Female Speaker: John Shea suffers from both colon and prostate cancers. Going through chemotherapy is tough enough, but John says the biopsies for his prostate cancer were the worst part.
John Shea: I found it very painful. They had to take, I think it was 12 cultures, and it was like they took a Taser gun.
Female Speaker: Doctors are testing a circulating tumor cell machine that could make biopsies a thing of the past.
John Shea: Every time I came, they take a blood sample.
Female Speaker: A tablespoon of John's blood is filtered through the machine and placed onto a genetically-engineered chip about the size of a business card. The chip holds an antibody that traps abnormal cells.
Dr. Richard Lee: The chip itself is a breakthrough in engineering.
Female Speaker: Within six hours the machine analyzes the blood and can detect one cancer cell among one billion healthy blood cells.
Dr. Richard Lee: We would hope that we would be able to perhaps eliminate the invasive part.
Female Speaker: Routine blood tests tell doctors if John's chemo is working or if they need to be more aggressive; the same as biopsies, minus the discomfort.
John Shea: I wouldn't want to go through another one again.
Female Speaker: Taking some of the pain out of fighting cancer. I am Melissa Medalie reporting.
