the blood test discovered blood from DNA fragments released by cancerous tumours.
Examining DNA fragments for mutations found in cancer- causing genes leads to the discovery of blood of many early stage cancers. It exposed colon, breast, lung and ovarian cancers.
Early detection of cancers can leads to effective treatment from onset and save many lives, the test can screen out people without cancer. Genetic blood test for cancer must expose DNA mutations linked to cancer and ignore harmless mutations that is always present in healthy humans.
Exposing cancer and early treatment is the most important aspect of the discovery, differentiating deadly cancers that will hurt people from cancers that may not is very important for the success of the blood test.
