Hi,

Thanks for posting the query on XXXXXXX

After going through your query, I would like to comment the following:

1. You do not seem to have any symptom at present.

2. Sub-centimetric nodules in the left lower lobe seem to have been detected on ct thorax.

3. I would like to inform you that, fewer than 1% of very small (<5-mm) nodules in patients without a history of cancer are malignant. Thus 99 % of such nodules are not malignant.

4. If no risk factors for malignancy are present (like smoking), then the nodule need to be observed for 12 months and a CT thorax plain and contrast be repeated at 12 months. If the nodule has remained unchanged then no further follow up.

5. PET (Positron emission tomography) is an optional alternative.

6. FNAC or biopsy from such small lesions is very difficult.

Thus in absence of any clinical features or risk factors, observation is the best strategy.

I hope I have answered your query. I will be glad to answer follow up queries if any.
Please accept my answer if you have no follow up queries.

If something like this could become malignant is it good that it can be caught early to be resected or cut out?

Hi XXXXXXX
Thanks for the follow up.

Ideally it is not recommended to go under the knife without confirmation of diagnosis. Also post resection there will be significant respiratory impairement. So the recommended approach is careful observation atleast for a year, and may be a PET scan.

I hope I have answered your query. I will be glad to answer follow up queries if any.

Hi,

Thanks again for follow up.

It is difficult to say the duration of these nodules since you had no symptoms, however there is a possibility of some past healed infection resulting in these nodules.
The growth and origin of these can be commented only after an observation for a period of at least 1 year.
However from the clinical picture given so far , it seems to be a benign lesion.

I hope I have answered your query. I will be glad to answer follow up queries if any.
Please accept my answer if you have no follow up queries.
