Early detection of pancreatic cancer is crucial to improve outcomes and increase the chances of successful treatment
Dr Dharani Chinnala, Consultant Histopathologist at TRUSTlab Diagnostics shares the tests that can be performed to detect pancreatic cancer.
Pancreatic cancer is one of the most difficult forms of cancer to detect and treat. It often goes unnoticed until it reaches an advanced stage, making it difficult to treat effectively. However, there are several important tests that can help detect pancreatic cancer in its early stages, when treatment is most effective.
One of the key tests used to detect pancreatic cancer is imaging tests. These tests allow doctors to visualize the pancreas and surrounding areas to look for abnormalities. A common imaging test used for this purpose is computed tomography (CT). During a CT scan, multiple x-ray images are taken from different angles to create detailed cross-sectional images of the pancreas. CT scans can help identify tumors, as well as any spread of cancer to nearby tissues or organs.
Another imaging test that can be used to detect pancreatic cancer is magnetic resonance imaging (MRI). MRI scans use magnetic fields and radio waves to produce detailed images of the pancreas and surrounding structures. Like CT scans, MRIs can help identify tumors and determine the extent of the cancer's spread.
In addition to imaging tests, blood tests may also be helpful in detecting pancreatic cancer. One such blood test is the CA 19-9 test, which measures the levels of a protein called CA 19-9 in the blood. Elevated CA 19-9 levels may indicate the presence of pancreatic cancer, although this test is not always accurate and may also be elevated due to other conditions.
Another blood test that can be used to detect pancreatic cancer is the CEA (carcinoembryonic antigen) test. Similar to the CA 19-9 test, elevated levels of CEA in the blood may suggest the presence of pancreatic cancer, but this test is also not specific for pancreatic cancer and may also be elevated in other conditions.
Endoscopic testing is another important tool in the detection of pancreatic cancer. One such test is endoscopic ultrasound (EUS), which involves inserting a thin, flexible tube with an ultrasound probe attached through the mouth and into the digestive tract. The ultrasound probe emits sound waves that create detailed images of the pancreas and surrounding structures. EUS can help identify small tumors and determine the extent of the cancer's spread.
Another endoscopic test that can be used to detect pancreatic cancer is endoscopic retrograde cholangiopancreatography (ERCP). During an ERCP, a flexible tube is passed through the mouth and into the digestive tract, allowing doctors to inject contrast dye into the pancreatic and bile ducts. X-ray images are then taken to look for blockages or abnormalities in these ducts, which may indicate the presence of pancreatic cancer.
Finally, a biopsy can be performed to definitively diagnose pancreatic cancer. During a biopsy, a small sample of tissue is taken from the pancreas and examined under a microscope to look for the presence of cancer cells. Biopsies can be performed using a variety of techniques, including fine-needle aspiration (FNAC) or surgical biopsy.
In conclusion, early detection of pancreatic cancer is crucial to improve outcomes and increase the chances of successful treatment. Various tests, including imaging tests, blood tests, endoscopic tests, and biopsies, can help detect pancreatic cancer in its early stages. If you experience symptoms such as abdominal pain, jaundice, unexplained weight loss, or changes in bowel habits, it is important to consult a healthcare professional who can recommend appropriate testing for further evaluation. Early detection and prompt treatment offer the best hope for effectively controlling pancreatic cancer.
