Less invasive alternative to colonoscopy set for 2011 clinical trial
A Madison, Wis., company is developing a less invasive way of screening for colon cancer that it hopes will take the place of uncomfortable colonoscopies and increase the number of people willing to be screened for colorectal cancers. Exact Sciences Corp., has developed a DNA-based test that can detect colorectal cancer through a stool sample. Even more convenient than a colonoscopy for the patient, the test can be administered at home and sent to a lab for analysis.
