10 yr bc survivor. Cxr showed a solid nodule in lung, or in chest wall. What's the difference of lung and chest wall? Scar tissue fm mastectomy?

Need Further Work-Up: The chest wall refers to the ribcage and muscles that cover them; the lungs are within the rib cage. A solid nodule in either location, especially if it is new, requires further testing & possible biopsy to determine if it is cancerous or scar tissue; this should begin with a (pet) ct to determine exactly where this nodule is. ...Read more

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

I have a very small nodule on the apex of my lung found on chest X-ray my doctor saidit may be scar tissue or a blocked bone shadow, it is on the apex and I am 70 years old, is it cancer?

I have a very small nodule on the apex of my lung found on chest X-ray my doctor saidit may be scar tissue or a blocked bone shadow, it is on the apex and I am 70 years old, is it cancer?

Hard to say: Although lung cancers can present as lung nodules, most isolated lung nodules are not due to cancer. If you are in doubt, it is better to obtain a second opinion. ...Read more

Possible: Histoplasmosis and granulomas more common in midwest.
Comparison with old x-rays or ct is very helpful.
New multiple lesions, and growth of lesions inclines to cancer. ...Read more

Please tell me what does a lung nodule indicate?

Please tell me what does a lung nodule indicate?

A Lung nodule: Depending on risk factors, a lung nodule may have higher than 50% risk of being malignant. The diagnosis of cancer can only be made by a pathologist upon microscopic examination of a tissue biopsy. ...Read more

Is an 8mm lung nodule followed up by another scan?

Is an 8mm lung nodule followed up by another scan?

Almost always, yes: Depends on your history and the appearance/location/shape of the nodule, but most often a follow up CT scan is the most appropriate test. Occasionally, if your doctor is concerned a PET scan may be useful for 8mm, but if its negative it is less helpful than when you have a larger nodule, for which PET is more reliable at excluding the likelihood of cancer. ...Read more

It is very likely that a 2.6cm lung nodule presents symptoms?

It is very likely that a 2.6cm lung nodule presents symptoms?

Unfortunately, no: Lung cancers are often diagnosed quite late because patients may not have symptoms for a long time. Eventually, people will have a cough, cough up blood, lose weight, have chest pain or shortness of breath. If a nodule is benign, the presence of symptoms probably depends on the exact location (whether it blocks an airway, for example). ...Read more

What should I do for a lung nodule found on right lung?

What should I do for a lung nodule found on right lung?

Get it TNM staged.: If there is a lung nodule, and it appears solitary, it still needs to be evaluated to see if there is no metastasis, etc. Ct scan and an ENT (ears, nose, and throat) exam are done. The ct helps determine if there is lymph node involvement. An aspiration biopsy of the lesion can be taken to determine its histology. Surgical resection in localized cases is done for all types except small cell. ...Read more

What are the symptoms of a lung nodule and are they malignant?

What are the symptoms of a lung nodule and are they malignant?

No symptoms: Lung nodules have no symptoms, unfortunately. Most of the time, they are benign things like scars, but sometimes they can be early cancers. If you have a nodule found on a cat scan, they need to be followed to make sure they don't grow or change over time. This is especially true if you have risk factors for cancer such as smoking or radiation exposure. ...Read more

I have a 4mm lung nodule on my right lung 2 on my left could it be cancer?

Maybe....: ...maybe not. If they are all less than 5-6 mm, there is usually not a whole lot to do other than observation and follow up. PET scans are usually not too sensitive for very tiny nodules. I would defer, however, to the judgement of your physician who knows your situation better and can determine if there is anything else to do now. If you smoke, please stop. Best to you. ...Read more

Can a few lung nodule disappear / cannot see in cxr over a year if you undergo treatment or something?

Can a few lung nodule disappear / cannot see in cxr over a year if you undergo treatment or something?

Yes: "lung nodule/s" is a radiographic finding and not a diagnosis. The presence of nodules does not indicate cancer and the vast majority of nodule are in fact benign (not cancer). They can be inflammation, infection, scar, and numerous other possibilities. As such, yes, many nodules to shrink, "resolve", and/or disappear. ...Read more

What does it mean when a 1cm lung nodule has "small density", does that point toward Cancer? Or Benign?

Small density.: A 1 cm nodule is a small density. Most likely this is benign finding but additional info about appearance and history/ physical exam are important. Are you a smoker? What prompted the X-ray or CT? A 3 month follow-up film is likely needed if this is a new radiological finding. Talk to your doctor. Best wishes. ...Read more

I try to avoid toxic drugs and treatments. What can I try before I go for traditional medical care for lung nodule?

I try to avoid toxic drugs and treatments. What can I try before I go for traditional medical care for lung nodule?

Nothing: 50% of lung nodules may be neoplastic. The only way to establish tissue diagnosis of a non calcified lung nodule is to remove it, and give it to a pathologist to examine under a microscope. The diagnosis of cancer is done under the microscope by a pathologist. Needle biopsy will miss the diagnosis of cancer in a large percent of biopsies. So a negative needle biopsy does not rule out cancer. ...Read more

Found 6mm lung nodule radiologist says no follow up if non smoker I've never smoked but work as plumber don't want to ignore this please advise?

F/up CT 1yr: This is a difficult request to provide an answer in this format. Subcentimeter nodules are rarely malignant. It is suggest that nodules of 4-6mm in size have a 0.8% risk of being malignant in one study to up to a 5% risk in another series.
Risk factors, e.g. smoking, etc may alter the risk. It is generally felt that it would be wise to perform a follow-up CT scan in 1 year with a nodule 4-6mm. ...Read more

Pulmonologist said a lung nodule I have is benign, I still feel uneasy about his answer, should I seek a second opinion? Nodule is 2 CM calcified

Biopsy: A calcified nodule is likley benign. You need to compare thx xray with an old film of your chest if you have. Ct of the chest is helpful. If any doubt tissue biopsy will confirm the nature of this nodule. If you are not comfortable with the response nothing is wrong with getting another opinion. ...Read more

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. ...Read more

Lung nodule found, what is the next step?

Lung nodule found, what is the next step?

Many pathways: Depends on age, size of nodule, history, and smoking history. Options include do nothing (rare), pet scan if there is risk for cancer, follow up cts at intervals determined by experienced md. Biopsies and surgery can come, but generally after above steps. Most nodules (>95%) are not cancer, and therefore invasive procedures should be reserved for when suspicion (guided by above factors) is high. ...Read more

What does a lung nodule indicate? How is it treated?

Usually nothing: Most people, if you go looking, have lung nodules and most are benign scar-like reactions in the lung, and therefore they don't need to be treated any more than a freckle or mole on your skin needs to be treated. Just like moles, some lung nodules (<4% in high risk people) can be cancer and should be followed to see if they change. ...Read more
