Sources: 2. Developments: 2. Recent developments in medical biotechnology have introduced new methods for detecting cancer through blood samples. In October 2026, researchers from institutions in Russia and India developed a coin-sized chip designed to detect circulating tumor cells, specifically targeting breast cancer by utilizing folic acid receptors. Experimental tests showed the device detected between 80% and 91% of tumor cells without false positives, while keeping over 95% of captured cells intact for potential molecular research. By November 2026, further advancements in liquid biopsy technology were reported. Researchers at Tel Aviv University announced an optical DNA chip that identifies chemical fingerprints on DNA using a light scanner, reporting 93 per cent sensitivity for stages 2 to 4 diseases. This method is noted for its potential low cost and rapid turnaround time. Additionally, Illumina introduced an early access program for a sequencing workflow using duplex chemistry to detect trace amounts of circulating tumor DNA in plasma, aiming to study molecular residual disease and tumor evolution. ## Timeline ### 2026-11-08: Researchers develop new methods for cancer detection via blood tests New cancer detection methods are emerging, including an optical DNA chip from Tel Aviv University and Illumina’s new duplex sequencing workflow for studying molecular residual disease. 2 sources. https://clstr.news/cluster/researchers-develop-new-methods-for-cancer-detection-via-blood-tests ### 2026-10-09: Researchers develop chip to detect cancer cells in blood Scientists from Russia and India have developed a coin-sized chip that can detect circulating breast cancer cells in blood within 20 minutes with high accuracy. 3 sources. https://clstr.news/cluster/researchers-develop-chip-to-detect-cancer-cells-in-blood --- Cite as: Advancements in cancer detection technology.
