Do Benign Lung Nodules Grow
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
Do benign lung nodules grow, and is it possible for a carcinoid not to have any growth in 8 months?
Yes: But there are very few truly benign solid tumors that occur in the lung. The only type seen with any frequency are hamartomas. Lung nodules that are made of scar do not generally grow except when they form, granulomas are burnt out infections that also don't grow. Any solid lung nodule that is increasing in size needs to be proven not to be cancer with biopsy ...Read moreSee 2 more doctor answers
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?
Lung nodule didn't grow for 6 months and now 15% first 2months 10 the next and now 5%.Should it be operated on now or is it safe to wait 3months?
I wouldn't wait: A lung mass which is increasing in size is very concerning for cancer. Waiting a week or so probably doesn't make a difference but waiting 3 months would make me uncomfortable. You have already watched it for 9 months. Another 3 months means you have observed this lesion for a year! ...Read moreSee 2 more doctor answers
I ve multiple lung nodules, expecting key hole surgery to test it, if it comes out benign, later will dr be able to remove them or better to leave them?
Lung nodules: Can't be ignored. Some are more suspicious than others. Age, smoking ; other factors are key. Characteristics of nodule, like calcification, may suggest a benign cause. Surgical or needle biopsy can help define some nodules, but sampling error (missing what you aim for or biopsing a benign nodule when a malignant one may be lurking elsewhere) can occur. True benign nodules don't need to be removed. ...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 moreSee 1 more doctor answer
Are subcentimeter lung nodules that have not changed in size since january assumed to be benign if they do not light up on a pet scan. All are 6 mm?
Not necessarily : Six millimeter nodules are small and may not light up in a pet scan even if malignant. However, the fact they are stable is encouraging. I would guess your doc will keep an eye on them unless there's something else that is suspicious for cancer. Good luck. ...Read moreSee 1 more doctor answer
How often do benign lung nodules change to cancerous, or do they all turn over a period of time?D
Generally don't turn: Key factor is change in size; benign nodules tend to stay roughly the same size over time, malignant nodules don't-they get bigger more rapidly. Benign nodules are common-aftermath of prior infection, inflammation, etc. Smoker? Ex- smoker? Lived/worked with a smoker? Occupational exposures? Family history? All are factors to be considered. Get follow up with your md, and/or pulmonary specialist. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
I have multiple lung nodules with a history of oral cancer. Bronchoscopy was benign, but nodules could not be reached.. Chances this metastatic?
Could be metastatic: Lesions of lung associated with oral cancer is not that uncommon. Higher possibility of such disease in lung would correlate better if cervical nodes had been present initially. Bx is essential to initiate therapy if needed. A PET/CAT could indicate possibility of lung mets. Thorascopic bx would be helpful for deciding on definitive management. ...Read moreSee 1 more doctor answer
