Is Mesothelioma a Lung Cancer?
Mesothelioma can begin in the tissues that cover every lung (the Pleura) or, in a less frequent manner it can be found in the lining of the tummy (peritoneum). The disease is most often diagnosed in the latter stages and symptoms can take anywhere from 10 to 50 years before they appear.
Doctors make use of imaging tests and biopsies to identify mesothelioma. Treatment plans typically comprise chemotherapy, surgery and/or radiotherapy.
Pleural mesothelioma
The lung's lining is usually affected by pleural mesothelioma. It is the most common mesothelioma type and patients tend to have a better prognosis than those who are diagnosed with other types of mesothelioma like mesothelioma of the pericardial region or peritoneal.
When a patient complains about lung problems such as shortness of breath or coughing Doctors may suspect the presence of pleural asbestosis. They then order a series of tests to establish an official diagnosis. This includes x-rays, CT scans and MRIs along with blood work and a biopsy. To perform a biopsy, doctors insert a thin, light tube known as a thoracoscope into the chest and between two ribs.
The symptoms of mesothelioma may be similar to other illnesses, making it hard to diagnose the disease early. There are some people who do not show symptoms at all, and when they do, the initial signs are usually dismissed as pneumonia or other less serious illnesses. The best chance to receive an accurate diagnosis is to visit a mesothelioma specialist or go to mesothelioma clinics. Mesothelioma specialists have more experience with the rare disease and will be able to recognize the symptoms more easily.
If a mesothelioma-related diagnosis is made, doctors will plan the best treatment options for each individual patient. They will consider the stage of mesothelioma as well as the kind of cancer cells, and where they are located. Patients with pleural mesothelioma in an earlier stage are likely to have a better chance of survival compared to those with mesothelioma that is later in its stage. This is because the cancerous cells are localized.
Patients with pleural msothelioma could benefit from chemotherapy, surgery and radiation. Palliative care is also recommended to alleviate symptoms and improve quality of life.
Although mesothelioma can't be treated but it can be treated to prolong the life span of the patient. Like all forms of mesothelioma, it's essential to seek treatment as soon as you can, so that doctors can get to work on creating an appropriate treatment strategy.
Peritoneal mesothelioma
A person who is diagnosed with peritoneal mesothelioma has cancer in the abdomen's lining or chest cavity. Similar to pleural mesothelioma, the symptoms can include breathing difficulties, pain and fluid accumulation. The person may also feel nauseated and spit up. In addition to chemotherapy and surgery A doctor might recommend palliative specialist treatment to ease symptoms and improve quality of life.
Doctors determine if peritoneal mesothelioma is present by scanning scans of the abdomen or chest. A biopsy may be needed to confirm the diagnosis. In a biopsy, doctors take a small amount of tissue or fluid from the tumor to examine under a microscope.
The most common indication of peritoneal mesothelioma is abdominal pain that feels spread out or confined to one area. Other signs can include a cough that doesn't disappear or subsides, as well as weight loss and fever. The prognosis of a mesothelioma patient is based on many factors including the type of cell and the stage of the disease. The gender of a person can also influence their prognosis. Women and people assigned female at birth have better outcomes with mesothelioma of the peritoneal region than males and those assigned male at birth.
Mesothelioma can be caused by changes (mutations) in the DNA of cells. This mutation causes the cells to expand and multiply out of control. The cancerous cells may then form a tumour, or collection abnormal cells.
The majority of people diagnosed with mesothelioma work working in jobs which expose them to asbestos. Asbestos is a fibrous material that was once used in construction, plumbing electrical work, as well as the automobile industry. Asbestos exposure can cause mesothelioma.
Malignant mesothelioma is often difficult to treat when it is advanced. Doctors may suggest surgery, chemotherapy or radiation therapy to treat mesothelioma. These treatments are designed to target the cancer cells without harming healthy ones. Combining them will give patients a better chance at finding a cure. Doctors will decide which treatment is best based on the patient's cancer stage, general health and individual preferences. They might also suggest promising new therapies for treating mesothelioma.
Extrapleural pneumonectomy (EPP)
Extrapleural pneumonectomy is a mesothelioma procedure that can be carried out on patients suffering from pleural mesothelioma that are healthy enough to undergo surgery. In this procedure, doctors remove the lung affected by the disease, as well as a portion of the mesothelioma lining that surrounds it. In certain instances doctors may also remove the diaphragm and the pericardium. This is among the mesothelioma treatment options that are most effective. Specialized mesothelioma doctors perform EPP in mesothelioma peritoneal cancer mesothelioma treatment facilities across the United States.
Specialists in mesothelioma perform various tests to determine whether a patient is fit for surgery. PET and CT scans as mediastinoscopy are a few of the tests that can be performed. These tests allow doctors to see the tumors, and how far they have been able to spread. If mesothelioma has gotten too far for surgery doctors will resort to chemotherapy to shrink or stabilize tumors.
The goal of mesothelioma therapies is to prolong life expectancies and improve quality of living. But mesothelioma suffers from a long latency period and it can be difficult to diagnose early. This is why many patients have already begun to show symptoms by the time they are diagnosed.
Doctors generally recommend patients go through multiple treatment options as part of a multimodal treatment. The reason is because mesothelioma treatment by itself is not effective. Combining treatments maximizes their effects. For instance, radiation therapy, can reduce the size of mesothelioma before surgery. This makes it easier to remove. Doctors have also tried using high-energy radiation prior to EPP (known as SMART) and it has helped prolong the life expectancy of mesothelioma patients.
EPP is a mesothelioma-related procedure that requires general anesthesia. Once the anesthesia has taken effect, the surgeon will make either an sternotomy of 9 inches (front of the chest) or the thoracotomy, which is 10-inches long (front of chest). The surgeon will then separate the chest wall and lungs from any other organs.
This is a potentially risky procedure and only patients with mesothelioma in good health who are physically fit to undergo the procedure. After the procedure, patients are expected to spend few weeks in hospital. They will then need to recover at home or a rehabilitation center.
Trimodality therapy
Three standard treatments are available for mesothelioma - radiation therapy, surgery and chemotherapy. Doctors may also employ a combination of all three (called multimodality therapy). Survivors have different treatment options based on what mesothelioma type they suffer from and the extent to which it has spread.
The first step to treat mesothelioma is obtaining an accurate diagnosis from an expert in mesothelioma. Mesothelioma can be difficult to identify because cancerous cells may appear similar to normal cells. Doctors typically test fluid or tissue samples for mesothelioma-related cells to confirm a diagnosis. The medical history of the patient is another important element of information doctors can use to determine if mesothelioma was the likely cause.
The symptoms of mesothelioma can include coughing, chest pain and breathing problems. Doctors may order an X scan or CT scan to look for abnormal thickening in the lung's lining, calcium deposits, and the accumulation of fluid. A doctor may also perform biopsy procedures, where they take a small amount of the tumor and surrounding tissues for testing.
Other imaging tests that doctors typically utilize to determine how advanced mesothelioma has become include positron emission tomography (PET) and magnetic resonance imaging (MRI). These tests require taking images of the body by using magnetic fields and radio waves. The mesothelioma cells absorb the radioactive atoms in these tests, and they show up brighter on the images than healthy cells.
If mesothelioma has spread to the pleura (the lung's lining), doctors may perform surgery to stop it. Depending on the stage of the disease, this may be an extrapleural pneumonectomy (EPP), a more extensive operation that involves the removal of the affected lung and part of the diaphragm, or pleurectomy with decortication (P/D). These surgeries are typically performed in conjunction with other treatments for mesothelioma, such as chemotherapy or radiation.
Chemotherapy is the process of using drugs to kill cancer cells and improve the quality of life. Pemetrexed is a chemotherapy drug used to treat pleural mesothelioma can be administered as a single drug or in combination with carboplatin and cisplatin. For mesothelioma peritoneal chemotherapy is usually administered intravenously. Patients can receive chemotherapy as an outpatient from Monday through Friday for 4-7 weeks.
