Wireless Pressure Sensor Relays Tumor Pressure

Interstitial pressure inside a tumor is often quite high compared to normal body tissue and may impede the delivery of chemotherapeutic agents as well as decrease the effectiveness of radiation therapy. Medications can temporarily decrease tumor pressure, but identifying the optimal time to initiate treatment, when tumor pressure is lowest, can be very difficult. Now, a team of scientists from Purdue University, West Lafayette, IN, has developed a unique sensor that can wirelessly relay pressure readings from inside a tumor.
