6mm nodule left lung base pleural surface and faint 6mm nodule on left lower sub pleural lobe found from CT. Enlarged heart found on right side. Also very slight alveolitis found in right upper lobe. ?

Nodule: A 6mm nodule is a relatively common finding. Many times these are benign resulting from old infections or exposures. It becomes more worrisome in a smoker, and regardless should have a follow up cat scan in 3-6 months. ...Read more

Lung (Definition)

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

Ct scan found a lesion on my liver, a 6mm nodule on my lung, 2 tracheal lymph nodes 1cm each?

Ct scan found a lesion on my liver, a 6mm nodule on my lung, 2 tracheal lymph nodes 1cm each?

Follow up CT: The importance of the findings may depend on why your ct scan was done. Current guidelines suggest Incidental single lung nodules between 4-6 mm in patients over 35 need follow ct scan, the interval between scans is dependent on the risk of cancer (smokers, exposure to asbestos, etc). 10mm(1cm) lymph note near trachea is upper limits of normal size. ...Read more

Had a ct scan and have a 6mm nodule on the lung radiologist said no follow up if not a smoker should I be worried about cancer I'm not a smoker?

Had a ct scan and have a 6mm nodule on the lung radiologist said no follow up if not a smoker should I be worried about cancer I'm not a smoker?

See below: Worrying is not a useful option. About 10% of the lung cancers in occur in non-smokers. It would be prudent to consult your primary care provider, who would know more about your health, for the advisability of a PET scan, MRI, other action or watchful waiting. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more

Will a 6mm lung nodule show up on a pet scan?

Will a 6mm lung nodule show up on a pet scan?

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

Recently discovered a 6mm lung nodule during ctshort history of smoking around 18-20 sociallyshould i be concerned as a high or low risk patient?

Low risk: Your smoking history is relatively short. A 6mm nodule would be observed for 3-6 months before repeating the scan. The overwhelming majority (>95%) of nodules seen on ct are benign. If you stopped smoking, congratulations. If not, strongly consider it. ...Read more

Noncalcified 6mm upper lung nodule. Stayed that way for 3 years. 4th year it grew to 8.4mm. 5th year is 1.2cm. Could this be slow growing cancer?

Noncalcified 6mm upper lung nodule. Stayed that way for 3 years. 4th year it grew to 8.4mm.  5th year is 1.2cm. Could this be slow growing cancer?

Yes!!! : Lung nodules are checked every 6 months for 2 years. If they dont change in size, they are considered stable, and annual cxr is in order. If it grows, it could be malignant. 6 mm to 1.2 cm is a lot of change, so see your primary care doctor for a pulmonary consultation. ...Read more

Found 6mm lung nodule radiologist says no follow up if non smoker I've never smoked but work as plumber don't want to ignore this please advise?

Found 6mm lung nodule radiologist says no follow up if non smoker I've never smoked but work as plumber don't want to ignore this please advise?

F/up CT 1yr: This is a difficult request to provide an answer in this format. Subcentimeter nodules are rarely malignant. It is suggest that nodules of 4-6mm in size have a 0.8% risk of being malignant in one study to up to a 5% risk in another series. Risk factors,e.g. smoking,etc may alter the risk. It is generally felt that it would be wise to perform a follow-up CT scan in 1 year with a nodule 4-6mm. ...Read more

When my 6mm lung nodule was found on CT, slight "alvelitis" was found on the right upper lobe. What is alvelitis?

When my 6mm lung nodule was found on CT, slight "alvelitis" was found on the right upper lobe. What is alvelitis?

Alveolitis: This is inflammation of the Alveoli,...the pulmonary (lung) alveoli are the terminal ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, and which are both sites of gas exchange with the blood as well. ...Read more

CT for K-stone in July found 6mm nonclassified lung nodule. 2nd K-Stone in Sept and 2nd CT. No mention of nodule. Can they disappear? Do I need 3rd CT

Yes, no: Yes nodules can disappear, butr make sure the radiologist was also reviewing CT for it, he may have been focusing on just the kidneys. With more kidney stones, you may want to check calcium levels and/or parathyroid hormone levels ...Read more

Had ct scan found 6mm lung nodule radiologist says if non smoker no further follow up should I be concerned I'm a no smoker what is my best option?

Lung nodule: Lots of people have nodules, oftentimes called an "incidentaloma" found on imaging studies. Speak with your primary care doctor to determine if a follow up image is necessary. If you are concerned, a repeat image in 6-12 months can be done to evaluate for changes in the nodule. ...Read more

Just had ct scan found 6mm lung nodule doctor and radiologist not concerned about follow up scan what should I do? Just looking for second opinion

Just had ct scan found 6mm lung nodule doctor and radiologist not concerned about follow up scan what should I do? Just looking for second opinion

You have a choice: Lung nodules are considered benign if they contain calcium. So check if yours are calcified or not? If they are not calcified then a follow up CT scan may be justified provided you are a smoker. A second opinion may be useful if you are anxious about your present situation. Otherwise go see your doctor in 6 months. A chest X-ray may be another alternative to check the lung nodule for any fur growt ...Read more

After pneumonia, 6mm ground glass nodule found in lung 7 years ago. Recent CT scan showed 11mm non-calcified nodule in very same area. Did it grow?

After pneumonia, 6mm ground glass nodule found in lung 7 years ago.  Recent CT scan showed 11mm non-calcified nodule in very same area. Did it grow?

Possible granuloma: This may be a post-inflammatory granuloma, but that is hard to tell without multiple serial exams. If you have risk factors for lung cancer, such as a history of tobacco use, a pet/ct could be obtained to evaluate for abnormal increased metabolic activity in this nodule. Discuss with your md. ...Read more

Should 5mm nodule on lung be removed?

Should 5mm nodule on lung be removed?

No, almost NEVER: A 5 mm lung nodule, even in a high risk person (heavy long time smoker) has a (much) less than 1% chance of being cancer as opposed to a benign scar or 'granuloma'. Nobody should be doing surgery to remove a 5 mm nodule except in the rarest of circumstances, too complicated to discuss in 400 characters. ...Read more

If you have a single nodule in each lung are they considered separated solitary nodules or multiple nodules?

If you have a single nodule in each lung are they considered separated solitary nodules or multiple nodules?

Multiple nodules: Solitary nodules appear only in 1 lung. A single nodule could have multiple causes (infection, lymph node, cancer, others). However, 1 nodule in each lung would constitute an unusual finding. It deserves investigation, as both have a greater chance of being malignant (cancer). The only way to know for sure is by biopsy - "if tumor is the rumor, tissue is the issue". Talk to ur doctor soon. Good lu ...Read more
