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. Exposure to asbestos is the primary cause of mesothelioma.

Asbestos fibers get stuck in tissues and cause DNA damage. The result is that cells transform into mesothelioma cancer cells.

Signs and symptoms

Mesothelioma, a form of cancer, affects the tissues which line and protect organs within the body. Exposure to asbestos (cool training) fibers may cause the cells to change and form mesothelioma tumors. Most cases of mesothelioma are located in the lungs. It can also develop in the tissues of the abdomen, the heart and testicles.

Breathlessness, chest discomfort and coughing are among the most common symptoms of mesothelioma. Patients may also feel abdominal pain, fatigue and weight loss. These symptoms are akin to other diseases and are difficult to recognize, especially in the initial stages of mesothelioma. It could take several years or even decades after exposure to asbestos for mesothelioma symptoms to show up.

The first step in identifying mesothelioma is to conduct a physical exam and a medical history. A doctor may ask for blood tests or imaging scans to determine the severity of symptoms. 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 isn't normal in the lungs. These scans can assist the doctor determine the location of the mesothelioma and the type of mesothelioma. The two main mesothelioma types are epithelioid and sarcomatoid. Epithelioid mesothelioma makes up around 70% of mesothelioma cases. Sarcomatoid mesothelioma is less common, and has a worse prognosis than epithelioid mesothelioma.

The majority of people diagnosed with pleural melanoma suffer from a nonproductive cough, chest wall pain and difficulty breathing. Patients with pleural mesothelioma can have an abnormal heart tone, a condition called pericardial effusion or swelling of the scrotum.

The most accurate method to identify mesothelioma is to take an examination of the tissues. The type of mesothelioma that is diagnosed will also determine how a physician treats the illness. If a patient has pericardial cancer, the doctor will remove excess fluid with the procedure called pleurodesis or insert an pleural catheter to decrease inflammation and improve respiration. Other options include chemotherapy and surgery.

Diagnosis

Mesothelioma is a type of cancer that develops in the organ's linings, known as the mesothelium. The majority of cases occur in the lung (pleura), though it can also manifest in the abdomen (peritoneum) or around the testes (tunica vaginalis).

The signs of mesothelioma may be seen between 10 and fifty years after the first exposure. Due to this time of latency, many patients could be mistakenly diagnosed. The condition is often mistakenly referred to as other, less serious illnesses such as the flu or pneumonia. This mistake could result in a delay in treatment that can reduce a patient's chance of survival.

Those who suspect mesothelioma should consult their physician as soon as they can. During the first visit, doctors examine a patient's complete medical history to look for symptoms and any factors that may make them more likely to have mesothelioma. This includes any previous exposure to asbestos litigation and asbestos, and also the type and duration of exposure.

The doctor will then order imaging tests of the chest and abdomen to look for signs of mesothelioma. Chest X-rays CT scans, and MRIs are all able to reveal changes in the lungs, including an increase in pleural thickness or accumulation of fluid. They can also show if the mesothelioma cancer has spread to other regions of the body.

A doctor can also request a test of the blood to determine whether a patient has elevated levels in certain substances linked to mesothelioma. They can also perform a procedure called the thoracentesis. This involves the removal of a sample from the lungs' fluid to check for cancerous cells.

If a mesothelioma diagnosis has been confirmed, a biopsy will be performed to examine a small piece of the tumor to detect cancerous cells. VATS (video assisted thoracoscopic surgical) or a needle-guided CT scan is a method to carry out this procedure. The results of this will aid in determining the best mesothelioma treatment for the patient. This can include surgery, chemotherapy or radiation therapy. Some patients may also choose to participate in immunotherapy. This latest form of treatment can improve the prognosis of patients and improve their quality of life.

Treatment

Mesothelioma affects tissues that line and protect organs, like the lung (pleural mesothelioma), the stomach (peritoneal mesothelioma) or the testicles or heart (pericardial mesothelioma). Although mesothelioma is not curable, it can be treated but treatment can help manage symptoms.

Your doctor will inquire about your health history and check for symptoms of mesothelioma. Your doctor will also inquire about your asbestos claim exposure, as asbestos is the most significant risk factor for mesothelioma. Exposure to asbestos can cause asbestos fibers to get trapped in the lining of the chest cavity and tummy, or the heart (mesothelium). As time passes, this causes inflammation and transforms normal cells into cancerous ones. Mesothelioma can be diagnosed using imaging tests and blood tests.

Your doctor will use chest X-rays to determine if you suffer from fluid accumulation (pleural effusion). Your doctor will recommend an MRI, CT scan, or FDG-positron emissions tomography (PET) to obtain detailed images. They may also perform an incisional needle biopsy to collect an image of the affected tissue.

A pathologist, a mesothelioma specialist, will look at the tissue under a magnifying glass to identify cancerous cell and determine the type. The pathologist will use a dye to color the tissues to identify the cancer. This dye is visible when certain types are present. The doctor will then employ a technique to magnify the tissue.

It can be difficult to identify mesothelioma since the cells that cause it appear similar to those of other types of cells within the body. Your medical team will attempt to confirm the mesothelioma diagnosis with other tests. These tests involve a blood sample to measure the levels of fibulin-3 or soluble mesothelin related peptide.

Your healthcare team will determine mesothelioma treatments based on the type of cancer you suffer from and the degree to which it is advanced. Surgery, chemotherapy and radiotherapy are the most commonly used treatment options for mesothelioma. If your mesothelioma has reached an advanced stages you could also be offered palliative treatment to relieve discomfort and other symptoms.

Prognosis

The outlook for mesothelioma is based on the type and stage of cancer, in addition to other factors such as a patient's age and general health. Patients should consult with doctors who are knowledgeable about their treatment options.

Mesothelioma occurs when asbestos fibers cause damage to the tissues that line and protect vital organs. The asbestos fibers can be inhaled or ingested and, over time, cause inflammation and genetic changes that turn normal cells into mesothelioma tumors. The most prevalent mesothelioma forms are pleural (which forms on the linings of the lungs or chest cavity) and abdomen) mesothelioma.

Doctors diagnose mesothelioma on the basis of symptoms, laboratory tests and X-rays. They may also suggest a biopsy to confirm the diagnosis. A biopsy is the removal a small piece of tissue to be tested. Doctors can then compare biopsy samples to a database to identify the most likely mesothelioma-related cell type. This information can be used to determine the life expectancy of a patient with mesothelioma, as well as their treatment plan.

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

It can take as long as 50 years for mesothelioma develop after exposure to asbestos, which is why many patients don't get a diagnosis of mesothelioma until they begin to experience serious symptoms. asbestos law victims should disclose their exposure to a physician and undergo periodic checkups.

During these visits, doctors will examine for signs of asbestos exposure such as scarring on the lungs and other respiratory problems. They can also do simple blood tests to assess the health of the patient. If the results show that a patient's risk for mesothelioma is very high, they can schedule further tests to determine mesothelioma-related prognosis. This could include imaging tests like X radiations, CT scans, and ultrasounds, as well the lung function test, a chest MRI, or PET scan.
