What cancers are not detected by blood tests?
During the trial, 24 additional cancers not identified by the blood test were picked up by standard screening: 20 breast cancers, 3 lung cancers, and 1 colorectal cancer. Of the 24 cancers, 22 were early-stage cancers.
What cancers are detected by blood tests?
What types of blood tests can help detect cancer?
- Prostate-specific antigen (PSA) for prostate cancer.
- Cancer antigen-125 (CA-125) for ovarian cancer.
- Calcitonin for medullary thyroid cancer.
- Alpha-fetoprotein (AFP) for liver cancer and testicular cancer.
When should I get checked for cancer?
All people at average risk should start testing at age 45, so talk to your health care provider if you haven’t started yet. There are several testing options. Talk with a health care provider about which tests are best for you and how often testing should be done.

How do doctors detect cancer?
Laboratory studies of blood, urine, and stool can detect abnormalities that may indicate cancer. When a tumor is suspected, imaging tests such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and fiber-optic endoscopy examinations help doctors determine the cancer’s location and size.
What blood levels indicate cancer?
Tumor marker tests used to diagnose cancer include: A CA-125 test measures the amount of the cancer antigen 125 (CA-125) in a person’s blood. CA-125 is a protein that is a biomarker or tumor marker. The protein is found in higher concentration in cancer cells, particularly ovarian cancer cells.
How does blood test determine cancer?
Cancer blood tests work by screening for DNA released by dying tumor cells. These tests are showing promise for detecting traces of tumor DNA in the blood of cancer patients. However, the results don’t indicate where the tumor resides.
Can a routine blood test detect cancer?
Routine Blood Test May Detect Cancer. A routine, but highly sensitive, blood test may be able to detect cancer. Researchers from Stanford University School of Medicine have found a way to monitor levels of tumor DNA circulating in the blood.
