Freenome, the Roche-backed early cancer detection liquid biopsy developer has raised yet more money, making it one of the best-funded companies in its sub-sector. With trial results due relatively soon, investors are likely hoping this will be the last funding round required before full commercialization.

Sergey Young is on a mission to "extend healthy lifespans" by investing in longevity breakthroughs. Last year, the venture capitalist established a $100m fund investing in technologies with the potential to improve healthy long living.

With Freenome recently scoring $160m in new financing, the San Francisco-based start-up is poised to ramp up development of its cancer-detection platform. Medtech Insight hears from the firm's CEO and co-founder, Gabe Otte, about the company's next steps.

Liquid biopsy is a rapidly developing noninvasive technology for the early detection of cancer. Multiple companies have entered clinical testing, using mostly blood to detect circulating tumor cells and/or circulating tumor DNA. But urine and even cerebral spinal fluid are promising liquids too. Regardless of the fluid, testing costs a fraction of a traditional, invasive tissue biopsy and offers much quicker results.
