Hüsker Dü bassist Greg Norton has been diagnosed with cancer, the musician has disclosed on social media.“At the beginning of June, I was diagnosed with prostate cancer,” Norton wrote in a post on Facebook last Friday (July 1). “My doctors at the Mayo Clinic believe I have excellent odds, but we need to get in right away and move forward with treatment and surgery.”Norton went on to say that his band, UltraBomb, has cancelled planned tour dates in the UK and would be postponing North American dates, in order to allow him “time to recover and return in full force”.Friends of Norton have launched a GoFundMe campaign to assist with his medical costs.
