Residents of Houston’s Fifth Ward live adjacent to documented creosote contamination. The neighborhood is ninety-four percent non-Hispanic Black. It is a state-designated cancer cluster. Those who live there do not need a clinical trial to tell them that cancer is coming for their community. They need a way to find it before it’s too late.
The possibility is no longer theoretical. The NHS-Galleri study — the largest randomized controlled trial of multi- cancer early detection (MCED) ever conducted — demonstrated that a blood test can detect cancer at four times the rate of standard screening alone. Critically, it identified cancers at Stages I and II, when treatment is less invasive, less costly, and far more likely to succeed.
Read that again. A blood draw found deadly cancers years before symptoms would have driven patients to seek care. Across twelve of the deadliest cancers — including lung, pancreatic, ovarian, and colorectal — the test drove a substantial shift toward earlier diagnosis and more than a 20% reduction in Stage IV cases by the second and third years of screening. This matters profoundly, because 70% of cancer deaths come
from cancers for which no standard screeni...
