What Does Lung Cancer Look Like On A Catscan
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
See answer: Pulmonary ct is extremely sensitive in identifying lung nodules. When found, these nodules then need to be appropriately evaluated either with followup lung ct, pet-ct, or direct tissue sampling. Your clinical dr. Can best advise you – or you can be seen at a dedicated lung nodule center. ...Read moreSee 1 more doctor answer
"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
No such thing: Pet scan identifies increased cellular metabolism. The suv is a measure of how metabolically active a "spot" or "nodule" is. It does not diagnose. Lung cancer (all cancers) is diagnosed by obtaining tissue and examining by pathologist. Any lung nodule must be thoroughly investigated and closely followed by a comprehensive thoracic team. ...Read moreSee 2 more doctor answers
Had multiple chest xrays and CT of chest with contrast. Still having difficulty breathing and feel like thick phlegm stuck in throat that I can't get rid of. Saw ENT as well. Could it still be lung cancer?
I took the eatly cdt lung cancer test. They were all negative except the mage4. Ct was clear. Does this mean I have cancer elsewhere? Or it is to come
Unclear: Not sure why test was performed. The data of this test/technology is still preliminary. Antibody biochemical assays may identify the presence of tumor/cancer years before they are large enough to find by radiology; therefore before we can actually treat. If used, results should be integrated into overall risk assessment, screening, surveillance. Test should not be routinely employed without a plan. ...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.
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
