Cancer is one of the leading causes of death in first-world countries. While not every type of cancer can be cured, however, spotting it early can help patients get the treatment they need. That’s something researchers from ETH Zurich in Switzerland think they may be able to assist with — courtesy of a smart new biomedical “tattoo” that is able to detect 40 percent of cancer types, including colon, breast and prostate cancer. Its creators claim that the tattoo, which looks like a beauty spot, is able to identify these cancers at an early non-symptomatic stage while they have a cure rate of more than 90 percent.
