As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
A new blood test was found to detect colon cancer with more than 80% accuracy — and to rule it out for 90% of healthy people. Doctors speak about how this could improve screening rates and outcomes.
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [1] [2] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [3]
The Prostate Health Index (PHI) is a PSA-based blood test for early prostate cancer screening. It may be used to determine when a biopsy is needed. [32] [46] Prostate cancer antigen 3 is a urine test that detects the overexpression of the PCA3 gene, an indicator of prostate cancer. [32] [46] [47] [44]
Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [2] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging. [2]
Many screening tests involve the detection of cancers. Screening is more likely to detect slower-growing tumors (due to longer pre-clinical sojourn time) that are less likely to cause harm. Also, those aggressive cancers tend to produce symptoms in the gap between scheduled screening, being less likely to be detected by screening. [33]
