ocregister.com on February 17, 2012 reported that a retired Orange doctor has surrendered his medical license, effective Friday, after he was accused of negligence that delayed a patient's diagnosis of lung cancer. Generoso Quimbo, who practiced until last year with St. Joseph Heritage Medical Group in Orange, agreed to settle the disciplinary charges brought by the California Medical Board. In legal documents filed in 2011, the board said Quimbo acted with repeated gross negligence in treating a patient who smoked. The documents say that the patient had an abnormal CT lung scan in 2006. Quimbo failed to follow up on the radiologist's recommendation that a tissue sample be taken of a lesion in the lung, according to the documents. In 2008, Quimbo ordered another lung scan after the patient came to him with complaints including blurred vision. By then, the mass had grown "significantly larger" and the patient was sent to an oncologist.
