Researchers have developed a noninvasive brush test that can detect oral cancer in just one hour, offering a faster and less painful alternative to traditional scalpel biopsies. In a study involving more than 1,000 samples, the test accurately identified oral cancer while potentially eliminating over 90% of unnecessary invasive biopsies. Because the test uses a simple brush swab, it can also be repeated regularly to monitor high-risk patients and detect cancer earlier. Although further clinical implementation is needed, this breakthrough could improve early diagnosis, reduce patient discomfort, and increase survival by identifying oral cancer before it reaches advanced stages.
