New Ultrasound Technique for Cancer Detection

In October, 2024, scientists announced a groundbreaking ultrasound technique that can detect cancers by transforming tissue into droplets, which are then released into the bloodstream for analysis.

Key Points

Innovative Detection Method: The technique, led by Roger Zemp from the University of Alberta, uses high-frequency ultrasound to dislodge small pieces of cancerous tissue, allowing the extraction of biomarkers like RNA, DNA, and proteins from the blood.
Potential to Replace Biopsies: This method aims to reduce reliance on traditional biopsies, which are often painful and invasive. The technique could help clinicians avoid nearly half of all biopsies needed for cancer diagnosis.
Cost Efficiency: The ultrasound method could bring the cost of cancer detection down significantly, estimating around $100 per test, compared to existing tests like the ‘CellSearch’ test, which costs about $10,000.
Broad Application Across Cancers: While the technique has been demonstrated in prostate cancer patients, researchers are exploring its effectiveness for other cancers, such as breast cancer and melanoma.
Need for Further Research: Experts emphasize the importance of conducting large-scale clinical trials to validate the technique's efficacy and sensitivity across different populations and cancer types.
Future Commercial Availability: If trials yield positive results, researchers may seek regulatory approval, potentially making this ultrasound-based detection method commercially available within five years.
