[|Human|] I recently had a routine chest xray that showed "indeterminate density in upper chest (right lung base)" I have smoked in the past, but never a heavy smoker. I have no symptoms. The xray was part of a normal physical. I am 48 years old and female.No lung cancer in the family, although Dad had prostrate cancer at 55 (he is 85 now) and Mom died of breat cancer at 79.Doctor order a CT scan with contrast. I have to get blood work for contrast, and then the CT scan.What are the chances of cancer? What could be other causes of the density?
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. Upper lobe indeterminate opacities can be due to following causes.1. Tuberculosis (fresh lesions)2. Old healed scar3. Pneumonia4. Sarcoidosis5. Lung cancerSince you were smoker, possibility of infection and lung cancer is high. So better to consult pulmonologist and get done1. CT thorax2. Bronchoscopy and BAD (Bronchoalveolar lavage) analysis. Treatment of these diseases are different, so better to first diagnose yourself and then start appropriate treatment. So consult pulmonologist and discuss all these possible causes.
