Mesothelioma Asbestos Lung Cancer
Mesothelioma affects the tissues that line the lungs, chest cavity and, in rare instances, the linings of the heart and abdomen. The primary reason for mesothelioma is asbestos exposure.
Asbestos fibers become stuck in tissues and cause DNA damage. Cells turn into cancerous mesothelioma cells.

Mesothelioma is a type of cancer that affects tissues that line and protect organs within the body. Exposure to asbestos fibers could cause these cells to change and develop into mesothelioma tumors. The majority of mesothelioma cases are located in the lung. However, it can be found in the abdominal lining and the testicles, as well as the heart.
Shortness of breath, chest discomfort and coughing are among the most common symptoms of mesothelioma. In addition, some patients experience abdominal pain as well as fatigue, weight loss and abdominal pain. These symptoms can be confusing and difficult to recognize in the beginning stages, especially when mesothelioma is still a relatively young disease. The signs of mesothelioma might not manifest for years or even decades following asbestos exposure.
The first step to diagnose mesothelioma is an examination and a health history. To determine the severity of the symptoms doctors may recommend blood tests and imaging scans. These scans include CT (computer-tomography) scans as well as MRI and PET scans (positron emission Tomography).
X-rays may reveal an unusual lump or a fluid that is present in the lungs. These scans help the doctor determine the kind and location of mesothelioma. Epithelioid mesothelioma and sarcomatoid are the two main types. Epithelioid mesothelioma is responsible for about 70% of mesothelioma cases. Sarcomatoid Mesothelioma has a worse prognosis, and is less frequent than epithelioid.
Most people with pleural cancer have a nonproductive, painful cough and breathing issues. Patients with pleural mesothelioma may have an abnormal heart sound, a condition called pericardial effusion, or swelling of the scrotum.
The most reliable method to determine if mesothelioma has been diagnosed is to collect a tissue sample or biopsy, for testing. The type of mesothelioma also determine how a physician will treat the illness. For example, if a person has mesothelioma of the pericardium the doctor could eliminate excess fluid through pleurodesis, a procedure that is known as pleurodesis, or install an indwelling pleural catheter to reduce inflammation and improve breathing. Other treatments include surgery or chemotherapy.
Diagnosis
The cancerous mesothelioma forms on the organ's linings. The majority of cases occur in the lung (pleura) but it can also develop in the abdomen (peritoneum) or around the testes (tunica vaginalis).
It can take between 10 to 50 years for the first signs of mesothelioma to manifest. Due to this latency period many patients can be mistakenly diagnosed. It is often mistaken for other less serious diseases, such as the flu or pneumonia. This can lead to a delay in treatment that can reduce the chances of survival for a patient.
If you suspect mesothelioma, consult their physician immediately. In the initial appointment, doctors will review the medical history of a patient to determine if there are any symptoms or factors that may increase their risk of mesothelioma. This includes any past exposure to asbestos, and also the type and duration of the exposure.
The next step is for doctors to request imaging tests to look at the abdomen and chest for signs of mesothelioma or other abnormalities. Chest Xrays, CT scans and MRIs all offer detailed images of the inside of the body and can reveal lung changes like the pleural thickening process or the accumulation of fluid. They can also tell if mesothelioma has spread to other parts of the body.
A doctor will also order a blood test to see whether the patient has high levels of certain substances related to mesothelioma. They can also perform an operation known as a Thoracentesis which involves removal of lungs of fluid and examining the lungs for cancerous cells.
If a mesothelioma diagnosis has been confirmed, a biopsy will be performed to examine an insignificant portion of the tumor for cancerous cells. This can be accomplished using VATS (video-assisted surgical thoracoscopic procedure) or by using the use of a needle that is guided by the aid of a CT scan. The results of this test will aid in determining the most effective mesothelioma treatment option for the patient. This could include chemotherapy, surgery, or radiation therapy. Some patients may also choose to participate in immunotherapy. This latest form of treatment can improve a patient's prognosis and boost their quality of life.
Treatment
Mesothelioma, a form of cancer, is a threat to the tissues that line and protect organs such as the stomach, lungs (peritoneal) or heart or testicles. While mesothelioma can't be treated but treatment can help manage symptoms.
Your doctor will ask you about your health history and look for signs of mesothelioma. Your doctor will ask you about asbestos exposure since it is the main risk factor for mesothelioma. Exposure to asbestos can cause asbestos fibers to become trapped in the chest cavity's lining and tummy, or the heart (mesothelium). This causes inflammation over time and can change normal cells into cancerous cells. Mesothelioma can be diagnosed using imaging tests and blood tests.
Your doctor will use a chest X ray to determine if you suffer from fluid accumulation (pleural effusion). Your doctor will recommend an MRI, CT scan, or FDG-positron emissions (PET) to obtain detailed images. They will also conduct an incisional needle biopsy to collect an image of the affected tissue.
A pathologist, a mesothelioma expert, will examine the tissue under an magnifying glass to find cancerous cells and determine their kind. The doctor will use a dye to color the tissues to determine the type of cancer. The dye is visible when certain types of cancer are present. They will then employ a specific method to obtain a closer look at the tissue under the microscope.
It can be difficult to identify mesothelioma since the cells that cause it look similar to those of other types of cells within the body. Your care team will try to confirm the diagnosis with other tests. They may use blood tests to determine levels of fibulin-3 and mesothelin-related peptide that is soluble.
Your healthcare team will decide on a mesothelioma treatment plan depending on the type of cancer you have and how advanced it is. Surgery, chemotherapy and radiotherapy are the most common treatment options for mesothelioma. If your mesothelioma is in advanced stages you could also receive palliative care to relieve discomfort and other signs.
Prognosis
The prognosis for mesothelioma is dependent on the type and stage cancer as well as factors like age and general health. Patients should consult with a doctor who are skilled to find out about their treatment options.
Mesothelioma is a condition that occurs when asbestos fibers harm the tissues that line and protect vital organs. The asbestos fibers are breathed in or eaten, and can cause genetic changes and inflammation that transform normal cells into mesothelioma tumors. The most prevalent forms of mesothelioma are mesothelioma pleural (which forms on the linings of the lungs as well as the chest cavity and abdomen) mesothelioma.
Doctors diagnose mesothelioma using symptoms, laboratory tests and X-rays. They may also recommend an examination to confirm the diagnosis. A biopsy is the removal a small piece of tissue to be examined. The doctors can then compare the biopsy samples against an online database to determine the most likely mesothelioma type. This information can help them determine a patient's mesothelioma life expectancy and treatment plan.
The mesothelioma types are epithelioid, epithelial or epithelial cells, sarcomatoid cells, and biphasic cells. Each mesothelioma type develops at an individual rate and responds to treatment in a different way. Epithelioid mesothelioma makes up 60% to 80% of cases and has a better survival rate than sarcomatoid and biphasic mesothelioma.
It can take as long as 50 years for mesothelioma be diagnosed following exposure to asbestos. Therefore, many patients do not get a diagnosis of mesothelioma until they begin to experience serious symptoms. Asbestos sufferers should report their exposure to a physician and be checked regularly.
During these visits, doctors can examine for signs of exposure to asbestos like scarring on lungs and other respiratory problems. They may also conduct simple blood tests to check the overall health of a patient. If the results show that a patient's risk for mesothelioma is high, they can schedule additional tests to determine mesothelioma-related prognosis. This could include imaging tests like X-rays, CT scans and ultrasound, as well as lung function tests, and an chest MRI or PET scan.
