Dr. Charles Mok explains why MRI cannot replace standard cancer screening. MRI misses skin, breast, prostate, and colon cancers, so stick with colonoscopy, mammograms, and skin checks. A blood test called Galleria Grail detects tumor fragments but struggles with early-stage disease.

What does it miss? It's not good for skin cancer. The way we're doing it now is not good for breast cancer. It's not good for prostate cancer, not good for colon cancer. That being said, we don't want people to think this is an alternative to routine screening. It's an addition to. So you still get your skin check, still your colonoscopy, still get your mammogram, still get your PSA blood test. There's something called a 3D MRI of the prostate that does is better for picking up prostate cancer. So if you have a specific genetic risk, it's actually a separate test. The test is called the Galleria Grail. It came out, there's a big splash because it picks up fragments of DNA from cancer. The problem has been it's not good at picking up cancer at early stages. But the price is coming down all the time. I get the question, doc, what's the best test that I can get? And my answer is all of them.
