question: MY DAUGHTER is 22 y.o. and had classical Hodgkin lymphoma. She just had a biopsy of the mediastinum area over a week ago and before that had a mild dry cough, it seems that she has been experiencing some shortness of breath upon exertion and yesterday she had a CT scan of the upper chest with contrast and she said last night when she was going up steps she got short of breath with almost a slight dizziness.
