Researchers led by UC San Diego develop a non-invasive blood test capable of detecting circulating tumor DNA methylation to identify whether a person has one of the five most prevalent forms of cancers, up to four years before diagnosis. The team states their diagnostic can detect cancer by targeting a limited number of genomic regions aberrantly methylated across different cancer types, allowing it to be used as an inexpensive cancer screen from only a single vial of blood, unlike the more costly ctDNA which works by identifying a legion of inconsistent mutations.

Non-invasive blood test can detect cancer four years before diagnosis.

The leading cause of death worldwide, cancer killed at least 7.6 million people in 2008, accounting for a staggering thirteen percent of all deaths globally. With no signs of abating, … Continue Reading Non-invasive blood test can detect cancer four years before diagnosis.

Researchers use non-invasive ‘diagnostic pill’ to detect breast cancer in mice.

Unchanged for decades, breast screening technology such as mammograms can be painful and generally rely on anatomical differences with several limitations.  These include the lack of phenotyping to identify aggressive … Continue Reading Researchers use non-invasive ‘diagnostic pill’ to detect breast cancer in mice.

Noninvasive eye scan can detect key signs of Alzheimer’s Disease in humans.

Alzheimer’s disease (AD) is a fatal neurodegenerative disorder as well as the leading cause of senile dementia worldwide, with no effective treatment and limited functionality for early diagnosis.  Now, a … Continue Reading Noninvasive eye scan can detect key signs of Alzheimer’s Disease in humans.

New nanotech contrast enables blood test for precancerous growth in colon cancer.

Colon cancer is often detected in its earliest stages thanks in part to screening technologies like colonoscopy. By snaking a camera through a patient’s intestines, doctors can identify polyps and … Continue Reading New nanotech contrast enables blood test for precancerous growth in colon cancer.
