Dr. Nagourney Featured on TEDx Talk

Dr. Robert Nagourney has worked 20+ years refining a laboratory technique that measures how cancer cells respond when they are exposed to drugs and drug combinations.

Listen as he shares his insight into cancer, cancer research, and his treatment philosophy in this TEDx Talk. 

The Science

Functional Profiling is the Key

With our functional profiling test, we can help discover the most effective and least toxic drug regimen for you PRIOR to initiating treatment.

We expose your  living cancer cells in the laboratory to chemotherapy drugs, targeted agents and combinations.

By using therapies found active in the laboratory, Dr. Nagourney has been able to double response rates and improve survival for his patients.

Results are generally available within 7 days of receipt of your cancer sample in our laboratory.
