"Revolutionary $5 Spit Test Detects Breast Cancer in 5 Seconds"

Researchers in Florida and Taiwan have developed a portable spit test that can detect breast cancer using a single drop of saliva in just five seconds, costing only $5. The palm-sized handheld device uses common components like glucose tests and open-source hardware to analyze cancer biomarkers in saliva, providing a low-cost alternative to invasive procedures like mammograms and ultrasounds. The test has shown promising results in differentiating between healthy individuals and those with breast cancer, but it may take several years to be available to patients pending regulatory approval.
