Terahertz Laser Detects Skin Cancer

An electrical engineer at the University of Queensland has developed a prototype for a terahertz laser imaging system that can identify tumors in their early stages.

Transistors Hunt Cancer Cells to Reduce Surgeries for Cancer Patients

Tiny transistors can detect whether tumors have spread to other parts of the body, which could eliminate unnecessary surgeries for up to 40 percent of breast cancer patients. Typically, when surgeons operate to remove tumors, they take samples to see how far the cancer has spread. This analysis can take up to a week, and often requires follow up surgery. Now, tiny sensors can get the same results in less than an hour.
