Stand-up comedian Alex Duong has sadly passed away. It's with heavy hearts we report that the beloved comedian, who notably appeared in the drama series Blue Bloods, has died at just 42 years old after a battle with cancer. Last year, Alex told the Los Angeles Times he had been diagnosed with alveolar rhabdomyosarcoma, a "rare soft tissue cancer," according to the Cleveland Clinic. Alex told the LA Times he developed a headache behind his eye early last year, followed by a bulge in his left eye that was so noticeable his boss sent him home from work.
