Blood tests that can identify more than 20 types of cancer will be developed
By
Blood tests have been developed that can detect over 20 types of cancer, including those that are difficult to detect, such as pancreatic cancer and ovarian cancer . This test can identify 'which cancer' is accurate with 89% accuracy, and the misdiagnosis rate is low.

The blood test was developed by 'Grail', a company that finds cancer from blood, which became a hot topic when Bill Gates and Jeff Bezos invested.

The developed blood test is to examine the DNA methylation pattern of cell-free DNA in the blood. Cell-free DNA is DNA that is released into the blood when blood cells die, but it also flows when immunity destroys cancer cells. Cell-free DNA released by cancer cells may have an abnormality in “DNA methylation”, which results in hydroxylation of methyl groups in the DNA. Therefore, you can tell if you have cancer by examining the blood.

Jeffrey Oxnard, a member of the Dana-Farber Cancer Institute at Harvard Medical School, analyzed blood from 1500 cancer patients and blood from 2000 non-cancer patients using a blood test developed by Grail The we. As a result of the analysis, regarding the detection rate of cancer with a high mortality rate, the detection rate of stage I cancer is 32%, the detection rate of stage II cancer is 76%, and the detection rate of stage III cancer is 85% The detection rate for stage IV cancer was 93%, and it was only 0.6% for misdiagnosis that 'you are diagnosed with cancer even though you have no cancer'.
In addition, the cancers affected by the subjects included breast cancer, rectal cancer, esophageal cancer, gallbladder cancer, stomach cancer, head and neck cancer, lung cancer, acute lymphocytic leukemia, ovarian cancer, pancreatic cancer, etc. More than one type of cancer was included. The blood test said that the 'primary site' where cancer first developed in the body was identified with an accuracy of 89%.
Oxnard commented, 'If this blood test becomes common, a large number of cancer patients may be able to receive efficient treatment, even with a low detection rate.' .
