Four months after being hospitalized with a stroke, Lancaster Mayor John Howard has been diagnosed with lung cancer, city officials said Tuesday. He was admitted to Springs Memorial Hospital on Jan. 16 suffering from pneumonia, after dealing with a respiratory illness for the past few weeks, according to City Administrator Flip Hutfles. Doctors found a tumor in one of his lungs, and he was transferred to the intensive care unit at Carolinas Medical Center in Pineville last Thursday.
