'Cancer' turns out to be fruit seed SEMINOLE HEIGHTS, Fla., April 27 (UPI) -- A Florida woman got some good news when she learned a dark spot on her lung was a seed that had been lodged there for almost 30 years. Blanca Riveron, 62, of Seminole Heights, was convinced she had lung cancer, WTSP-TV in St. Petersburg reported. Riveron said her daughter Melody, who lives in Cuba, reminded her on the telephone she inhaled a seed from a fruit called rispero in 1984. Riveron said she could not believe the seed would still be there after all that time. But she discovered the truth while sitting in a traffic jam when she had a bad coughing fit and the rispero seed came out. The seed also explains why she has suffered from a bad cough for decades that doctors diagnosed as asthma or pneumonia. Riveron's breathing has improved remarkably. She's even been able to blow up a balloon for my son. She had never been able to do that," another daughter, Dayana Noda, said.
