Who we are

Preferred Medicine is committed to addressing the issues that today’s cancer screening options may not provide the best early detection results, leading to invasive biopsies and unnecessary stress for patients. As a precision oncology company that combines the power of miRNA and AI technologies, Preferred Medicine provides a simple and highly accurate blood test to detect the world’s most common cancers at an early stage.

Our goal is to widen access to cancer screening for all at risk patients - helping to reduce uncertainty and healthcare costs, while improving care, quality of life, and in many cases, saving lives.
