Cancer Early Warning System?

An Oxford University Nature Communications paper, analysed repeated blood samples from more than 44,000 subjects. Of these, 4,900 folk went on to have a cancer diagnosis. Scientists could consequently compare the blood proteins of subjects who did or did not go on to develop cancer. More than 600 proteins were linked to 19 types of cancer. These cancers included colon; liver; lung and non-Hodgkin's lymphoma (https://www.theguardian.com/society/article/2024/may/15/proteins-blood-cancer-warning-seven-years-study). In some cases, protein 'markers' were evident 7 years, before the cancer diagnosis. These proteins could provide the basis for a cancer early warning system. Cancer therapies generally work better, if applied early. Testing all individuals over an extended period would be costly. It also remains to be seen, whether all folk would want to know, if they carried a 'worrying' blood protein. Don't tell Life Assurance companies!
