What Does Lung Cancer Look Like On Ct Scan
"Nodule": A solid mass or nodule however it is difficult to define benign vs malignant. Pet/ct may more helpful where there is suspicion. However, this may also limited in differentiating infection/ inflammation from cancer. That being said, imaging does not arrive at a pathological diagnosis. When possible, any suspicion of lung cancer requires pathological confirmation through a biopsy. ...Read moreSee 2 more doctor answers
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Possible Not Likely: Medical radiation is estimated to cause about 1% of cancers. Patients trested with radiation therapy have about a 0.5% chance of having a radiation related 2nd cancer. The risk from a single spiral ct is considerably less and would likely occur 10-20 years after the exposure. Bottom line is that tests like ct scans should only be ordered for good reasons. ...Read moreSee 1 more doctor answer
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 an occult small cell lung cancer causing malabsorption for 1 year but not showing 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. ...Read more
Does early stage smalcell lung cancer cause malabsorption? I have had malabsorption for over a year, but a CT scan was clear in Feb, but still worried
See below: Small cell cancer of the lung does not cause malabsorption. Had you had untreated small cell lung cancer for a year, you would likely have the tumor all over in your body. 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. 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. ...Read more
Not likely: The natural exposure one might get just from where you live may exceed 3msv per year. Living in denver, you might be exposed to 6msv per year. Risk of developing cancer from a properly conducted ct scan is low. I believe the estimated average radiation exposure for a single chest ct is about 5-7msv. A low dose chest ct is about 2msv. ...Read more
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 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
