Given the situation, a team of scientists from the University of Florida and the Yang Ming Chiau Tung National University They have managed to design a prototype with which it will be possible to detect indicators of breast cancer with just one saliva sample and without being so expensive. However, it should be noted that, so far, it has only been applied to 21 people and more studies are needed to prove its effectiveness.

What is the new test for detecting breast cancer?
“Our device is an excellent option because it is portable (about the size of a hand) and reusable,” said Hsiao-Hsuan Wan, a chemical engineer and lead author of the study published in the Journal of Vacuum Science and Technology, in which the device is announced.
The innovative test uses paper test strips treated with antibodies that interact with specific cancer biomarkers. The design is considered a revolution compared to more traditional alternatives such as mammograms, ultrasounds and MRIs.

How much does a saliva test for breast cancer cost?
Advanced technology is often used to detect cancer, but it is not always accessible, especially for people with low incomes. Wan says the new method is less expensive than traditional tests.
“Our technology is more cost-effective: the test strip costs just a few cents and the reusable circuit board is priced at five dollars. We are excited about the potential to make a significant impact in areas where people may not have had the resources for breast cancer screening before,” the scientist said in an official statement.
How does the device for detecting breast cancer with saliva work?
According to an article in the Journal of vacoom science and tecnology BThe test works by using a small sample of saliva on a test strip treated with antibodies that react to biomarkers.
The saliva particle sends pulses of electricity to the electrical contact points on the biosensor device. The pulses cause the biomarkers to bind to the antibodies and alter the charge. This produces a change in the output signal that can be measured and translated into digital information about the amount of biomarker present.
How to prevent breast cancer?
To prevent breast cancer, it is important to avoid cancer risk factors, according to the National Cancer Institute (NCI). These include smoking, being overweight and lack of exercise.
In addition, it is recommended that women over 20 years of age undergo periodic tests“A 30-year-old woman has a 1 in 200 chance of being diagnosed with breast cancer in the next 10 years, while a 70-year-old woman has a 1 in 25 chance,” the center said in an article.
The Spanish Society of Medical Radiography speaks out
Following the news of the innovative test to detect cancer using saliva, the Spanish Society of Medical Radiography issued a statement warning that there is no scientific evidence capable of confirming the presence of cancer with only fluid biomarkers. “The only tool for early diagnosis of breast cancer in women with a population risk of breast cancer is mammography,” said the specialized entity.
