Blood Tests to Detect Cancer
Blood tests can be used to detect cancer in some cases. The most common type of blood test used to detect cancer is a complete blood count (CBC). This test measures the number of red blood cells, white blood cells, and platelets in your blood. Abnormal levels of any of these can be a sign of cancer.
Other blood tests can be used to detect specific types of cancer. For example, prostate-specific antigen (PSA) tests can be used to detect prostate cancer. Other types of cancer can be detected with a variety of blood tests, including the carcinoembryonic antigen (CEA) test, the alpha-fetoprotein (AFP) test, and the CA-125 test.
Imaging Tests to Detect Cancer
Imaging tests, such as X-rays, CT scans, MRI scans, and PET scans, can be used to detect cancer. These tests can be used to create images of the inside of your body and identify areas where cancer may be present.
Biopsy to Detect Cancer
A biopsy is the most accurate way to diagnose cancer. A biopsy involves removing a sample of tissue from the suspicious area and examining it under a microscope to look for cancer cells. The sample may come from a tumor or from other areas of the body where cancer may have spread.
Conclusion
Blood tests, imaging tests, and biopsies are the most commonly used methods to detect cancer. Depending on the type of cancer, one or more of these tests may be used to diagnose the disease. If your doctor suspects that you may have cancer, they will use the appropriate tests to determine a diagnosis.
