7 yr s of unexpland body pain rashes misscarraiges fatigue lung nodules. Now for 6 mos strait hip shoulder + chest pain. And a + ANA lab. Lupus?

Maybe: Lupus is a complex autoimmune disease in which the body is attacking its own tissue. Lupus is famous for affecting different people in different ways. The effects can be so different from person to person that it does not even look like they have the same diagnosis. ANA is only a screening test that tells us more tests are needed. See a rheumatologist!

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

In 72'-74', I was on a U.S Navy ship, which was full of asbestos. In 05', I was diagnosed with that left lung nodule. May this have caused my nodule?

You're still alive: If the nodule was found ten years ago, and you had no illness as a result, then this is not cancer. If it were cancer, you might have a pretty good case. I'm glad it's not. Asbestosis itself presents as diffuse thickening of the lung texture, or of the pleural surfaces. Most lung nodules in non-smokers (hope that's you) are old histoplasmosis, which is harmless. Thanks for your service.

Many types of tumor: If a lung lesion was noted as solitary and no previous history of underlying disease with bx of mesothelioma then Asbestos has been associated with such lung lesions. Squamous Ca usually derived from smoking and adenoCa from a viral source. At this time worth while to get PET/CAT to assure all path absent from lung or metastatic foci.

Lung nodules 7 mm are they a concern?

Lung nodules 7 mm are they a concern?

It depends: Not all lung nodules are alike. The odds that a nodule is cancer depends in the appearance and size of the nodule, the medical history of the patient, the smoking history of the patient, and how the nodule changes over time. Radiologists, pulmonary physicians and thoracic surgeons are best qualified to determine the risk that a particular nodule is cancer.

If a person smoked, does that cause cancerous lung nodules?

Modules: Smoking increases the risk of developing cancerous lesions. But not every nodule in current or past smokers is cancerous. Every nodule must however be considered cancer until it has been appropriately monitored or biopsied to rule out cancer.

Lung nodule grew 6mm, could I have cancer?

Lung nodule grew 6mm, could I have cancer?

50%: A non calcified lung nodule has a 50%risk of being cancer. Diagnosis of cancer is made by pathologist on a microscopic slide of a significant biopsy size. Removal of the whole nodule provides the pathologist with adecuate specimen. Needle biopsy of a lung cancer will miss the diagnosis half the time. So if it is cancer by needle bx it is. Otherwise undiagnostic.

Will a 6mm lung nodule show up on a pet scan?

Will a 6mm lung nodule show up on a pet scan?

Maybe: Lung nodules smaller than 10 mm (3/8 inch) can be falsely negative on pet because of limitations of the technology. That means the uptake on the scan is not high enough to be suspicious even though the nodule is actually worrisome. However, some small nodules have enough uptake despite their small size. The pet is not a bad idea for a 6 mm nodule, and if positive, means aggressive evaluation.

I was wondering does mold cause lung nodules?

I was wondering does mold cause lung nodules?

Yes: Agree certain inhaled substances, including fungi can result in nodule development. All lung nodules require follow up and potentially more investigation based on history, findings, and criteria.

Can a biopsy be taken of a calcified lung nodule?

Can a biopsy be taken of a calcified lung nodule?

Yes, but: Calcification of a lung nodule frequently indicates that it is benign in nature. It is the noncalcified nodules that are most concerning for lung cancer. And thus the noncalcified nodules that more frequently meet criteria that prompts biopsy of the nodule. Appropriate treatment of lung nodules is best done at facilities with experience

Ir lung nodules are not cancer, what exactly are they?

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.

Could aspirating a small piece of popcorn cause a lung nodule?

Yes: Inhalation of foreign bodies will initiate an inflammatory response from your immune system which can ultimately culminate in a calcified lung nodule on x-ray.

Wanted to know if benign lung nodules can cause asthmatic symptoms?

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

My father was diagnosed with lung nodule. Should I be worried for him?

My father was diagnosed with lung nodule. Should I be worried for him?

Needs investigation: Lung nodule needs to be investigated to ascertain the underlying pathology. It may a residua of an old infection, an easily treatable infection or lung cancer. Worrying would not address the issue. Your father should see an internist or a pulmonary specialist.

I was wondering what are the odds that a 2cmx3cm lung nodule is cancer?

Tissue biopsy: At least 50% if non smoker over that if smoker. Need to perform excisional or incisional biopsy and cultures for the pathologist to determine what is it.

Can a radiologist tell if a lung nodule is benign by just looking at it?

Can a radiologist tell if a lung nodule is benign by just looking at it?

Often but not perfec: Often there are certain characteristics on the xray that are helpful but no guarantee. It is often helpful to obtain a pet/ct scan as it has more accuracy. The best test is a biopsy if possible.

What is the difference between lung nodule on pleural surface vs subpleural?

What is the difference between lung nodule on pleural surface vs subpleural?

Pleural/subpleural: A pleura is a serous membrane which folds back onto itself to form a two-layered membrane structure. The thin space between the two pleural layers is known as the pleural cavity and normally contains a small amount of pleural fluid. The outer pleura (parietal pleura) is attached to the chest wall. The inner pleura (visceral pleura) covers the lungs and adjoining structures. The subpleura is below it

How long can a person with a 1.4 lung nodule live with and without treatment?

How long can a person with a 1.4 lung nodule live with and without treatment?

Depends: Depends on what caused the lung nodule. Even among cancers, there are different types with different prognosis. If it is lung cancer and you don't treat it, generally you will die from it but your life expectancy may vary greatly depending on the type and spread - from months to 5+ years. If it has not spread and you take it out, you have a good chance of being cured.
