Johns Hopkins blood test detects tumor dna three years early
- Researchers at Johns Hopkins discovered that tumor DNA fragments can be detected in blood up to three years before cancer diagnosis as of June 13, 2025.
- This discovery resulted from examining blood plasma collected from symptom-free participants in a large NIH-supported cardiovascular health study known as ARIC.
- The study showed eight people scored positive on a multicancer early detection test, with tumor mutations confirmed years before clinical diagnosis.
- Yuxuan Wang highlighted that detecting cancer mutations well in advance allows opportunities for earlier treatment, while Bert Vogelstein emphasized that the study establishes key sensitivity standards for effective early cancer detection tests.
- This breakthrough suggests earlier diagnosis may increase treatment options and cure rates, but appropriate clinical follow-up after positive tests remains to be defined.

Johns Hopkins blood test detects tumor dna three years early
Researchers at Johns Hopkins found that fragments of tumor DNA can appear in the bloodstream up to three years before a cancer diagnosis, offering a potentially revolutionary window for early detection and treatment.
Researchers at Johns Hopkins University identified genetic fragments associated with blood tests collected over three years before the official diagnosis of cancer, according to a study.
Liquid biopsy, which utilizes markers released by cancer cells into the bloodstream, can reveal potential cancer recurrence and residual disease after cancer treatments long before traditional methods. The method has also been introduced in Finland. Cancer treatment is constantly becoming more individualized. The greatest strides towards personalized treatment have been taken in recent years, especially through the development of gene and molecu…
