What if we could find cancerous tumors years before they can harm us -- without expensive screening facilities or even steady electricity? Physician, bioengineer and entrepreneur Sangeeta Bhatia leads a multidisciplinary lab that searches for novel ways to understand, diagnose and treat human disease. Her target: the two-thirds of deaths due to cancer that she says are fully preventable. With remarkable clarity, she breaks down complex nanoparticle science and shares her dream for a radical new cancer test that could save millions of lives.

Sangeeta Bhatia: This tiny particle could roam your body to find tumors

Miniaturization in medical tech could shift cancer screenings from costly facilities to a paper strip test, accessible globally.

A leap in cancer care: envisioning a future where tumor detection is swift, non-invasive, and ubiquitously available via nanotech.

Revolutionizing cancer detection, nanotechnology could soon diagnose tumors via a simple urine test, potentially saving millions.
