my brother was diagnosed with papillomas in his throat when he was a baby. he is now 18 years old. he normally sees a doctor every 3 to 4 months to have it lasered out of his throat. lately he has been coughing up blood, and now he has to see the dr. every 4 weeks. the dr. said his condition is gerring worse. is papillomas deadly?, and are there any treatments for it?
