Warwick University scientists create diamond-based sensor for cancer tumour detection:

Researchers at Warwick University have developed a handheld, diamond-based magnetic field sensor capable of tracing magnetic fluid injected into the human body. Reported in Physical Review Applied, this non-toxic and non-radioactive device offers a safer and less invasive alternative to current radioactive techniques used for tumour detection, particularly in diagnosing metastasised breast cancer. By harnessing the unique quantum properties of diamond, the innovation could mark a breakthrough in cancer diagnostics.
