Increase Size Lung Nodule
If a size of lung nodule increases from 8mm to 20 mm, is it always cancer, or could it stil be an infection causing increase in size, thanks?
No: A lung "nodule" is a term for small abnormalities seen on xray and ct scans. Most are found to be non-cancer. If larger, 2.5 - 3cm or bigger, call it a "mass". All lung nodules and masses should be evaluated and followed by referral to a comprehensive thoracic surgical cancer program. Integration into a comprehensive program saves lives and decreases unnecessary morbidity. ...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
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?
Is a lung nodule which is 7cm in size not very big though described as benign by 1st CT scan with a 2nd CT in 6 mnths should I be concerned about 7cm?
Need to check: The report again. 7 cm or 7mm or 0.7 cm? If lesion really 7 cm, it needs work up now. If 7mm (same as 0.7cm) then 6 month follow up scan ok. ...Read more
What's a difference between lung nodule and intrapulmonary nodule? What's smallest size in mm that can be detected on CT scan?
No difference: They are two terms for the same thing. The smallest size detectable depends on the type of CT scanner and the technical parameters of the scan. A high resolution, thin section scan could potentially detect lesions 1mm or so in size. ...Read more
Had 6 negative CT scans for a benign lung nodule in my early 40s. Is my risk of cancer increased, by how much and how many years down the road?
Cannot predicy: If after all those CT scans there has benn no change in the finding, then the likelihood it is nothing to worry about. Your risk of cancer is not increased by this nodule or the CT. There are never any guarantees that you won't get cancer. A healthy life style without smoking and the like will certainly be in your favor. Good luck ...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
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
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
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
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
X-ray spot: It can be anything from an old inactive walled-off TB of fungus infection to a benign tumor to cancer to something as exotic as a dog heartworm that went far astray. Here in kansas, most are old histoplasmosis. But a spot is lung cancer until you & your physician have a reason to think otherwise. Good luck, and be brave. ...Read more
Solid mass in lung: A lung nodule is a soft tissue mass that is located somewhere within the lung itself. It can be a benign or malignant nodule. Following it with ct scans to see if it changes in size is one way to manage them or going directly to biopsy. ...Read more
Many options: 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

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
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
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
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
