I am missing my left lung due to a cancerous tumor exactly 7 years ago. I do have some shortness of breath as a result. Four months ago I had a lumpectomy for a small cancerous lump in my left breast. I choose not to have radiation and am on Ameridex, can this cause a worsening of the shortness of breath? It seems that in the last few months I am becoming much more uncomfortable after slight distress, such as climbing stairs. Thanks.
Armies does not lead to any respiratory discomfort in most patients and is very well tolerated. The shortness is probably due to some abnormality in the remaining lung like an infection or spasm. You should consult a respiratory physician and get it checked out.
