On May 1, 2023, an Oregon Health Sciences University (OHSU) dermatologist and a multi-disciplinary team confirmed that a tiny spot on Christy Staats’s cheek — measured just 0.65 millimeters or 0.025 inches — and almost invisible to the human eye confirmed the spot was indeed a melanoma, the most dangerous type of skin cancer.

Catching this skin cancer early earned the OHSU team the Guinness World Record for the ‘Smallest Detected Skin Cancer.’ The American Cancer Society estimated that in 2023, about 97,610 new melanomas will be diagnosed in the U.S.
