Hi and thank you so much for this query. I am so sorry to hear about this. A fibrocystic disease really has no potential of becoming cancerous in future. I would not think you should be particularly concerned ore than any other person in the general population who is going in for this test. I wish you the best of possible outcomes. Just be relaxed and let s see what we get. I hope this addresses your query fully. Feel free to ask for clarifications and more information if need be. I wish you well. Thanks for utilizing our services, we very much appreciate it. Dr. Ditah, MD.
