Doctors use many tests to find, or diagnose, cancer. They besides do tests to learn if cancer has spread to another part of the body from where it started. If this happens, it is called metastasis. For example, imaging tests can show if the cancer has spread. Imaging tests show pictures of the inside of the body. Doctors may besides do tests to learn which treatments could work good .
For most types of cancer, a biopsy is the entirely certain direction for the doctor to know if an area of the soundbox has cancer. In a biopsy, the sophisticate takes a little sample of weave for testing in a lab. If a biopsy is not possible, the doctor of the church may suggest other tests that will help make a diagnosis .
This segment describes options for diagnosing mesothelioma. not all tests listed below will be used for every person. Your doctor of the church may consider these factors when choosing a diagnostic test :
Reading: Mesothelioma: Diagnosis | Cancer.Net
- The type of cancer suspected
- Your signs and symptoms
- Your age and general health
- The results of earlier aesculapian tests
The diagnosis of mesothelioma is challenging, and it can be confused with other diseases, such as lung cancer .
many people first notice symptoms of mesothelioma when they develop fluid in the space around the lungs or in the abdomen. Fluid around the lungs is called pleural effusion. Fluid in the abdomen is called ascites .
In accession to a physical examination, the follow tests may be used to diagnose mesothelioma :
Testing fluid from the lungs or abdomen. After numbing the bark, a needle is inserted into the space between the lung and the wall of the chest or in the abdomen. When the fluid is removed, it can be analyzed to find out if there are cancer cells in it. This is frequently 1 of the first steps in diagnosing mesothelioma. however, testing this fluid is normally not the only examination needed to diagnose the disease. A biopsy is normally needed to diagnose mesothelioma .
Biopsy. A biopsy is the removal of a small sum of tissue for interrogation under a microscope. early tests can suggest that cancer is present, but entirely a biopsy can make a definite diagnosis. A diagnostician then analyzes the sample ( mho ). A diagnostician is a sophisticate who specializes in interpreting testing ground tests and evaluating cells, tissues, and organs to diagnose disease. A biopsy is normally needed to confirm a diagnosis of mesothelioma. sometimes, a needle can be used to get a sample of the line. More often the repair removes a tissue sample by using a sparse, lighted tube inserted through a little incision in the body. This is called a video thoracoscopy when used to get samples from inside the breast. It is called a laparoscopy when used to get tissue samples from inside the abdomen. sometimes, operating room is needed to get a sample distribution of weave .
The come procedures may be used to determine the cancer ’ south stage and help develop a treatment plan :
Physical examination and health history. Your repair may do a physical examination and ask you questions to learn more about your health history and your risk of mesothelioma. This may include :
- Asking about your checkup history and your kin ’ mho by illnesses
- Asking about your history of exposure to possible hazard factors for mesothelioma, including asbestos exposure
- Doing a physical examination to look for early signs of cancer and to check your current health .
Blood tests. Your doctor of the church may recommend respective blood tests to find out how good your kidneys, liver, thyroid, and bone marrow are working.
Lung function tests. besides called pneumonic serve tests or PFTs, lung function tests evaluate the trace :
- How much air travel the lungs can hold
- How promptly publicize can move in and out of the lungs
- How well the lungs add oxygen and remove carbon dioxide from the lineage .
X-ray. An x-ray is a way to create a picture of the structures inside of the body using a minor sum of radiation. It is not the main way to diagnose mesothelioma. But a chest x-ray can sometimes serve doctors determine whether a person has mesothelioma and where it is located .
Computed tomography (CT or CAT) scan. A CT scan takes pictures of the inside of the body using roentgenogram taken from different angles. A calculator combines these images into a detail, three-dimensional image that shows abnormalities or tumors. A computerized tomography scan can be used to measure the tumor ’ south size. sometimes, a special dye called a contrast average is given before the scan to provide better detail on the trope. Depending on the part of the body being looked at, this dye can be injected into a affected role ’ randomness vein or given as a pill or liquid to swallow.
Magnetic resonance imaging (MRI). An MRI uses magnetic fields, not x-rays, to produce detailed images of the body. MRI can be used to measure the tumor ’ randomness size. A special dye called a line medium is given before the scan to create a clear picture. This dye can be injected into a patient ’ randomness vein or given as a pill or fluid to swallow .
Positron emission tomography (PET) or PET-CT scan. A PET scan is normally combined with a CT scan ( see above ), called a PET-CT read. however, you may hear your doctor of the church denote to this procedure just as a PET scan. A positron emission tomography scan is a means to create pictures of organs and tissues inside the soundbox. A small sum of a radiolabeled carbohydrate kernel is injected into the patient ’ south body. This carbohydrate meaning is taken up by cells that use the most energy. Because cancer tends to use energy actively, it absorbs more of the radiolabeled means. A scanner then detects this substance to produce images of the inside of the torso.
Molecular testing of the tumor. Your doctor may recommend running lab tests on a tumor to identify specific genes, proteins, and early factors unique to the tumor. Results of these tests can help determine your treatment options.
After diagnostic tests are done, your doctor will review all of the results with you. If the diagnosis is cancer, these results besides help the doctor of the church describe the cancer. This is called staging .
The future section in this guidebook is Stages. It explains the system doctors use to describe the extent of mesothelioma. Use the menu to choose a different segment to read in this template .
