Cancer (Definition)

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 more

What is CT scan usual result for lung cancer?

"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 more

What is the definition or description of: pet-ct lung cancer diagnosis?

What is the definition or description of: pet-ct lung cancer diagnosis?

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 more

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

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

Is it possible to get lung cancer from a spiral CT scan?

Is it possible to get lung cancer from a spiral CT scan?

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 more

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. ...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
