Suggest Treatment For Idiopathic Pulmonary Fibrosis And Lung Tumor

My father is 80 and has recently been diagnosed with Idiopathic Pulmonary Fibrosis and a lung tumor. He is in relatively good health otherwise. He had a PET scan of the tumor and all of his other major organs. He also had a biopsy of the tumor. The biopsy showed that the 4 cm tumor is malignant (squamous). The tumor is located in the back lower part of his lung. The cancer is only in the lung tumor. He went to an Oncologist in Philadelphia (where he lives) today for a consultation. The Doctor said that a few things were not an option because of the IPF, including surgery and CyberKnife. The doctor said that CyberKnife was too risky because the lung moves at all times and the radiation could hit the fibrosis areas and cause damage. The Doctor recommended Chemo and has scheduled a 5 hour in-office treatment for next week. He said that if the tumor shrinks enough in a month, he would try to treat it with radiation. Otherwise, he would continue Chemo treatments for 6 months total. I don t like the idea of Chemo treatments for the next 6 months. I have a few questions: 1) Why is the doctor concerned about damaging the fibrosis areas of the lung with the CyberKnife radiation, but not with traditional radiation in a month? 2) Is chemo a good idea for an 80 year old man? 3) I read on-line that Georgetown University hospital has done a few thousand of the CyberKnife treatments on lung tumors, sometimes with other complications involved such as pluracy. Should we send his records to Georgetown U Hospital to get a second opinion and see if the doctors there think that the CyberKnife treatment can work? Thanks. - Dan
