Study Reveals Cancer-Like Cells in Healthy Breast Tissue
A study by The University of Texas MD Anderson Cancer Center reveals that some normal breast cells in healthy women exhibit chromosome abnormalities typically linked to invasive breast cancer. Published in Nature, the research found that at least 3% of normal breast cells in 49 healthy women showed aneuploidy, challenging traditional views on breast cancer's genetic origins and potentially affecting early detection methods. The study highlights the risk of false positives in cancer diagnostics and suggests that these cellular changes increase with age, raising questions about when cancer actually begins.
