Mesothelioma Asbestos Lung Cancer

Mesothelioma affects the tissues that line the chest cavity, lungs, and, in some cases, the tissues of the abdomen and the heart. Exposure to asbestos is the main cause of mesothelioma.

Asbestos fibers become stuck in tissues and cause DNA damage. This turns cells into mesothelioma-like cancerous cells.

Signs and symptoms

Mesothelioma is a form of cancer, affects the tissues that line and protect organs within the body. Exposure to asbestos fibers can cause these cells to change and develop into mesothelioma tumors. The majority of mesothelioma cases are found in the lung (pleura). However, it can be found in the abdominal lining as well as the testicles, heart and lungs.

The most frequent mesothelioma-related symptoms are shortness of breath as well as chest pain and coughing. Patients also suffer from abdominal pain, fatigue, and weight loss. These symptoms are similar to those of other ailments and are difficult to identify, particularly in the early stages of mesothelioma. It may take years or even decades after exposure to asbestos for mesothelioma-related symptoms to show up.

The first step to diagnosing mesothelioma is a physical examination and a health history. A doctor might request blood tests and imaging scans to determine the severity of symptoms. These scans may include CT (computer tomography) scans, MRI and PET (positron emission tomography).

X-rays may reveal an unusual swelling or fluid inside the lung. These scans can assist the doctor determine the location of the mesothelioma and the type of mesothelioma. Epithelioid mesothelioma and sarcomatoid are the two main types. Around 70% of mesothelioma cases are epithelioid. Sarcomatoid Mesothelioma has a poorer prognosis and is less prevalent than epithelioid.

The majority of people diagnosed with pleural mesothelioma have a nonproductive cough, chest wall pain, and difficulty breathing. In some cases, a person with pleural mesothelioma could have an abnormal heart murmur, a condition known as pericardial effusion or swelling of the scrotum (tunica vaginalis).

The best way to accurately identify mesothelioma is through the taking of a biopsy of the tissue. The type of mesothelioma determines how a doctor will treat the disease. For example when a patient has mesothelioma pericardial doctors may drain excess fluid with pleurodesis, a procedure that is known as pleurodesis, or insert an indwelling pleural catheter to reduce inflammation and improve breathing. Other options include chemotherapy and surgery.

Diagnosis

Mesothelioma is a cancer that is found in the linings of organs called the mesothelium. The majority of cases occur in the lung (pleura), though it can also develop in the abdomen (peritoneum) or around the testes (tunica vaginalis).

The symptoms of mesothelioma can be noticed between 10 and 50 years after the first exposure. Due to this latency period many patients could be mistakenly diagnosed. The condition is often mistakenly referred to as other, less serious conditions like the flu or pneumonia. This mistake could cause delays in treatment, which could reduce a patient's chance of survival.

Anyone who suspects that they might have mesothelioma must consult their physician immediately. In the initial visit, doctors will review the patient's entire medical history to look for signs and other factors that may make them more susceptible to mesothelioma. This includes any previous exposure to asbestos and asbestos, as well as the nature and duration of the exposure.

The doctor will then order imaging tests of the chest and abdomen to check for signs of mesothelioma. Chest X-rays, CT scans and MRIs all offer detailed images of the interior of the body. They also reveal lung changes, such as pleural thickening or fluid buildup. They can also show whether the mesothelioma tumor has spread to other regions of the body.

A doctor may also recommend an analysis of blood to determine whether the patient has elevated levels of certain substances that are linked to mesothelioma. They may also carry out an operation known as a Thoracentesis which involves removing fluid from the lungs and looking for cancer cells.

If a mesothelioma diagnosis is confirmed, a biopsy will be taken to look at small portions of the tumor to detect cancerous cells. This can be done using VATS (video-assisted surgical thoracoscopic procedure) or by using an instrument that guides the needle through an CT scan. The results of this test will help determine the best mesothelioma treatment for the patient. This could include surgery, chemotherapy or radiation therapy. Some patients might also opt to undergo immunotherapy. This newer form can improve a patient's prognosis and boost their quality of life.

Treatment

Mesothelioma is a type of cancer that is a threat to the tissues that line and protect organs such as the lungs, stomach (peritoneal) or heart or testicles. Although mesothelioma is not curable, it can be treated but treatment can help manage symptoms.

Your doctor will ask about your medical history and search for signs of mesothelioma. Your doctor will also ask about your asbestos exposure, because asbestos attorney 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 the stomach, tummy or the heart (mesothelium). This can cause inflammation over time, and can transform normal cells into cancerous cells. Mesothelioma can be identified using blood tests and imaging tests.

Your healthcare provider will employ a chest X-ray to see changes in the lung tissue and determine if you have fluid build-up (pleural effusion). The doctor will recommend MRI, CT scan or FDG-positron emission tomography (PET) to get detailed images of the affected region. They will also conduct an incision using a needle to collect a sample of the affected tissue.

A mesothelioma expert, also known as a pathologist will look at the mesothelioma tissues under a microscope to identify cancerous cells and determine the type of mesothelioma you have. The pathologist will employ a dye to color the tissue samples in order to determine the type of cancer. The dye will be visible when certain types of mesothelioma are present. They will then employ a special technique to get an in-depth look at the tissue under a microscope.

It can be difficult to determine if you have mesothelioma as the cells that cause it look similar to those of other types of cells in the body. Your medical team will attempt to confirm the diagnosis of mesothelioma with other tests. These tests involve a blood sample to measure the levels of fibulin-3, or mesothelin related peptide that is soluble.

Your healthcare team will decide the best treatment plan for mesothelioma, based on the type of cancer and its stage. The most popular mesothelioma treatments include chemotherapy, surgery, and radiation therapy. If your mesothelioma is in an advanced stage, you may also receive palliative care to ease discomfort and other signs.

Prognosis

The prognosis of mesothelioma is based on the stage and type of cancer as well as factors like age and general health. Patients should consult with skilled doctors to know more about the treatment options available to them.

Mesothelioma develops when asbestos fibers cause damage to the tissues that line and protect vital organs. The asbestos fibers can be breathed in or ingested and, over time, cause inflammation and genetic changes that transform normal cells into mesothelioma-related tumors. The most prevalent forms of mesothelioma are the pleural (which forms on the lung linings as well as the chest cavity and abdomen) mesothelioma.

Doctors diagnose mesothelioma on the basis of symptoms, lab tests and X-rays. They may also recommend that a biopsied to confirm the diagnosis. A biopsy is the removal of a small piece of tissue to be tested. The doctors can compare biopsy samples to an online database to determine the most likely mesothelioma type. This information can be used to estimate the life expectancy of a patient suffering from mesothelioma as well as their treatment plan.

The three mesothelioma types are epithelioid, epithelial and epithelial cells as well as sarcomatoid and biphasic cells. Each mesothelioma type grows at a different rate and responds differently to treatment. Epithelioid mesothelioma makes up 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 be diagnosed following exposure to asbestos, so many patients do not receive a mesothelioma diagnosis until they experience significant symptoms. Asbestos victims should disclose their exposure to a physician and be checked regularly.

During these visits, doctors check for signs of asbestos exposure like scarring on lungs, as well as other respiratory problems. They may also conduct a simple blood test to determine a patient's overall health. If the results indicate that an individual is at a high risk for mesothelioma, they can schedule further tests to get a prognosis. This may include imaging tests like X-rays, CT scans and ultrasound, as well as lung function tests and an chest MRI or PET scan.
