A new blood-based test for colorectal cancer currently up for FDA review could mean cheaper and less invasive screenings for the disease.
“The idea of a blood-based test is something they’re used to having done. And that can be done as part of their routine medical care, I think that will encourage more people to be screened, which I think is good news,” said Dr. William L. Dahut, chief scientific officer of the American Cancer Society.
“I wasn’t familiar with the different stages. I wasn’t really even too familiar with cancer, to be honest,” said Smith. Colonoscopy screenings are the recommendation for those aged 45 and up. In a colonoscopy, a patient is sedated while a camera is used to show the inside of their rectum and large intestines. If a doctor finds a growth or polyp they can remove it before it becomes cancerous. There are also at-home tests where patients mail in their own stool sample.
“Over 50 million eligible Americans do not get recommended screenings for colorectal cancer, partly because current screening methods are inconvenient or unpleasant,” said AmirAli Talasaz, Guardant Health co-CEO in a press release.
