Had ct scan was told have very small nodule on lung not to worry have primary dr. X-ray yearly should I be concerned?

Lung nodule: Depending on the size of the nodule as well as your risk factors, follow up is usually with a repeat CT scan in 6-12 months.

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

Dr found a very small lesion on my lung, I worry about it but he said its so small we don't need a CT scan. How do I ease my mind?

Dr found a very small lesion on my lung, I worry about it but he said its so small we don't need a CT scan. How do I ease my mind?

Small lung lesion: Most very small lesions/spots/nodules seen on chest x-ray are benign temporary findings or calcifications. The usual recommendation is for repeat x-ray in 1 year, or perhaps 6 months if you have risk factors (smoking, risk of TB or other lung infection). if there is change, such as increased size then a CT scan may be appropriate. Again most of the small findings on CXR are benign.

I was recently told that I have a small 5 mm lung nodule. Discovered by CT scan. I am not a smoker. Never have been. Should I be worried?

Fleischner criteria: Nodules are common, and tend to scare people. The following link has criteria often followed by radiology groups regarding your findings. Be cautious, but not worried. Best wishes. Http://www. Snm. Org/docs/pet_coe/off_the_wall/fleis. Pdf.

Ct scan shows small pluralparenchymal opacity in left lung base anterior to cysts what does it mean?

See your doctor: Your question could mean a lot depending on your history, you are quite young why did you have a CT? Do you already have any kind of cancer, what Cyst are you talking about>? basically in this situation you should talk to the doctor who ordered your Ct scan as the history matters a lot

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.

Lung CT scan impression: multiple small nodules largest 6mm ill-defined semisolid noncalcified medial left upper lobe?

Lung CT scan impression: multiple small nodules largest 6mm ill-defined semisolid noncalcified medial left upper lobe?

Lung Nodules:: It is fairly common for people to have benign lung nodules that are incidentally found on ct scans. Would recommend a follow-up scan in a few months just to make sure they are not growing. If you smoke, please stop! But, I wouldn't be too worried about these small lung nodules. Check back with your physician for a follow-up plan.

Is it feasible to have had small cell lung cancer causing malabsorption for 1 year but not show on CT scan.

Is it feasible to have had small cell lung cancer causing malabsorption for 1 year but not show on CT scan.

No: Although a negative CT does not guarantee that you are totally free of cancer cells, your malabsorption has nothing to do with the cancer. If you have received radiation for the condition, then that Rx might potentially though unlikely lead to GI changes.

Had lower left pneumonia March 4. Right lung had some fluid. Ct scan yesterday showed left lung clear. Right small fluid and atelectasis. What now??

Resolving pneumonia: Do you have an incentive spirometer to encourage deep breathing and expansion of the lung? You can buy them online, even from Amazon or a health supplies store/site. Blowing an instrument, singing, blowing up a balloon, and simple deep breathing exercises as well as being more active out of bed will help resolve it.

Is it true that the primary tumor in small cell lung cancer is often occult? Does this mean even a CT scan can't see it? Do we only detect on spread

At some point: In its development, every cancer is "occult" because it originates on a microscopic level. CT has a high sensitivity for detecting lung cancer, approximately 95%, so CT will detect the vast majority of lung cancers.

March 4 lower left pneumonia. X-ray yesterday white lower left lung still. Ct scan today showed small atelectasis or small fluid lower left. Resolve?

March 4 lower left pneumonia. X-ray yesterday white lower left lung still. Ct scan today showed small atelectasis or small fluid lower left. Resolve?

Likely ok: Radiographic resolution of pneumonia is typically slower than (lags behind) clinical resolution. What does the report impression say?

Are small nodes seen on lungs thru chest CT scan suggesting lung cancer or something else?

Are small nodes seen on lungs thru chest CT scan suggesting lung cancer or something else?

Not necessary: Are you referring as small lymph nodes or small nodules on the lung? There are other conditions beside cancer that can be presented with small nodes - including infections, inflammation, autoimmune process, etc. So, a good history, examination, blood work and serial imaging would be necessary to be done. Discuss with your md in detail.

Is it feasible to have had an occult small cell lung cancer causing malabsorption for 1 year but not showing on CT scan?

Is it feasible to have had an occult small cell lung cancer causing malabsorption for 1 year but not showing on CT scan?

Very unlikely: First lung cancer causing malabsorption is very unlikely Second for this to last one year without progression is very unlikely in SMCLC. I think you need to have the dx reevaluated. Best wishes

30 yo female, former light smoker 4-5 yrs. CT scan in 2013 with small lung nodule, but no follow up. Should I be worried? The doctor was unconcerned.

30 yo female, former light smoker 4-5 yrs. CT scan in 2013 with small lung nodule, but no follow up. Should I be worried? The doctor was unconcerned.

Lung Nodules: Depending on the size, there are specific criteria that have been developed called the "Fleicshner criteria" that will determine if any further testing or repeat CT scans need to be done. Discuss in further detail with your Doc to be safe, Best wishes.

Can small cell lung cancer cause malabsorption through zolinger Ellison syndrome. Would this be a presenting sign of sclc before it shows on ct scan?

Can small cell lung cancer cause malabsorption through zolinger Ellison syndrome. Would this be a presenting sign of sclc before it shows on ct scan?

Uncommon: Most Zollinger-Ellison / gastrinoma are from islet cell tumors of the foregut. Oat cell carcinoma can produce other paraneoplastic syndromes, famously the anti-nerve cell ones, before being visible on chest ray, but it announces itself fast enough. And what are you going to without a localized tumor? Take out both lungs? Look for some other cause for any suggestive symptoms. Good question Gill.

Hi docs, can you tell me if small nodes seen on lungs thru chest CT scan are suggesting lung cancer?

Hi docs, can you tell me if small nodes seen on lungs thru chest CT scan are suggesting lung cancer?

Multiple causes/risk: This is one possibility, and the assessment of that diagnosis involves a visit with to a pulmonary specialist. They will recommend further evaluation. If there are multiple nodules, this actually may be related to infection. One example of such an infection is TB. If you have smoked in the past, swollen lymph nodes on the chest CT, or signs of illness, this raises the risk for a malignancy.

Ct scan showed very small lung nodule. I've had 3 chest x-rays prior and nothing showed on them. What happens now? How to determine if it's cancer?

Ct scan showed very small lung nodule. I've had 3 chest x-rays prior and nothing showed on them. What happens now? How to determine if it's cancer?

Depends: If the nodule is very small, it would not be seen in a plain x-ray so the fact you had 3 prior negative ones does not mean much. You may have had it undetected for years. Depending on how big it is and your clinical situation, your doc may opt to follow up with another ct scan in 6-12 months, do a pet scan, or proceed with a biopsy. Good luck and if you are a smoker, quit today.

Lung CT scan showed small areas of ground glass opacity on upper rt. Lobe consistent with mild pneumonitis. Is this cancer? When should I repeat scan

Lung CT scan showed small areas of ground glass opacity on upper rt. Lobe consistent with mild pneumonitis. Is this cancer? When should I repeat scan

Depends: On size of lesions and risk factors such as smoking. However, first follow up scan is typically in 3 months. More scans will follow, usually every 12 months, to make sure no cancer present.

Might it be lung cancer if I had a CT scan done of the chest and it showed 4 small nodules and now I have pain under rib cage?

Might it be lung cancer if I had a CT scan done of the chest and it showed 4 small nodules and now I have pain under rib cage?

Unlikely: Though it is possible for lung cancer to cause pain in the wall of the chest, this usually happens when tumors are larger. The nodules you have will need followed with additional ct scans or biopsied/removed depending on size and your risk for lung cancer. However, it's unlikely for small nodules to be the cause of your pain. Check with your pcp or see a lung doc about the nodules.

Would you expect a small cell lung cancer that was causing fatigue and muscle loss to be picked up on a low dose CT scan.

Yes, probably.: If you are symptomatic, I would think the tumor would be large enough to see on CT, even if only a few mm in size

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
