Cancer and tumor marker tests detect specific substances in blood, urine, or tissue that signal cancer presence or treatment response. They include markers like PSA for prostate cancer, CA-125 for ovarian cancer, and CEA for various cancers. These tests aid in screening, diagnosis, treatment selection, and monitoring, though levels alone don't confirm cancer. They personalize care, enhance outcomes, and require interpretation by healthcare providers for optimum cancer management.

The Alpha-Fetoprotein (AFP) Test measures alpha-fetoprotein levels in blood, produced by the fetal liver. Elevated AFP levels in adults can signal conditions like liver cancer and certain liver diseases. As a tumor marker, the AFP test aids in diagnosing and monitoring liver cancer and testicular cancer, indicating tumor presence, treatment response, and cancer recurrence risk. It may be used with imaging studies to diagnose liver cancer and track treatment progress. While AFP elevation is common in liver cancer, other factors like benign liver conditions, pregnancy, or ovarian/testicular cancer can also raise levels. The AFP test is essential for evaluating and managing cancer and liver diseases, enabling early liver cancer diagnosis, treatment response monitoring, and recurrence risk assessment. Used alongside other tests and imaging, the AFP test guides personalized care for patients with specific cancers and liver conditions.
The amylase test detects amylase enzyme levels in blood or urine to diagnose pancreas-related conditions like pancreatitis or pancreatic cancer. Amylase, produced by the pancreas and salivary glands, aids in carbohydrate digestion. Elevated amylase levels can indicate pancreatic issues. Pancreatitis, an inflamed pancreas, often raises amylase levels, assisting in diagnosis and monitoring. This test also helps evaluate salivary gland, kidney, and gastrointestinal disorders. Monitoring amylase levels supports timely diagnosis, treatment, and management of pancreatic and related disorders, allowing healthcare providers to track treatment progress effectively.
The Beta-hCG test measures human chorionic gonadotropin levels in blood or urine, helping detect and monitor pregnancy. Often called the pregnancy hormone, hCG levels rise rapidly in early pregnancy, confirming pregnancy and tracking fetal health. The test also aids in diagnosing conditions like trophoblastic disease and certain cancers based on hCG levels. In pregnancy, it assesses gestational age and can identify complications like ectopic pregnancy. Used across clinical settings, the Beta-hCG test provides essential information for accurate diagnoses and effective treatment in obstetric and non-obstetric care.
The CA-125 test measures CA-125 protein levels produced by organs like ovaries, fallopian tubes, and the abdomen. Primarily linked to ovarian cancer, elevated CA-125 levels can indicate gynecological conditions. It serves as a tumor marker for ovarian cancer diagnosis and monitoring. While it aids in tracking treatment response and disease progression, elevated CA-125 levels can also be present in noncancerous conditions. Typically used in combination with other tests and imaging, serial CA-125 measurements assist in evaluating and monitoring ovarian cancer and related conditions. Additionally, it's beneficial in assessing diseases affecting the reproductive system. Healthcare providers use the CA-125 test for early detection, personalized treatment, and disease monitoring, particularly in ovarian cancer and gynecological conditions.
The ESR test measures the rate at which red blood cells settle in a tube over time and is used to diagnose or monitor inflammatory conditions like infections, autoimmune diseases, and cancer. A high ESR rate may indicate inflammation or infection, while a low rate is normal.
The lipase test measures levels of the enzyme lipase, vital for digesting fats and produced mainly by the pancreas. Elevated lipase levels in the blood often indicate pancreatitis, an inflammation of the pancreas due to issues like gallstones or alcohol consumption. This diagnostic test helps diagnose and monitor pancreatitis, assess its severity, treatment efficacy, and guide recovery. Besides pancreatitis, lipase testing can detect conditions affecting the pancreas, gallbladder, or digestive system, such as pancreatic cancer or gallbladder inflammation. Routine lipase monitoring aids healthcare providers in diagnosing and managing pancreatic and digestive disorders promptly. It is an essential tool for assessing pancreatic health, aiding in timely detection, treatment evaluation, and overall pancreatic and digestive system function assessment. Regular lipase testing is crucial for appropriately managing pancreatic conditions and related digestive disorders.
The PSA test measures levels of the prostate-specific antigen (PSA) in the blood, indicating various prostate conditions like cancer, BPH, and prostatitis. Mainly used for prostate cancer screening, elevated PSA levels may signal the need for further tests like a biopsy. The test also aids in monitoring prostate cancer patients for disease progression. While high PSA levels can suggest cancer, factors like BPH or prostatitis can also raise levels, requiring additional assessments for accurate diagnosis. The PSA test is vital for early prostate cancer detection and management. Healthcare providers rely on the PSA test to assess prostate health, guide cancer screening, monitor disease development, and tailor treatment plans.
