Angela and Marions, Thank you so much for your replies. I was also thinking it could be some allergy, but with the recent diagnosis of CC in my father we do not know much about what happens in course of time. We have also started on a cough suppresant. Lets see how my father responds to it.
My father is suffering from cholangiocarcinoma. And since the past 2 days, he suddenly started coughing a lot. He is having dry cough without any mucus. What could be the reason for this? – Rosy
