Wireless sensor transmits tumour pressure

The interstitial pressure inside a tumour 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 radiotherapy. While medications exist that temporarily decrease tumour pressure, identifying the optimal window to initiate treatment — when tumour pressure is lowest —remains a challenge. Researchers at Purdue University have developed a novel sensor that can wirelessly relay pressure readings from inside a tumour.
