Implantable device for cancer monitoringSurgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but only offer a snapshot of the tumor at a single moment in time.
Monitoring a tumor for weeks or months after the biopsy, tracking its growth and how it responds to therapy, would be much more valuable, says Michael Cima, MIT professor of materials science and engineering, who has developed the first implantable........Go to the Cancer-blog (Added on 5/14/2009 5:22:21 AM)
