With the help of these symptoms, you can detect breast cancer yourself – Dainik Savera Times

Florida: Scientists have developed a saliva test that detects breast cancer and has shown promising results in preclinical testing. A new handheld gadget detects breast cancer indicators from a small sample of spit, according to researchers at the University of Florida and National Yang Ming Chiao Tung University in Taiwan. Their findings were published in the Journal of Vacuum Science and Technology B.

“Imagine medical staff doing breast cancer screening in communities or hospitals,” said Hsiao-Hsuan Wan, a UF doctoral student in the department of chemical engineering and lead author of the study. “Our device is an excellent choice because it is portable – about the size of your hand – and reusable. “Test time is less than five seconds per sample, making it highly efficient.”

The new device works by placing a saliva sample on a test strip, which is treated with specific antibodies that react to cancer biomarkers. Electrical impulses are sent to contact points on the biosensor device. The signals are measured and translated into digital information about how much of the biomarker is present. The results are quick and easy to understand, Wan said.

During testing, the device distinguished between healthy breast tissue, early breast cancer, and advanced breast cancer in a small group of 21 women. Their biosensor design uses common components such as glucose test strips and the open-source hardware-software platform Arduino.
