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

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

Chest CT scan subsegmental atelectasis versus fibrosis in medial margins of r \l upper lobes abutting mediastinum was f/u for 6mm ground glass nodule

Chest CT scan subsegmental atelectasis versus fibrosis in medial margins of r \l upper lobes abutting mediastinum was f/u for 6mm ground glass nodule

The fibrosis and : Atelectasis isnt anything to worry about, just some lung tissue collapsed on itself and scarring. The ground glass nodule is something that may need longer term follow up to make sure it doesnt grow. These can be due to something called atypical adenomatous hyperplasia (aah). ...Read more

Three lung nodules found on CT in dec, each 5mm. Stable on repeat CT in may but one is a ground glass nodule. Should I have a bronchoscope?

Three lung nodules found on CT in dec, each 5mm. Stable on repeat CT in may but one is a ground glass nodule. Should I have a bronchoscope?

More details: Why did you have the ct scan in the first place? Where, fever, cough, weight loss, shortness of breath, infection, exposure to fungus, smoker? Family hs, other disease? Stable for 6 month without change in size is not assuring enough. 3 nodules in the lung in 35 yo female can be due to many reasons..Skin testing, blood counts, liver enzymes. Ask your doctor why? You and i need to know more. ...Read more

Should i worry about my chest CT scan showing multiple patches of ground glass infiltrates on my lungs?

No not usually: Usually these are findings due to prior swelling or infection in lungs; even based on where you grew up. We use stability on cts to confirm benign nature. Sometimes treatment w/ antibiotics considered. Biopsy considered with hi risk though age & smoking history important. ...Read more

Lung lesion: At your age and with this description i would think there is an overwhelming chance that this lesion is benign. I agree with a repeat scan in a couple months. If it grows a ct guided needle biopsy could be performed by an interventional radiologist. ...Read more

CT had 1.6cm & two 7mm ground glass nodules in lungs after 6 mo of cough & chest pain. Had blood clots in lungs 2x. Ex smoker. Could it be cancer?

Absolutely possible: The only way to get a definitive diagnosis is to get a biopsy and look at the tissue under the microscope. If it is in a single lobe it may be best to remove the whole lobe. Speak to iour local pulmonologist and your thoracic surgeon ASAP. ...Read more

1cm ground glass nodule RLL. Pneumonia in October 2014. 42 yo male with no hx of CA. 1PPD smoker x 20 years. Should I be concerned for cancer?

Possibly: ground glass nodules, particularly in current or former smokers need to be evaluated. Depending on its density, a PET scan may be helpful but at a minimum the nodule needs to be proven stable in size for a period of two years to assure its benign. You need to see a pulmonary MD to have it evaluated as some require resection to know the diagnosis. ...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

Can radiologist tell by looking at ct scan if a lung nodule is cancerous my is 6mm he does not think no follow up needed should I get a follow up scan?

Can radiologist tell by looking at ct scan if a lung nodule is cancerous my is 6mm he does not think no follow up needed should I get a follow up scan?

Incidentaloma: There is a low likelihood of malignancy in subcentimeter nodules. To some extent there are important distinguishing factors - the benign appearance of calcification appearance, whether it is smooth, lobulated or spiculated and your personal smoking history. It is possible that the radiologist was able to make that call on features that made it likely benign, such that there was no decision needed ...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?

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

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

Saw a 3 mm nodule during a CT scan at the base of my left lung. What could it be?

From nothing: To an early something. The anxiety you are experiencing is given as a main reason to not do screening ct's in smokers. 3 mm is too small to worry about. If it were me, i'd re-ct in 6 months to a year to check change in size. You can google the nlst - national lung screening trial. Do you smoke? Time to stop if yes. Good luck. ...Read more

See a lung doctor: any lump or mass need to be checked regardless of the size 9 mm is not a large mass but it still need to be checked and biopsy if possible if you are a smoker i will take it more seriously you still have a lot of reason for the lump to be benign but still need to be checked good luck ...Read more

If I've had a CT scan of mu lungs and there was a subpleural nodule found 6mm should I get a pet scan? And could this be cancerous?

No: The chances of you having cancer at your young age (25) are rare. The odds of a solitary 6mm lung nodule being cancer in your age are even rarer. A biopsy would be more appropriate if your physicians thought this was cancer. ...Read more

Radiation from CT: This issue should be discussed with your pulmonary doctor and radiologist. There is some risk associated with the radiation from multiple ct scans. However, that risk is likely small compared to the risk of a nodule identified in the lung, and may not outway the risks of ct, in the long run. There should be a plan with a reasoned approach that minimizes the risk of ct that you can agree with. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
