March is National Colon Cancer Awareness Month, a time to spread the word about detection. Last week’s Park Theater concert with Faithfully, a Journey tribute band, turned into a rally for education when lead singer John Allen announced he was recently diagnosed with stage three colon cancer and had undergone surgery just 10 days prior to the concert.“I didn’t know if I would mention it or not,” said Allen of his diagnosis. “This is Colon Cancer Awareness Month so let’s raise some awareness and maybe save a life.”Allen said he has no family history of colon cancer, doesn’t smoke, eats relatively healthy and is 47 years old.
