Johns Hopkins researchers found circulating tumor cells that signal colorectal cancer years before a colonoscopy can detect it. The discovery could catch tumors far earlier than current screening methods allow.
I mean, when you look at colonoscopies, colorectal cancers, it is known today that CTCs are dispersed from colorectal tumors well before they're detectable on imaging. Wow. Before they're detectable on colonoscopy. Yeah. Wow. They had data that came out from Johns Hopkins, I think, about a month ago, maybe three weeks ago, that just very recent data that's showing that they had tumor signals that were detectable three years before they could detect it with standard processes. So tumors typically are not born overnight. I mean, you can have some really rare, aggressive mutation, but these things are slow, and they're indolent, and they start years and years before we start seeing them or the symptoms. And so there are these cells floating around there. Is that tumor there quite early, and that's the power of being able to detect it at a cellular level.
