Lung disease

Patient: I have pulmonary fibrosis and a recent cat scan indicated i have a mass on my lung and my doctor thinks its a 90% chance that it may be malignant. A biopsy has to be done ,but my risks are very high. Can radiation be done without a biopsy? And, instead of a biopsy can nodes be removed and tested to see if the mass is malignant? They have said I might not make it through the biopsy as my lungs may collapse due to my pulmonary fibrosis condition. Is there any other way out of this for me? Please help.
