If your suv number is 2 and CEA a 5.6 does that mean lung nodules are cancerous?

If your suv number  is 2 and CEA a 5.6 does that mean lung nodules are cancerous?

Maybe: A standard uptake value of more than 2.5 would be more worrisome, and a blood cea of 5.6 can simply mean that you smoke. Regardless of these results, you are going to get the nodule(s) biopsied; especially if they are multiple, the result may be something treatable that is low on the list of entities that you may already have considered. Good luck & stay proactive; there are lots of new rx's here. ...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

X-ray said lung nodule about 1.2 in feb, aug 1.4 2.7 suv, pet, oct 1.5ct .Has it grown or not? Could it be cancerous after 8 months?

Yes and no: 1.2 to 1.5 cm is not a lot of change and it may be positional, but if real bear in mind that cxr and ct are 2-dimensional and the lung nodule is 3-dimensional so it may account to doubling in growth. Also see all my previous answers, blondie:). ...Read more

Can you tell me if a person has a history of cancer and has lung nodules, could these nodules be cancerous?

Can you tell me if a person has a history of cancer and has lung nodules, could these nodules be cancerous?

Yes: If you have a history of cancer, and there are lung nodules found, they must - at the very least - be followed very closely with multiple ct scans. They can definitely be cancerous. Now, having said that, they may just be scars or temporary infections, etc. But, you have to follow them closely. Good luck! ...Read more

How often do benign lung nodules change to cancerous, or do they all turn over a period of time?D

How often do benign lung nodules change to cancerous, or do they all turn over a period of time?D

Generally don't turn: Key factor is change in size; benign nodules tend to stay roughly the same size over time, malignant nodules don't-they get bigger more rapidly. Benign nodules are common-aftermath of prior infection, inflammation, etc. Smoker? Ex- smoker? Lived/worked with a smoker? Occupational exposures? Family history? All are factors to be considered. Get follow up with your md, and/or pulmonary specialist. ...Read more

9 mm uncalcified lung nodule followed for years said to be hematoma now how would they know unless they biopsies despite ct/pt scans could it still be cancerous regardless of no growth?

9 mm uncalcified lung nodule followed for years said to be hematoma now how would they know unless they biopsies despite ct/pt scans could it still be cancerous regardless of no growth?

Very unlikely: Lung cancer grows, doesn't stay stable for years. Ctand pet scans are excellent (not perfect) at picking up worrisome nodules, especially of significant size (say 9mm). Biopsies carry some risk-collapse lung, bleeding, infection, so they are done if needed in questionable cases, or to confirm diagnosis of cancer fto plan and gauge treatment. ...Read more
