Groundbreaking study finds link between common bacteria and stomach cancer

A study led by NTU Singapore has found that Streptococcus anginosus bacteria play a significant role in causing stomach cancer. These bacteria, which are commonly found in the body, can lead to cell damage and changes that encourage gastric cancer, including inflammation and abnormal cell growth. The researchers also discovered that disrupting a protein on the bacteria’s surface impairs their ability to promote cancer. The findings, published in Cell, suggest that long-term S. anginosus infection can cause chronic gastritis and may collaborate with other pathogens to promote gastric cancer. Detecting S. anginosus in feces may help assess future cancer risk, highlighting the importance of good oral hygiene to prevent stomach cancer.
