What Is A Fungal Spore Lung Nodule
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
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
Small, but: Small but big enough to have a work-up or follow-up. See a lung specialist for that. Do you smoke? ...Read more
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
Depends: Depends on what the nodule is? First you need appropriate diagnosis. This is best by a multidiscipline comprehensive thoracic surgical lung nodule program. If the nodule is a tumor, treatment will depend on type and staging if malignant. ...Read more
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
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
The lowest suv (standardized uptake value - a semiquantitative measure of metabolism) is zero.
The maximum suv in a region of interest is called suv max.
Generally, if the lung nodule is less than an suv max of 1, it is likely benign. However, there are plenty of non malignant diseases that can have increased FDG uptake, such as healing fungal lung infections, called granulomas. ...Read more
Why would a t.Surgeon say wait and see, if he thought a lung nodule was a low malignancy in a healthy adult? A
See below: Blondie, I did not realize you are in greece. Medicine in greece is practiced quite differently from the way we do it in the us. They are not that aggressive which may be good or bad in your case. Also unlike here, you won't be able to influence them to do what you want, or seek a second opinion. Is there any way you can come to the us to get treated? ...Read more
A surgeon told me that a lung nodule 2.7 suv is not cancer because cancer shows up at 4.1 and higher, do you agree?
No BronchoalveolarCA: Lower suv values can still be associated with cancer, especially the bronchoalveolar type of cancer. The entire image and clinical status, smoking history and other details need to be considered while evaluating the likelihood of malignancy in a radiologic abnormality. There are risk prediction models available to quantify the risk of a particular nodule being malignant. ...Read more
Doctor said that lung nodule I have is calcified, and due to old glanulomatous disease, how do I know if this is right?
Try 2nd opinion: Calcified nodules are a relatively simple diagnosis either by chest x-ray, or even more reliably, by ct scan. If you have any doubts, get a referral to another radiologist for a second opinion. There will usually be a charge for this, but if it puts your mind at ease it will be worth it. ...Read more
Lung nodule grew from 6mm to 7mm in 5 months. Radiologist said follow Fleschman and GP said rescan in 18 months. Is 1mm growth not a big concern?
6 to 7mm within diagnostic error.
<1 cm overall a much better diagnosis: lots and lots of nodules are seen <1cm.
18 months is too long IF you are a smoker (plus: if you are a smoker---stop now)
At 49 yo, non-smoker: ok to check in 18 months with a benign lesion at 7mm. ...Read more
1 year ago 1 lung nodule 2mm 1year later same nodule 4.5 mm and new one a non calcified punctate at 2.7mm, tiny axillary node should I be worried?
Get it checked,,: At this point, it's hard to say what this is but it must be checked out and followed more closely. It is very important to discuss this with your doctor, run more tests, like a possible biopsy, and initiate the most appropriate treatment because it's clear that it is progressing. Best of luck. ...Read more
Would you operate at once if lung nodule went from 14, 2x10, 9mm-14, 2x 11, 6mm in a 2 month period, round, non smoker 55yo. Thoractomy 2 days later.
Follow for another few month since this may not be a change.
Full history, and review of all xrays and ct scans is appropriate.
If followed for some time already, and no other histoplasmosis or TB history, one might remove it.
The benign ones will stay about the same, and calcify over time.
Fear of delay diagnosing cancer is the issue since early removal has best survival. ...Read more
I have atypical lung nodule dr is attributing to sarcoidosis as have been dx'd by bx of parotid tumor. Pet said suv of 10.9 should this be of concern?
Further w/u.: How big is the lung nodule? Are you a smoker? With suv of 10.9- I think, a biopsy should be done- if possible - (if the size and location allow tissue biopsy to be done).It could be a sarcoidois, but just because you have sarcoidosis-does not mean that this nodule is automatically one. Depending on your risk- other condition including- primary lung malignancy- has to be considered and ruled out. ...Read more
T surgeon said lung nodule has grown 30% since august on 3 d scan its still 1.4 but the inside has grown whatever that means. What should patient do?
Dr found a lung nodule and I cough up little black specks of a tar like substance for the past 6 months. Have a cough but goes away with allergy pill?
Have it worked up: I would imagine that the MD who ordered the CT is going to follow up with you regarding this find and coughing up black is not normal either. Have you been in area that has tuberculosis? Others symptoms. I advise you to make appointment with the doctor to ask some questions and have a follow up. ...Read more
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
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
Nodule: A lung nodule is a round area that is more solid than normal lung tissue. It is a nonspecific finding and can be benign or malignant. ...Read more
Big enough: A 13 mm lung nodule warrants a pet/ct scan. This will identify things like calcifications seen in benign nodules and will determine if sugar uptake is high as seen in infection or tumor or low indicating scar. Depending on the likelihood of cancer, a ct guided biopsy is possible in most peripheral nodules greater than 9mm. Lung cancer is increasing in nonsmokers, women and the young in u. S. ...Read more
Relax: Sometimes, we as physicians use that word loosely. I did not mean to be lackadaisical. I am sure you are concerned and I am only trying to calm you down. I see you have other conditions being followed by your doctor. Have a good talk with your doctor as to the best way of finding out and options of treatment. Lung cancer is very rare at your age anyhow. ...Read more
