Hi I was told I had a 7 mm nodule at the time that they found it after i complained of chest pain via coughing. I went to the GO, Pulmonary and they said it was small that it was not worth extracting. That it will get smaller in time. So my ques5is do I myself ask for a cancer screening test for my lungs? Neither doctor's said anything Abt that? Also the cough has come back I did also have a blood clot that came through on August of last year which I was shocked. That went away. But now that this cough comes up sporadically as well as my wbc and platelets are low. Need advice here. Thank you.
