BREAKTHROUGHS IN CANCER DETECTION: New tests promise to revolutionize cancer diagnosis. Dr. Gary Goldman is a board-certified ob-gyn and one of America’s leading Functional Medicine practitioners, and is also a member of the speakers’ bureau for Grail, developer of the Galleri cancer test. What are some of the limitations of current cancer tests like mammography, colonoscopy, PSA, CA-125, PAP smears, and CT scans? What’s the difference between sensitivity and specificity? How does the Galleri test enhance our ability to detect cancers? How was it developed? How accurate is it? Will it lead to overdiagnosis? Why is there controversy over a £140 million NHS trial using Galleri to detect cancer? Can “liquid biopsies” be used to find out whether cancer is recurring before it’s visible on imaging? What about new genetic tests that predict your likelihood of developing cancer? Why the arguments over frequency of colonoscopies, mammograms and PAP smears? Is there a certain age when you can forego them? Is the new colon cancer blood test a good alternative to colonoscopy?
