Detecting Lung Cancer Fainting
Sometimes: Sometimes 8-10 mm lung lesions can be detected. Detection depends on location of lesion whether it is central or peripheral. Central lesions near mediastinum are many times difficult to recognize on plain radiograph. Cross sectional imaging such as CT is much more sensitive for small hidden lesions than radiograph. ...Read moreSee 1 more doctor answer
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
It is: possible, but a cardiac MR is not optimized for breast evaluation, so breast cancer detection on cardiac MR is likely to be accidental and imprecise. It cannot substitute for the standard breast imaging techniques such as mammography, sonography, and breast MR. ...Read moreSee 2 more doctor answers
No: A CAT scan is used to visually define the extent of metastatic colon cancer in the liver should metastasis be present. Liver failure is a condition measured by functional abnormalities that occur within the liver usually due to parenchymal damage such as inflammation from hepatitis . Here one measures serum enzymes and the presence of elevated alkaline phosphatase and bilirubin in serum. ...Read moreSee 1 more doctor answer
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
Depends on stage: The long term prognosis of lung cancer depends on the stage of the cancer. The stage (1-4) depends on the size of the tumor and whether it has spread outside of the lung to lymph nodes, the lining of the chest wall (pleura) or other organs (liver, brain, etc). Some of this information may be determined by x ray test (ct scan, pet scan) and some may require biopsies to determine. ...Read moreSee 3 more doctor answers
Often: Ct scan is a very good way to detect pancreatic cancer, but there are a few caveats. One, no test is 100% accurate. Two, some cancers may not be detected on ct scan because of the way the study was performed. Three, some may not be detectable due to small size or location. There may need to be other tests such as ERCP or endoscopic ultrasound. ...Read moreSee 2 more doctor answers
Depends: Staging, location, degree of emphysema, co morbidities will determine symptoms on a particular individual. In general, most patients have no symptoms until late. Bloody sputum sometimes occurs. Some tumors may produce hormones. Weight loss may occur with advanced stage. Pneumonia, stridor, bloody pleural effusions, horner's syndrome, chest wall arm pains. Shortness of breath, recurrent pneumonias. ...Read moreSee 1 more doctor answer
Concur: I generally agree with good responses of drs swamy and rutledge. Radon is a known and significant carcinogen. Furthermore, numerous inhalants, including many products of burning/combustion are considered carcinogens related to lung cancer. Lung cancer like other cancers is closely related to intensity and duration of exposure to carcinogens/injurious substances. Drswamy provided good link. ...Read moreSee 2 more doctor answers
Low, but depends: The overall risk of lung damage resulting in breathing problems is less than 1-2%, but depends on the size of the radiation field, whether nodes are being treated, the technique (2d, 3d, or imrt), use of chemo during radiation (unusual), and issues with the patient (history of interstitial lung disease , etc). Ask your doctor what techniques they will use to reduce the amount of lung treated. ...Read moreSee 2 more doctor answers
Prognosis for untreated stage 3b non small cell lung cancer with low oxygen sats, diabetes, heart disease, high blood pressure, and emphysema.
Low but not zero: Stage ii colon cancer means no lymph node involvement by definition, but inadequate lymph node sampling (surgical resection) may "understage" the cancer, so make sure enough ln were taken -minimum of 12! even with appropriate surgery, mets may still occur, although very unusual, so discuss with your treating docs. A pet/ct may give some reassurance so ask if this can be done. ...Read moreSee 1 more doctor answer
Would lung cancer cause enlarged hilar and mediasternal nodes, GGO on Chest CT and impaired gas exchange. Other lung function tests are normal?
Possibly: There are many different forms of lung cancer however the most common types usually appear as a solitary nodule or mass on CT. GGO can be seen with lymphatic involvement as is suggested by the enlarged lymph nodes described. This can be from infection, cancer or autoimmune diseases such as sarcoidosis and even heart failure. A biopsy of an enlarged lymph node may be required. ...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
