Q: lung nodule grew 6mm, could i have cancer?

Yes: Yes, it could be lung cancer or it could be something else. Risk factors, overall size, growth rate, radiographic characteristics all play a role in diagnostic suspicion. You should discuss with your thoracic surgeon. 6mm plus what baseline would help in ability to biopsy.

Q: i was wondering does mold cause lung nodules?

Yes: Fungal lung infections commonly will result in nodular lesions to a greater or lesser extent. These will frequently remain in the lungs after an infection and cause concern for cancer until they develop calcifications which are rarely seen with cancerous nodules in the lung. Ct of the lungs is very sensitive for calcification and is frequently used for evaluation of pulmonary nodules.

Q: will a 6mm lung nodule show up on a pet scan?

Borderline to nope: It would be seen on the ct component of the scan but may not uptake enough FDG to make it light up. Many centers use 8 mm as cutoff but i guess it will vary a bit from place to place. I would not call such nodule negative if it did not light up on pet.

Q: what is the treatment for a 6 mms lung nodule?

: Treatment ? That would depend on what it is from. Such a tiny nodule could be a simple normal lymph node needing nothing or a part of a disease. The treating physician would explore what it is from before deciding what if anything needs to be done. They might just watch it for a while.

Q: can a biopsy be taken of a calcified lung nodule?

Yes: Open is best, needle will not get good or complete info. But most are benign and if tracked with imaging will not need biopsy.

Q: what are the odds that a lung nodule is cancer?

It depends: The size and characteristics are important indicators of whether a nodule is cancerous. Previous chest x-rays or scans would also be helpful. If the nodule is a new nodule (not seen on previous films) and the person is a smoker, it is more likely to be cancer than if the nodule has been seen and has remained stable over time.

Q: can lung nodules be caused by exposure to asbestos?

Unlikely: Lung nodules tend to be the result of either infectious processes or tumors (benign or malignant). Asbestos exposure usually results in calcificiation along the lining of the lungs (called pleural plaques) or scarring of the lungs (called asbestosis).

Q: ir lung nodules are not cancer, what exactly are they?

Many things: Some are from trapped tissues from old infections such as pneumonia, some are old granuloma or set in inflammation that has died down (like a chalazion in the eyelids, or old scars.

Q: wanted to know if benign lung nodules can cause asthmatic symptoms?

No: Asthmatic symnptoms are a response of the trachobronchial treee to an allergic response and is treated as such. Benign lung nodules are unrelated to any secondary allegric or IgG response

Question 1

can small lung nodules be cancerous?

Accepted Answer

Rarely: In people without history of cancer, 5 mm or less in diameter lung nodules have a <1%  chance of being malignant.  Lung nodules are generally followed on ct scan for 2 years to be sure they do not grow in size.  Those that grow can be biopsied by ct guidance, bronchoscopy, or surgery. Check for other causes (exposure to tb,  rheumotologic).
