Do severe viral infections increase lung cancer risk?

重度のウイルス感染症は肺がんのリスクを高めるのでしょうか?

New research suggests that severe respiratory infections, such as COVID-19 or influenza requiring hospitalization, may increase the long-term risk of lung cancer.

新しい研究によると、COVID-19やインフルエンザなどの入院を必要とする重症の呼吸器感染症は、肺がんの長期的なリスクを高める可能性があります。

This phenomenon is linked to "post-viral inflammatory memory," where the body's immune response causes lasting changes in lung tissue.

この現象は「ウイルス感染後の炎症性記憶」と関連しており、体の免疫反応が肺組織に永続的な変化を引き起こします。

Specifically, it triggers the accumulation of pro-tumor immune cells and alters lung epithelial cells, leaving them in a vulnerable state for months or years.

具体的には、腫瘍促進性の免疫細胞の蓄積を誘発し、肺上皮細胞を変化させることで、数ヶ月から数年にわたって脆弱な状態に置かれます。

Studies have even noted a potential 24% increase in lung cancer diagnoses among those previously hospitalized for severe COVID-19, regardless of smoking history.

研究では、喫煙歴に関係なく、重症のCOVID-19で以前に入院した患者において、肺がんの診断が最大24%増加する可能性が指摘されています。

Vaccination plays a critical role by training the immune system to fight viruses effectively, thereby preventing the severe illness that leads to this harmful "immune scarring."

ワクチン接種は、免疫系を訓練してウイルスと効果的に戦えるようにし、有害な「免疫の瘢痕化」を引き起こす重症の疾患を予防する上で重要な役割を果たします。

For those who have recovered from severe pneumonia, doctors recommend closer monitoring and potentially earlier cancer screenings.

重症の肺炎から回復した人には、医師はより綿密な経過観察と、より早期の癌検診を勧めています。
