Lung Cancer From Mesothelioma
Mesothelioma usually occurs in the thin layer of tissue that lines your lungs (pleura) or abdomen (peritoneum). The symptoms are similar to the signs of lung cancer.
X-rays and CT scans can be utilized by doctors to diagnose mesothelioma. They can also conduct an PET scan, which utilizes radioactive compounds to aid doctors in locating cancerous cells.
Signs and symptoms
Mesothelioma is a rare cancer that is found in the lining of organs, such as the lungs and chest cavity. It is caused by exposure to asbestos, a grouping of minerals which includes microscopic fibres that are used in construction materials as well as other materials. Exposure can occur at work or at home. After exposure, the symptoms of mesothelioma may last between 10 and 40 years. The symptoms of mesothelioma may be similar to those of lung cancer. This makes it difficult to diagnose.
Lung cancer and mesothelioma have similar symptoms, including chest pain, breathing difficulties and fatigue. Some mesothelioma patients experience build-up of fluid around the lungs that doctors refer to as pleural effusion. The fluid causes breathing difficulties and lung cancer can spread to other body parts including the abdomen and the heart.
Doctors follow a number of steps to identify mesothelioma. They will start by conducting a physical exam and ask about any asbestos exposure. They will also inquire about any symptoms that the patient has. Imaging tests are used to determine how the lungs, and other organs, are functioning. These include X-rays (or CT scans), MRIs (or magnetic resonance imaging) and PET scans (positron emission Tomography).
The doctor can also order blood tests to check for high levels of specific substances. If the doctor suspects mesothelioma, they will conduct an invasive lung biopsy to make a more precise diagnosis. A needle is placed into the chest cavity.
Palliative care can be a viable alternative to chemotherapy, surgery and radiation for some patients. It aims to control symptoms. Doctors can drain fluid from the lungs to improve breathing and prescribe strong painkillers for patients to reduce discomfort.
Although mesothelioma is not curable however, treatment options can enhance the quality of life for a patient. The use of aggressive surgery and multimodal therapy can slow the growth of tumours for a period of months or even years. Some patients have seen their tumours go into Remission. However, mesothelioma can recur and spread to other areas of the body. The best method to increase the chance of survival is to receive treatment in the early stages.
Diagnosis
Mesothelioma can be described as a cancer that originates from the mesothelium, the membrane that lines the body's cavities. Three out of four cases of mesothelioma start in the lining (pleura) of the chest cavity. Mesothelioma may also grow in the tissue that lines the abdomen or the area around the heart.
Symptoms of lung cancer from mesothelioma are similar to symptoms of other types of non-small cell lung cancer, or NSCLC like persistent coughing, difficulty breathing, hoarse voice, weight loss, and fatigue. Doctors must differentiate between NSCLC and Mesothelioma because they have different prognoses. Doctors will order diagnostic tests to check for signs of illness and the growth of tumors in order to determine if mesothelioma is the cause.
An X-ray is usually the first test that may reveal abnormal thickening or calcium deposits in the lungs. mesothelioma lung transplant can also test for a buildup of fluid in the lungs that could indicate mesothelioma and lung cancer.
A chest CT scan can be used to test the pleura (the space between the lungs and the chest wall) for indications of mesothelioma. These images can help doctors identify cancerous tissues and determine if mesothelioma has spread.
Other tests to diagnose mesothelioma pleural include fluid and blood tests, as well as a biopsy. Mesothelioma cells are tested in a fluid sample or a tissue sample. The cells are not found in normal lung tissues. Mesothelioma cells are classified into three types of epithelial (epidermal) and Sarcomatoid (sarcomatoid) and mixed or biphasic. A biopsy involves inserting a needle in the region in which the fluid is and taking a small sample to be examined under microscope.
VATS is a video-assisted procedure that allows for the collection of a biopsy. Another alternative is a CT-guided needle core biopsy, which uses a needle guided by a CT scan.
The use of radiation therapy is to treat the pleural msothelioma. The treatment is a process that sends high-energy X-rays towards cancerous tissues, and kills them. It is typically administered in conjunction with chemotherapy and surgical procedures for mesothelioma. Chemotherapy drugs such as carboplatin and pemetrexed are used to kill cancerous tumor cells and prevent them from recurring following surgery.
Treatment
The kind of treatment you will receive is based on the type of mesothelioma you have, how advanced it is, as well as your general health. Your doctor will also ask if you would like to participate in a clinical study of the latest treatment.
Mesothelioma doctors can use a variety of methods in conjunction to treat mesothelioma pleural. These include surgery, chemotherapy and radiation therapy. These treatments are used to shrink the tumors, reduce growth and eliminate any remaining cancer cells following other treatments.
Surgery to remove a lung and the surrounding tissue can ease symptoms of mesothelioma pleural. This can make it easier to undergo treatments for cancer like chemotherapy and radiation, because your chest is no longer protected by the lung.
Doctors can combine chemotherapy and surgery to increase the chances of an effective response. Researchers are constantly testing new combinations. The most well-known is a combination of pemetrexed and Cisplatin (Alimta). Radiation therapy is the use of radiation to kill cancerous cells. It is available in various stages of pleural msothelioma before or after chemo and surgery. It can ease the pain caused by tumors and can also be used to kill any cancerous cells that remain after chemo.
If doctors determine that mesothelioma cannot be removed it is possible to suggest palliative treatment to alleviate symptoms and improve the quality of life. This can include procedures to prevent fluid buildup in the lungs, such as thoracentesis/paracentesis or pleurodesis. These include treatments that reduce the shortness or coughing, such as oxygen pumps or Nebulizers. It is crucial for patients to discuss these options with their doctors. They may be able access care and support services through their local mesothelioma support group.
Prognosis
The prognosis of mesothelioma-related lung cancer is contingent on the type and location of mesothelioma, its stage at diagnosis and general patient health. Lung cancers that spread (metastasize) to other body parts usually have a worse prognosis than cancers that remain localized to the lungs. NSCLC and Mesothelioma are identified with a variety tests and procedures.
Mesothelioma is a type of cancer that develops in the tissues that line the chest cavity, abdomen and other organs. Mesothelioma is usually found in the tissues that line the lung (called the Pleura). Mesothelioma may also develop in the vicinity of the heart, or in the linings of the stomach testicles, stomach and intestines.
Symptoms of mesothelioma can resemble symptoms of other types of cancer or disease. Therefore, it is important that patients see their doctors if they experience these symptoms. A doctor can determine the difference between mesothelioma and lung cancer depending on the patient's medical history, symptoms, and general health.
A biopsy can be used to identify mesothelioma. This involves taking a small amount of tumor cells and examining them in an laboratory. A doctor can also search for signs of asbestos exposure by using the use of a CT scan that includes intravenous contrast or a lung function test.
A person's mesothelioma prognosis depends on which cell type they have: epithelioid, sarcomatoid or biphasic. Epithelioid cells generally have a better prognosis because these are easier to identify and eliminate through surgery. Patients with sarcomatoid cancer cells have a worse prognosis because they are more aggressive and grow faster.
Mesothelioma can be difficult to recognize because the symptoms are similar to those of other diseases or conditions. Certain patients are not diagnosed until the cancer is at an advanced stage. A mesothelioma expert can give more hope by providing an additional opinion, examining the options for treatment and clinical trials that test new drugs. Patients with mesothelioma should not be discouraged if they hear their doctor's estimation of life expectancy. A second opinion could make the difference.
