Blood will tell

Blood tests known as ‘liquid biopsies’ could represent a major step forward in our ability to detect and monitor breast and other cancers


women diagnosed with early breast cancer had blood samples taken regularly for up to five years after treatment

Detecting DNA


different mutations were found that could distinguish cancer DNA in the blood and could be tracked over time


out of 144 women (101 in this group, plus others from a previous study) saw their breast cancer return after three years


of these women had cancer DNA detected in their blood prior to relapse

“By identifying relapse much earlier, we hope to treat it more effectively, and perhaps even prevent it”


months – the average time before clinical diagnosis that liquid biopsies spotted the signs of recurrence
