firefighter with two nodules

[fireangel]

Hi.. I have been a volunteer firefighter for about five years and exposed to many wildland fires as well as a few structure fires. I was recently diagnosed with two nodules: 3mm nodule in left lower lobe and 4mm pleural based right middle lobe nodule. No effusion or consolidation. Heavily calcified subcarinal right hilar lymph nodes without adenopathy. Calcified granulomata in spleen. The findings were that I had prior granulomatous infection with non specific pulmonary nodules.
These were found on a ct in the er where I was recently treated for tachycardia and left chest tightness. No cause was found except for dehydration caused by 2 monthes loose stools. Ekg is fine.My blood tests came back with elevated CBC's (they are rechecking this), low calcium, very low lymphocytes and other abnormalties inc high d-dimmer. Stool samples came back negative for any kind of infection, thyroid is fine. I am routinely checked for hiv, tb, and hep with the fire dept.  Last year I had a hysterectemy that required blood transfusions. The last couple of years I have had asthma like symptoms. Allergists says it's asthma and havfever, drs say it's probably just hayfever. I've had pneumonia and broncitus a few times in my life as well as mono years ago. My granpa just died of lung cancer.. he had quit smoking 25 years before they found it.
My question is this: Should I be concerned? I think so but they are only following up with a cat scan in a year because I requested it... Is this too long? Is it time for a second opinion? They are still investigating the blood work but not worried at all about the nodules.

These are very small nodules and very likely to be the result of a prior granulomatous infection.  Unless you also have major risk factors for cancer, you should not be concerned.  It would be reasonable to wait 6 to 12 months to repeat the CT scan.  Further investigation of the blood is certainly appropriate.  Keep in mind, the D-dimer value may be falsely elevated.
