<p data-start="24" data-end="235"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">A team of researchers from Israel and the United States has developed a simple blood test capable of detecting the risk of developing leukemia&mdash;one of the most dangerous blood cancers&mdash;well before symptoms appear.</span></p>
<p data-start="237" data-end="413"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Published in <em data-start="250" data-end="267">Nature Medicine</em>, the study presents this blood test as a potential alternative to the currently used bone marrow biopsy, an invasive and often painful procedure.</span></p>
<p data-start="415" data-end="732"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">The researchers, led by the Weizmann Institute of Science in Israel, focused their efforts on understanding myelodysplastic syndrome (MDS), a condition that affects how blood-forming stem cells mature. MDS often results in severe anemia and can evolve into acute myeloid leukemia, a common type of adult blood cancer.</span></p>
<p data-start="734" data-end="1053"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Instead of relying on bone marrow samples, the team found that rare stem cells&mdash;which occasionally escape the bone marrow and enter the bloodstream&mdash;hold crucial early indicators of MDS. By using advanced single-cell genetic sequencing, they were able to extract and analyze these rare cells from a standard blood sample.</span></p>
<p data-start="1055" data-end="1345"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Remarkably, these circulating stem cells also function as a biological "clock," providing clues about an individual&rsquo;s chronological aging. The study found that these stem cell changes occur earlier in men than in women, possibly explaining the higher incidence of blood cancers among males.</span></p>
<p data-start="1347" data-end="1501"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Dr. Nili Furer of the Weizmann Institute noted that this gender-based difference in stem cell aging may contribute to the increased risk of cancer in men.</span></p>
<p data-start="1503" data-end="1756" data-is-last-node="" data-is-only-node=""><span style="font-family: georgia, palatino, serif; font-size: 12pt;">The researchers believe this breakthrough could not only enable early detection of leukemia but also help identify other age-related blood disorders. The test is currently undergoing large-scale clinical trials across multiple medical centers worldwide.</span><br><br><span style="font-family: georgia, palatino, serif; font-size: 12pt;">[Except for the headline, this article has not been edited by the Benefit News editorial team and is published directly from the IANS news feed]</span></p>
