US EditionFlu, COVID may 'wake up' dormant cancer cells, new study finds
UNITED STATES, JUL 30 – Breast cancer survivors face a 44% to nearly twofold increased risk of lung metastases after respiratory infections due to inflammation-driven reactivation of dormant cancer cells, researchers found.
- Respiratory infections like COVID-19 and the flu may reactivate dormant breast cancer cells, increasing the risk of spreading in patients with a history of the disease.
- Patients who tested positive for SARS-CoV-2 had a twofold increase in cancer-related deaths compared to those who were negative.
- Patients with breast cancer who contracted COVID-19 were almost 50% more likely to experience metastatic progression to the lungs than those without a diagnosis of COVID-19.
- The findings indicate that cancer survivors may face increased risks of metastatic relapse after respiratory viral infections.

For Cancer Survivors, Respiratory Viruses Like Flu Or COVID Could Cause 'Sleeping' Cells To Wake Up
Common respiratory infections like the flu and COVID-19 might jolt dormant cancer cells back to life in survivors, causing them to multiply and spread in the lungs. The post For Cancer Survivors, Respiratory Viruses Like Flu Or COVID Could Cause ‘Sleeping’ Cells To Wake Up appeared first on Study Finds.
Cancer cells that have been dormant for years could awaken after flu or Covid infection, scientists warn
Scientists have discovered that common respiratory infections, including Covid and influenza, possess the ability to reactivate cancer cells lying dormant within the body, prompting their rapid dissemination.The infections can rouse what are known as disseminated cancer cells - malignant cells that have separated from original tumours and migrated to remote organs where they remain inactive, sometimes for years.The latest findings demonstrate ho…

COVID infection early in pandemic linked to higher risk of cancer death, study finds
Cancer survivors infected with COVID-19 in the early months of the pandemic had a higher risk of dying from dormant cells reawakening, Colorado researchers found, though they don’t know whether people who get the virus now face the same risk. Experiments in mice found that genetically modified animals were more likely to have signs of metastatic cancer in their lungs if infected with flu or COVID-19 than engineered mice that researchers didn’t g…

rd.nlCoronavirus and influenza infections may play a role in cancer recurrence in previously recovered patients. The viruses appear to be able to reactivate "dormant" breast cancer cells that have ended up in the lungs, at least in mice, international researchers report in Nature.
