SAN ANTONIO — Colonoscopies are a dreaded but necessary test to catch colorectal cancer. But a new test that could replace the standard colonoscopy could catch the disease without being nearly as invasive.
Guardant Health found that one way to boost colorectal cancer screening rates would be through an innovative blood test that would be a much more convenient option.
Dr. Victoria Raymond, the senior director of medical affairs at Guardant Health told us, "Blood based testing was seen as convenient, and something that people could easily complete as part of their routine health encounter. And that made it a much more attractive option for individuals to get screened."
What are the main barriers preventing people from getting screened? Dr. Raymond said the primary reason is because," people thought the current options were unpleasant. And then number two, because individuals were concerned about discomfort or fear from colorectal cancer screening."
According to Guardant Health, only 2/3 of adults ages 45 to 64 report being up to date on colorectal cancer screenings. That is 50 million Americans who are out of compliance. And, more than 3/4 of those who will die this year from colorectal cancer will have been behind on their screenings.
The Harris Poll found that 90% of Americans say a blood test option would make them more likely to stay up to date on screenings. Dr. Raymond added, "Oftentimes early stage colorectal cancer doesn't have any symptoms. And that's why screening is critical."
So at what age should people start getting screened? Dr. Raymond told us, "That's why screening is recommended for everyone age 45 years and older. For those individuals that are starting to have symptoms, you can look for things like blood in your stool or changes in your bowel pattern."
Raymond says if you have any of those symptoms to talk to your doctor about getting screened immediately. You can also find out more about the Guardant Health blood test HERE.
