Mesothelioma Asbestos Lung Cancer

Mesothelioma is a form of cancer that affects the tissue that lines the lungs and chest cavity and, in some cases the abdomen's lining and the heart. Exposure to asbestos is the principal cause of mesothelioma.

Asbestos fibers are entangled in tissues and cause DNA damage. This causes cells to transform into mesothelioma cancer cells.

Symptoms

Mesothelioma is a form of cancer, affects the tissues that connect and protect organs in the body. Exposure to asbestos fibers may cause the cells to change and form mesothelioma tumors. The majority of cases of mesothelioma are found in the lungs (pleura). It can also be found in the linings of the abdomen, the heart and testicles.

The most frequent mesothelioma-related symptoms are breathlessness, chest pain and coughing. In addition certain patients experience abdominal pain, weight loss, and fatigue. These symptoms are similar to many other illnesses and can be difficult to diagnose, especially in the early stages of mesothelioma. It may take years or even decades following exposure to asbestos settlement for mesothelioma-related symptoms to manifest.

A physical exam and a health history of the patient are the first step in diagnosing mesothelioma. To determine the severity of symptoms, a doctor may 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 could reveal a lump or fluid that is not normal in the lung. These scans aid the doctor determine the nature and location of the mesothelioma. The two main types of mesothelioma are sarcomatoid and epithelioid. Epithelioid mesothelioma makes up around 70% of mesothelioma cases. Sarcomatoid mesothelioma is a lesser-known type and has a less favorable prognosis than epithelioid mesothelioma.

Most patients diagnosed with pleural mesothelioma suffer from a nonproductive cough, chest wall pain and difficulty breathing. In some instances, a patient with pleural mesothelioma could have an abnormal heart murmur a condition called pericardial effusion, or swelling of the scrotum (tunica vaginalis).

The best way to accurately diagnose mesothelioma involves the taking of a biopsy of the tissue. The type of mesothelioma that is diagnosed will also determine how a physician will treat the illness. For example, if a person has pericardial mesothelioma doctors may drain excess fluid with pleurodesis procedure or insert a pleural catheter in the body to reduce inflammation and improve breathing. Other treatments include surgery and chemotherapy.

Diagnosis

Mesothelioma is a cancer that is found in the organ's linings, known as the mesothelium. The disease most commonly occurs in the lung (pleura) but it can also develop in the abdomen (peritoneum) or around the testes (tunica vaginalis).

It takes between 10 to 50 years for the symptoms of mesothelioma to manifest. Due to this latency period it is possible for patients to be incorrectly diagnosed. This illness is often misdiagnosed as other, less serious illnesses such as pneumonia or the flu. This misdiagnosis can lead to delays in treatment, which may decrease the chance of surviving.

Those who suspect mesothelioma should visit their doctor as soon as possible. At the first visit, doctors review the medical history of the patient to determine if there are any symptoms or conditions that could increase the likelihood of developing mesothelioma. This includes any prior exposure to asbestos legal and asbestos, and also the type and duration of exposure.

The next step is for doctors to request imaging tests to look at the chest and abdomen for signs of mesothelioma or other abnormalities. Chest Xrays, CT scans and MRIs all provide precise images of the inside of the body. They also reveal lung changes, such as the thickening of the pleura or the buildup of fluid. They can also tell whether mesothelioma cancer has spread to other areas of the body.

A doctor may also order an examination of the blood to determine whether a patient has elevated levels of certain substances that are linked to mesothelioma. They can also perform an operation known as a thoracentesis. It involves the removal of a small amount of the lungs' fluid to search for cancerous cells.

If a mesothelioma diagnosis has been confirmed the biopsy procedure will be taken to check an insignificant portion of the tumor to detect cancerous cells. This can be accomplished using VATS (video-assisted thoracoscopic surgery) or with the use of a needle that is guided by the aid of a CT scan. The results will aid in determining which mesothelioma treatment options are most suitable for the patient. This can include chemotherapy, surgery, or radiation therapy. Some patients also choose to undergo immunotherapy. This newer form of mesothelioma treatment may improve a patient's quality of life and improve their outlook.

Treatment

Mesothelioma affects tissues that line and protect organs, including the lungs (pleural mesothelioma) as well as the stomach (peritoneal mesothelioma) or the testicles or heart (pericardial mesothelioma). It is not possible to treat mesothelioma completely, however treatment can help manage symptoms.

Your doctor will inquire about your medical history and search for symptoms of mesothelioma. Your doctor will also ask about your asbestos exposure, as asbestos lawsuit 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 change normal cells into cancerous cells. Mesothelioma is diagnosed with blood tests and imaging tests.

Your doctor will use an X-ray of the chest to determine if there is an accumulation of fluid (pleural effusion). Your healthcare provider will request an MRI, CT scan, or FDG-positron emissions (PET), to get detailed images. They may also perform an incisional needle biopsy to collect an in-situ sample of the affected tissue.

A mesothelioma specialist called a pathologist will look at mesothelioma cells under a microscope in order to find cancerous cells and determine the type of mesothelioma you have. The pathologist will use a dye to stain the tissue samples in order to identify the cancer. The dye will be visible when certain types of cancer are present. The doctor will then use techniques to magnify the tissue.

Mesothelioma is often difficult to recognize because mesothelioma cells appear like other types of cells in the body. Your healthcare provider will confirm the diagnosis of mesothelioma by other tests. These include a blood test to measure levels of fibulin-3 and mesothelin-related peptide that is soluble.

Your healthcare team will determine the best treatment option for mesothelioma, based on the type of cancer you have and its stage. The most popular mesothelioma treatments include chemotherapy, surgery and radiation therapy. A palliative treatment option is available in the event that your mesothelioma has progressed to an advanced stage. This will alleviate you of pain and other signs.

Prognosis

The prognosis for mesothelioma patients is dependent on the type and stage cancer as well as factors such as age and general health. Patients should consult with experienced doctors to learn more about their treatment options.

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

Doctors diagnose mesothelioma using symptoms, laboratory tests and X-rays. They may also suggest taking a biopsy to confirm the diagnosis. A biopsy involves taking a small sample of tissue to test. The doctors can then compare the biopsy samples with an online database to determine the most likely type of mesothelioma cells. This information can help them determine the mesothelioma-related life expectancy of a patient and treatment plan.

The mesothelioma types are epithelioid, epithelial and epithelial cells, sarcomatoid cells and biphasic cells. Each mesothelioma grows at a different rate and responds differently to treatment. Epithelioid cancer is responsible for 60 to 80 percent of all cases, and has a better survival rate than biphasic mesothelioma or sarcomatoid.

It can take up to 50 years for mesothelioma to develop after exposure to asbestos. Therefore, many patients do not be diagnosed with mesothelioma until they show signs of. Asbestos victims should disclose their exposure to a doctor and undergo periodic checkups.

During these visits, doctors will look for signs of asbestos exposure such as scarring on the lungs and other respiratory problems. They can also conduct an easy blood test to determine the health of the patient. If the results show that a patient's risk of developing mesothelioma is very high, they can arrange for further tests to receive a mesothelioma prognosis. This will include imaging tests like X-rays, CT scans and ultrasound, as well as a lung function test and an chest MRI or PET scan.
