Lung Nodule Caused Sinusitis
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. ...Read more
Yes: Is the short answer. Asbestos can cause several different changes to the chest and lung fields. Pulmonary nodules are just one example. Pleural disease including plaques and calcification as well as mesothelioma are side affects of asbestos. Lung cancer is also a problem. Don't ignore this nodule. Talk to your doctor. ...Read more
Benign or malignant: Multiple possibilities. It's critical to obtain a thorough evaluation. All patients found to have a lung nodule should be referred to a comprehensive multidisciplinary thoracic surgical oncology program. After review of characteristics of nodule, patient history, risk factors, and examination; an individualized plan can be devised to facilitate diagnosis and/or treatment. ...Read more
Is it better to be safe than sorry, when one has a lung nodule 1.4 2.7 suv and get it removed or wait and perhaps cause more problems. Surgery seems so?
It depends: It depends on the patients medical history, smoking history, whether or not the nodule has grown over time, and what exactly it looks like. The patient's peace of mind is a factor as well. If a patient feels strongly that he would like a lung nodule removed that should factor into the equation also. ...Read more
Back in 1972-74, I was on a U.S Navy shift aircraft carrier, which was full of asbestos. In 2005, I was diagnosed with that left lung nodule, which was removed in 2008. In your personal opinion, do you think that may have caused my lung nodule? If so, ple
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
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
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
Can asthma cause lung nodule in non smoker 52 yr/F had chest xray april - negative, now chest xray july nodule showing?
Lung tumor: Chest or mediastinal lymph nodes associated with a lesion in the lung most often represent metastasis from a lung primary. This can further be defined by mediastinoscopy and lymph node biopsy or if in the proper position, thoracoscopy removing the lung nodule. A PET/CAT before any procedure will tell whether the nodes are malignant as whether the lung lesion is malignant. ...Read more
Pls advice me what symptoms a lung nodule would normally cause? Mine is 8mm, unrelated to dilated bronchi, would it increase in size if its not cancer?
Could 4mm lung nodule cause fatigue&muscle loss for 1year? Tested positive on early cdtlung blood test. Sodium slight low cortisol slight high. Advice?
See an oncologist: Now is the time to find out if that nodule is, indeed, cancer, and a specialist's recommendations are the way to go. If so, that could be causing your fatigue. The muscle loss may be due to de-conditioning (not using the muscles enough), due to your fatigue. If it IS cancer, you are catching it at a very small size and there is a much better chance for a cure! ...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
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
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
