AboutJuliet Seigle, MD Expertise I am a fully trained radiation oncologist and can answer many questions about cancer and its treatment. I can't answer questions about specific chemotherapy agents. I have also worked in general medicine and emergency medicine, so I can give advice about these areas as well. I would like to do this based on my very positive experience with one of your experts (real estate).
Experience I currently am working as a radiation oncologist in the DC metropolitan area. I have done research and given talks on neurooncology (tumors of the nervous system) at national meetings. I have been trained in use of a new technology, the CyberKnife. I was emergency physician at a busy communicty hospital (Calvert Memorial Hospital) in Maryland for 3 years (1989-1991).

Question I recently had a CT done for c/o abd. pain and it showed that I have a 2 mm non-calcified RLL pulmonary nodule. I am a 46 yr. old non-smoker. My PCP seems to think that it is from histoplasmosis although I have not been tested for this. He wants a CT f/u in 6 mos. Do I need to be concerned?
Answer Hi -
Small lung nodules are fairly common. A 2 mm lesion typically is too small to be biopsied (sampled and examined under the microscope). Your PCP's recommendation seems quite reasonable to me. If, on the next scan, it is larger, further imaging (for example, PET scanning) and biopsy would likely be indicated. If you are uncomfortable with this approach, the CT (which should be done with contrast) could be repeated in three rather than six months, or, you could seek an opinion from a lung specialist. However, I doubt that a lung specialist could pin down the diagnosis at this point in time.
