In a development hailed as a major step forward in cancer prevention, scientists have introduced a blood-based screening tool capable of detecting more than a dozen cancers at their earliest and most treatable stages.

The test combines genomic sequencing with AI-assisted pattern recognition, achieving up to 92 percent accuracy in early trials across 11 countries. Researchers believe the technology could reach clinical use within three years.

“Early detection is the closest thing we have to a cure for most cancers.”

The screening works by identifying microscopic DNA fragments shed by tumors into the bloodstream. AI models analyze mutation patterns invisible to traditional diagnostic methods, allowing for detection before symptoms appear.

AI-assisted mutation tracking allows for earlier and more accurate screening.

If validated in larger clinical trials, the test could shift cancer care from late-stage treatment to early intervention, where survival rates are dramatically higher. Insurers and public health agencies have already expressed interest in supporting widespread screenings.

“We are on the verge of a paradigm shift,” said Dr. Victor Ramirez, a senior oncologist involved in the research. “This could rival the impact of the first chemotherapy treatments introduced decades ago.”
