so that's the new area of hot research so in the past we could essentially only detect these cancers based on Imaging so these metastases would have to grow to a certain size like 1 millimeter 2 millimeters before they would show up on these scans so small numbers of cancer cells we couldn't detect and so you're waiting many many years you know doing a follow-up scan five years later and all of a sudden you see a spot on the lungs or a spot on the liver and say okay that could be cancer so um this whole idea of can we find them earlier through um blood tests what they're calling liquid biopsies and this is an area of a lot of research now
