Mesothelioma Asbestos Lung Cancer

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

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

Symptoms

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

The most common mesothelioma symptoms include shortness of breath as well as chest pain and coughing. Patients may also experience abdominal pain, fatigue, and weight loss. These symptoms are similar to many other diseases and are difficult to recognize, especially in the beginning stages of mesothelioma. The signs of mesothelioma might not manifest for years or even decades after asbestos exposure.

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

X-rays can reveal a strange lump or a fluid that is present in the lung. These scans can help the doctor determine where the mesothelioma is and the kind of mesothelioma. The two main mesothelioma types are sarcomatoid and epithelioid. Epithelioid mesothelioma accounts for around 70% of all mesothelioma cases. Sarcomatoid mesothelioma is a lesser-known type, and has a worse prognosis than epithelioid mesothelioma.

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

The most reliable method to identify mesothelioma is take a tissue sample or biopsy, to test. The type of mesothelioma also determines the way a doctor treats the disease. For example when a patient has pericardial mesothelioma doctors may eliminate excess fluid through pleurodesis procedure or insert a pleural catheter in the body to reduce inflammation and improve breathing. Other treatments include chemotherapy and surgery.

Diagnosis

The mesothelioma cancerous form is found in the linings of the organs. The disease is most prevalent in the lungs, but it can also be found in the abdomen (peritoneum), or around the testes.

It takes between 10 and 50 years for symptoms of mesothelioma or mesothelioma onset. Due to this latency period many patients could be incorrectly diagnosed. This condition is often mistakenly referred to as other, less serious conditions such as the flu or pneumonia. This mistake could result in delays in treatment, which may decrease the chance of surviving.

Anyone who suspects that they may have mesothelioma need to consult their physician immediately. During the initial visit, doctors will examine a patient's complete medical history to identify symptoms and any factors that might make them more likely to have mesothelioma. This includes past asbestos exposure and the kind and duration.

The next step is for doctors to request imaging tests to look at the chest and abdomen for any signs of mesothelioma or other abnormalities. Chest X rays, CT scans and MRIs can all show changes in the lungs, such as pleural thickness or fluid accumulation. They can also reveal the extent to which mesothelioma is spreading to other organs of the body.

A doctor will also order an examination of the blood to determine whether the patient has high levels of certain substances that are linked to mesothelioma. They can also carry out a procedure called the thoracentesis. This involves removing a sample of the lungs' fluid to check 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 done using VATS (video-assisted thoracoscopic surgery) or with a needle guided by the aid of a CT scan. The results will help determine which mesothelioma treatments are the most effective for the patient. This can include surgery, chemotherapy or radiation therapy. Some patients also choose to undergo immunotherapy. This newer form can improve the prognosis of patients and improve their quality of life.

Treatment

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

Your doctor will inquire about your medical history and look for symptoms of mesothelioma. Your doctor will also ask about your exposure to asbestos legal, because it is the leading risk factor for mesothelioma. Exposure to asbestos legal can cause asbestos fibers to become trapped in the chest cavity's lining and tummy, or the heart (mesothelium). In time this causes inflammation and transforms normal cells into cancerous ones. Imaging tests and blood tests can be used to detect mesothelioma.

Your healthcare provider will use an X-ray chest scan to observe changes in your lung tissue and determine whether you have fluid build-up (pleural effusion). Your provider will order MRI, CT scan or FDG-positron emission tomography (PET) to obtain detailed images of the affected area. They may also perform an incisional needle biopsy to collect an in-situ sample of the affected tissue.

A mesothelioma specialist, also known as a pathologist will study mesothelioma cells under a microscope in order to find cancerous cells and determine what type of mesothelioma you suffer from. The pathologist will use a dye to stain the tissue samples to diagnose the cancer. The dye is visible when certain types of mesothelioma are present. They will then employ a special technique to get an even closer view of the tissue under a microscope.

It is sometimes difficult to diagnose mesothelioma because the mesothelioma-causing cells look similar to those of other types of cells within the body. Your care team will try to confirm the diagnosis by performing other tests. They may use blood tests to measure levels of fibulin-3 and mesothelin-related, soluble peptide.

Your healthcare team will determine the best treatment option for mesothelioma depending on your cancer type and stage. Radiotherapy, chemotherapy, and surgery are the most common treatments for mesothelioma. Palliative treatment may be offered if your mesothelioma has reached an advanced stage. This can relieve you of pain and other symptoms.

Prognosis

The prognosis for mesothelioma is determined by the stage and type of cancer as well as factors like age and general health. Patients should consult with knowledgeable doctors to find out more about their treatment options.

Mesothelioma develops when asbestos fibers damage the tissues that line and protect vital organs. These asbestos fibers can be breathed in or ingested, and over time they cause inflammation and genetic changes that transform normal cells into mesothelioma-related tumors. The most prevalent mesothelioma types are pleural mesothelioma that develops in the lung lining and chest cavity (pleura) as well as peritoneal mesothelioma, a rarer type that is found in the protective lining of the abdomen.

Mesothelioma is diagnosed by symptoms, laboratory tests and X-rays. They may also recommend a biopsy to confirm the diagnosis. A biopsy involves the removal of the tissue to be examined. Doctors can then compare the biopsy samples against a database to identify the most likely mesothelioma-related cell type. This information can be used to determine the longevity of a patient with mesothelioma and their treatment plan.

Mesothelioma cells are classified in three categories: epithelioid or epithelial, sarcomatoid and biphasic. Each mesothelioma kind develops at an individual rate and responds differently to treatment. Epithelioid mesothelioma is responsible for 60 percent to 80% of cases and has a higher survival rate than sarcomatoid and biphasic mesothelioma.

It can take up to 50 years for mesothelioma be diagnosed following exposure to asbestos, which is why many patients don't be diagnosed with mesothelioma until they begin to experience serious symptoms. Exposure to asbestos should be disclosed to a physician, and victims should be checked regularly.

During these visits, doctors will look for signs of asbestos exposure 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 indicate that the risk of a patient developing mesothelioma is high they can schedule additional tests to get a mesothelioma prognosis. This includes imaging tests like X radiations, CT scans, and ultrasounds, in addition to lung function tests and a chest MRI, or PET scan.
