How to Know If You Have Brain Cancer: Diagnosis Choices
Brain cancer is a serious condition that requires prompt diagnosis and treatment. Identifying the presence of brain cancer involves a comprehensive evaluation of symptoms and the use of various diagnostic tests. In this article, we will explore the diagnostic choices available for determining if you have brain cancer.
The initial step in the diagnostic process is to assess the individual's symptoms. While these symptoms can vary depending on the location and size of the tumor, some common indicators of brain cancer include persistent headaches, seizures, changes in vision or hearing, difficulty with coordination and balance, cognitive impairments, and personality changes. If you experience any of these symptoms, it is crucial to seek medical attention for a proper evaluation.
Once the symptoms raise suspicion of brain cancer, healthcare professionals rely on a range of imaging tests to confirm the diagnosis. The most commonly used imaging techniques include magnetic resonance imaging (MRI) scan, computed axial tomography (CAT or CT) scan, and positron emission tomography (PET) scan.
CAT scans involve specialized x-ray tests combined with computer technology to produce detailed images of the inside of the brain and brain stem. This imaging technique allows doctors to examine the brain for the presence of tumors. Unlike standard x-rays, CAT scans provide cross-sectional views that offer a more accurate assessment of the brain's soft tissues. Often, a dye is injected into the body to enhance the contrast between abnormal and healthy tissue. CAT scans have been in use since the mid-1970s and continue to be a valuable tool in diagnosing brain cancer.
MRI scans, on the other hand, employ magnetic and radio waves to create detailed images of the body's internal structures, including the brain. Similar to CAT scans, MRI scans provide visualization of soft tissues, enabling doctors to detect abnormalities. One advantage of MRI scans is their ability to capture images from various angles, offering a comprehensive view of the brain. Many institutions consider MRI as the primary method of diagnosis due to its versatility. MRI technology has been in use since the 1980s and has significantly contributed to the detection and characterization of brain tumors.
PET scans, although less commonly used for diagnosing brain cancer, can provide additional information about the tumor. This technique involves injecting a short-lived radioactive isotope into the body, which allows for imaging of the body tissues. PET scans are often combined with CAT scans to obtain a more comprehensive picture of the tumor and its metabolic activity. While PET scans have been available since the 1950s, their use in brain cancer diagnosis is more limited compared to CAT and MRI scans.
In the past, skull x-rays were widely employed for brain cancer diagnosis. However, with the advent of more advanced imaging technologies, such as CAT and MRI scans, skull x-rays have largely been replaced in diagnostic procedures. Nowadays, different institutions may prefer one of the aforementioned scans as the initial diagnostic test based on their resources and expertise.
If a tumor is detected through imaging tests, a biopsy of the tissue is typically performed to establish an accurate diagnosis. A biopsy involves the surgical removal of a small portion of abnormal tissue, which is then sent to a laboratory for microscopic examination. This examination allows a pathologist to determine the type of cells present in the tumor, assess their degree of invasiveness, and evaluate the growth rate. This information is crucial in determining the malignancy of the tumor and guiding appropriate
