What Is A Soft Tissue Pulmonary Nodule In Lung
What is histoplasmosis? Does it affects lungs forming very small nodule, bcz of my lung nodule. Can it be seen in ct, ?
Yes: Yes, it can show as nodules in imagines. Consult your doctor for diagnosis and treatment should it become necessary. ...Read more
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
Fell on my back, had cat scan, revealed (2) 4mm lung nodule pulmonary doctor says I should have nothing to worry about, follow cat scan in 6 mnth?
Probably overkill: For nonsmokers, with nodules in that size range, we recommend no further follow-up. If you are smoker, stop smoking. If any follow-up is necessary, 12 months is probably all you need. ...Read more
Worried about a solid lung nodule 4 mm in 2009 and is now 7 mm, non calcified, smooth borders. Rad said it looks like benign soft tissue, possible granuloma. Do non calcified granulomas grow, and could a cancer grow at that growth rate?
Yes and yes.: Get an opinion from pulmonologist or thoracic surgeon regarding opinion about possible biopsy. It depends whether or not the benefits of biopsy outweigh its risks. ...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
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. ...Read more
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. ...Read more
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 ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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 ...Read more
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. ...Read more
Depends: The pattern of calcification is important. Lamellar, popcorn, central, and diffuse homogenous calcification are usually benign. Anything else that size is very suspicious. ...Read more
Watching for change: The suv is a measure of how metabolically active the nodule is. While there is some overlap between benign/ malignant nodules, a cutoff of suv 2.5 is used for nodules over 1 cm in size. Based on borderline suv and perhaps the ct appearance of the nodule the tests may not reliably tell if benign or not. Short term follow up can show if it grows. If it does grow, that becomes more worrisome. ...Read more
What symptoms can a benign lung nodule cause, and whether it causes blockage and effect on breathing?
Mostly none: In general, lung nodules benign and malignant are asymptomatic (without symptoms). That said, benign is more likely associated with infection. Thus symptoms such as infection and pneumonia may be present; fever, cough, etc.... Other symptomatic nodules may be from sarcoidosis. There is a large list of symptoms with sarcoid. ...Read more
Last xray found 6mm lung nodule but it was not on an xray fromvthe mpnth before. Why so sudden? Ciuld it be a mistake?
See below: Lung nodules are much harder to see on CXR, especially one so small. My guess is it was there, just not visible on CXR. ...Read more
Will a lung nodule have grown since august 7 until today surgeon a said it will have surgeon b said no. It hadn't grown since may?
See below: Blondie, you are going crazy with this! My suggestion, out of my experience, is that you have to find one doctor that you like and trust and go exclusively by what he/she advises you. Seeking multiple opinions is only going to confuse you to no end, and you will not get a medical education out of healthtap. Again, good luck, and get the thing out to achieve some piece of mind! ...Read more
The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
