Imagine fighting cancer only to learn the medicine might help it spread. A July study from Tsinghua University exposed mice to doxorubicin, cyclophosphamide, or cisplatin and saw lung tumors bloom far faster than in untreated animals. The drugs drove nearby fibroblasts into senescence, stripping them of lamin B1 and flooding tissue with growth proteins that awakened dormant cancer cells. Metastases doubled, creating what scientists call a fertile ground for invasion. Researchers stress that chemotherapy still saves lives but urge swift trials pairing it with senolytic or immune therapies to blunt this risk. Patients should not stop treatment, yet the findings signal a critical need for personalized cancer care. Disclaimer: This news is shared for journalistic and informational purposes only.
