Wireless sensor transmits tumor pressure

The interstitial pressure inside a tumor is often remarkably high compared to normal tissues and is thought to impede the delivery of chemotherapeutic agents as well as decrease the effectiveness of radiation therapy. While medications exist that temporarily decrease tumor pressure, identifying the optimal window to initiate treatment—when tumor pressure is lowest—remains a challenge. With support from NIBIB, researchers at Purdue University have developed a novel sensor that can wirelessly relay pressure readings from inside a tumor.
