<s>[INST] Hello. Here is my question. I recently had a CT of chest with contrast. Findings: right upper lobe mass cented at approximately image #32 measuring l.2 x 0.9 x 2.4 cm in its cephalocaudad, AP and transverse dimensions. This mass corresponds with the noduar opacity seen on the chest x-ray. No other masses or suspicious lung nodules are identified. No significant hilar or mediastinal adenophathy. Impression: There is l.2 x 0.9 x 2.4 cm right upper lobe mass. I favor this representing a primary lung carcinoma rather than a metastasis. This X-ray and CT were ordered by my otolaryngologist who removed a cancer from my tongue 5 years ago and was doing a follow up. I have not seen a pulmonologist as yet. From this information above, can I tell what type or stage this lung carcinoma is? Thank you. Dolores [/INST] Thanks for your question on Chat Doctor. In your case It is very difficult to say whether this lung mass is primary or it is secondary due to spread from previous tongue cancer. But in my opinion it is secondary from tongue cancer only. And you should get done PET scan to rule out metastases in other organs too. If only lung nodule is there in PET scan than you can go for lobectomy of involved lobe. This will cure your nodule. </s>
