呼吸道感染竟会唤醒“体内的敌人”

Core Insights - Respiratory infections, such as influenza, may activate dormant cancer cells, potentially leading to cancer metastasis [1][2] - A study conducted on mice showed that respiratory infections can trigger the awakening and proliferation of dormant breast cancer cells, leading to significant tumor growth within two weeks [2] - Analysis of human data revealed that cancer patients who experienced respiratory infections had double the risk of cancer-related mortality, with breast cancer patients facing over a 40% increased risk of lung metastasis post-infection [2] Group 1 - The study published in Nature highlights the potential link between respiratory infections and the reactivation of dormant cancer cells [1] - Dormant cancer cells can remain in a state of inactivity, but respiratory infections may serve as a catalyst for their reactivation [2] - The immune response to infections may inadvertently create a favorable environment for cancer cells to thrive [2] Group 2 - The research emphasizes the importance of preventing respiratory infections, especially for cancer survivors [3] - Simple preventive measures such as wearing masks, getting vaccinated, and practicing good hygiene can help reduce the risk of infections [3] - The findings call for further research to expand sample sizes and deepen analysis on the relationship between respiratory infections and cancer [3]
