbestos fibers can be inhaled or consumed and, over time, cause inflammation and genetic changes that turn normal cells into mesothelioma tumors. The most prevalent mesothelioma types are pleural mesothelioma. It occurs in the lung lining and the chest cavity (pleura), as well as peritoneal mesothelioma, a rarer type that is found in the lining of the abdomen.
Doctors diagnose mesothelioma using symptoms, laboratory tests, and X-rays. They may also recommend that a biopsied to confirm the diagnosis. A biopsy is the process of taking tiny amounts of tissue to test. The doctors can compare the biopsy samples with a database in order to determine the most likely mesothelioma type. This information can be used to estimate the life expectancy of a person suffering from mesothelioma as well as their treatment plan.
The mesothelioma types are epithelioid and epithelial, epithelial cells as well as sarcomatoid and biphasic cells. Each mesothelioma grows at a different pace and responds differently to treatment. Epithelioid mesothelioma makes up 60 percent to 80% of cases and has a higher survival rate than sarcomatoid or biphasic mesothelioma.
It can take as long as 50 years for mesothelioma develop following exposure to asbestos, so many patients do not receive a mesothelioma diagnosis until they begin to experience serious symptoms. Asbestos sufferers should report their exposure to a physician and be checked regularly.
In these visits, doctors will look for signs of exposure to asbestos, such as scarring around the lungs, or other respiratory issues. boston asbestos attorney can also perform a simple blood check to determine the patient's health. If the results indicate that the patient is at a the highest risk of developing mesothelioma they can schedule additional tests to get an estimate of the prognosis. This will include imaging tests like X-rays, CT scans and ultrasound, as well as a lung function test and a chest MRI or PET scan.
