9-year-old Maria Lugo came to Arcadia Arcadia Methodist Hospital from Mexico to have a steel plate removed from her chin. It was a follow-up surgery to a softball-size tumor removal she had in April, 2008, at Arcadia Methodist Hospital. Dr. Jon Tyrell, a member of LIGA International, and Dr. B.S. Chandrasekhar operated on her. LIGA International is a non-profit group of medical experts, pilots and volunteers who travel to clinics in Sinaloa, Mexico several times a year.
