Russian Scientists Develop Blood
Test for Early Breast Cancer Detection
Moscow, 15 Oct 2026 (ONA) — Scientists
at Russia’s Sechenov Medical University have developed an effective blood test
that aids in the early detection of breast cancer with high sensitivity.
According to the university’s
experts, the study involved 135 women, 55 of whom were diagnosed with breast
cancer, after measuring the concentrations of five blood proteins: osteopontin,
soluble VEGFR2, neuropilin-1, suPAR, and tenascin-C—proteins associated with
inflammation, new blood vessel formation, and tumor growth.
The tests demonstrated the system’s
ability to detect 96.4 percent of cases, though false positives were recorded
among some healthy women. Osteopontin emerged as the most significant marker,
given its association with inflammation and the spread of cancer cells. Scientists
are examining the possibility of targeting it to develop new anti-cancer drugs.
Researchers believe the test could
in the future help identify women most in need of additional screening for the
disease, stressing that the method has been tested on a small sample of people
and therefore cannot currently replace mammography.
