Those driving by the Mayo Clinic Health System Event Center and medical center the week of March 9-13 may wonder, “Why so blue?”

Both buildings will be lighted blue in recognition of Colorectal Cancer Awareness Month. As part of a campaign by the Colon Cancer Coalition and the Minnesota Cancer Alliance, dozens of landmarks and buildings across the state are going blue from dusk to dawn to bring attention to the nation’s second-leading cause of cancer death and the importance of routine screening.

Colon cancer screenings detect abnormalities within the colon, such as polyps or early-stage cancers.
