Blood Proteins Could Give Cancer Warning Seven Years Before Diagnosis! [Video]

Proteins linked to cancer can start appearing in people’s blood more than seven years before they’re diagnosed, our funded researchers have found. In the future, it’s possible doctors could use these early warning signs to find and treat cancer much earlier than they’re able to today.
Across two studies, researchers at Oxford Population Health identified 618 proteins linked to 19 different types of cancer, including 107 proteins in a group of people whose blood was collected at least seven years before they were diagnosed.
The findings suggest that these proteins could be involved at the very earliest stages of cancer. Intercepting them could give us a way to stop the disease developing altogether. This research brings us closer to being able to prevent cancer with targeted drugs – once thought impossible but now much more attainable.
For now, though, we need to do further research. The team want to find out more about the roles these proteins play in cancer development, how we can use tests to spot the most important ones, and which drugs we can use to stop them driving cancer.
Both studies, published today in Nature Communications, used a powerful technique called proteomics to find important differences in blood samples between people who did and did not go on to develop cancer.
