My chest X-ray showed something wrong but the CT Scan was clear. What could it be? They thought it might be a collapsed lung or cancer. I have to wait a week to see the doctor. I am scared.

May be nothing. If the ct was done after the xray, then there is a good chance that there was nothing there. Chest xrays occasionally suggest abnormalities that are not found on ct scans; however, the ct scan is much better at demonstrating pathology. If the ct was normal, i wouldn't worry very much. But, make sure you follow up with your doctor. Read more...
CT scans. Are much more sensitive than plain chest x rays. If it was clear, the chest x ray abnormality was probably nothing. It is unlikely that this is cancer. Read more...
Shadow, overlap. A chest xray is really a shadow of a patient's lungs and chest, taking 3 dimensions and "squashing" it down into 2. Sometimes, those overlapping structures form a "summation shadow" which can look like a nodule. Since the radiologist wants to be sensitive and not miss a possible problem, they comment about it in the report and perhaps recommend a chest ct. Read more...
Relax. Plain chest xray shows sometimes a lot of things but if ct is negative you can relax. I would still quit smoking especially if you are short of breath and apparently you have asthma not quite well controlled on current meds, it will help. Read more...

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. Read more...

CT scan "Tiny nodule in subpleural right lung base" 34f smoked 13 yrs quit 2 wks doc says rescan in few mths. I can't stop worrying it's lung cancer?

Follow up scan. what are the size of the tiny nodules to be precise here? if they are so small like a few mm only, there is nothing much you can do at this time anyway as biopsy would likely not be able to be done due to the limited size. No need to worry at this time. people can have scarring or granuloma which can be presented as small lung nodules. You definitely need to get a follow up CT scan to compare them. Read more...

Would my doctor be able to see whether my lung cancer has spread to my lymph nodes on a CT scan?

Not definitely. Clinical stage refers to our best guess based on imaging studies, such as chest ct, pet/ct and brain mri, and minor procedures, such as mediastinoscopy, lung biopsy and something called endobronchial ultrasound needle biopsy, or ebus. Ct scan alone is not very sensitive for detecting cancer in lymph nodes. Read more...
Yes, but with just a. Little more accuracy than a coin-flip based on size. Ct's miss small things, and falsely label benign things cancer. Proving nodal positivity is helped with pet scans, endoscopic ultrasonography with esophagoscopy or bronchoscopy, and sometimes surgery. Why the fuss? If nodes are +, the role of surgery is limited, and surgery is no picnic, and despite trying to prove its benefit, we're not sure. Read more...
Not really. Agree with dr cooke and others. A ct scan can tell you if the nodes appear to be abnormal. Ct scan does not diagnose cancer and can not tell you if there is cancer in the lymph nodes. If you have cancer, abnormal nodes may or may not be because of the cancer. You would need tissue/node biopsies to determine if there is cancer in the nodes. Read more...
Not with certainty. If there were enlarged lymph nodes on ct, that would be very suspicious for lymph node metastasis. Unfortunately, a normal sized lymph node can still have cancer cells in it, so ct is not specific. Pet/ct is somewhat better, since it looks for increased metabolism as well, but it also can miss tumors that are very small (<5 mm if very hyper metabolic, <1 cm if less hyper metabolic). Read more...
