Doctor insights on: Bronchoscopy And Lung Cancer

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

I have multiple lung nodules with a history of oral cancer. Bronchoscopy was benign, but nodules could not be reached.. Chances this metastatic?

I have multiple lung nodules with a history of oral cancer.  Bronchoscopy was benign, but nodules could not be reached.. Chances this metastatic?

Could be metastatic: Lesions of lung associated with oral cancer is not that uncommon. Higher possibility of such disease in lung would correlate better if cervical nodes had been present initially. Bx is essential to initiate therapy if needed. A PET/CAT could indicate possibility of lung mets. Thorascopic bx would be helpful for deciding on definitive management. ...Read more

Bronchoscopy with biopsy of lung nodules was done, biopsy result shows normal bt bronchial washing shows poorly differentiate cancer, confused?

Bronchoscopy with biopsy of lung nodules was done, biopsy result shows normal bt bronchial washing shows poorly differentiate cancer, confused?

Sample and target: You do biopsy, brushings, and washes to increase chance of diagnosis. Many forms of bronchoscopy biopsies are somewhat blind. Nodules can be tricky to "hit". It is possible to take biopsies that do not "hit the target" or nodule/tumor. It's important that you have a comprehensive thoracic oncology team approach to care for both diagnosis and treatment. ...Read more

Is pneuomonia a symptom of lung cancer?

Sometimes: Some lung cancers cause obstruction of the air passage with atelectasis=collapse and pneumonia as a result. If pneumonia does not resolve with usual treatment, ct scan and followup ct may be indicated to uncover a sneaky cancer. ...Read more

How would you know that you have lung cancer?

How would you know that you have lung cancer?

Imaging and biopsy: Most lung cancers are discovered by imaging studies such as chest x-rays or ct scans. These will show mass lesions that should not normally be present. If such a lesion is detected, then it is usually sampled by needle aspiration or bronchoscopy, and cells or pieces of tissue are studied in a laboratory under a microscope to decide if a malignancy is present and to decide what type the tumor is. ...Read more

What tests are done to detect lung cancer?

What tests are done to detect lung cancer?

Variety: Depends on risk factors. The more risk factors you have the more serious the investigation. Baseline CXR, possibly CAT scan, sputum samples, up to bronchoscopy with washings and possible biopsy or guided needle biopsy for findings. Currently even starting genetic analysis of tumors to help predict response to chemo/radiation. If really worried start with Pulmonologist ...Read more

Can lung cancer be detected through a stethescope?

Unlikely.: Unlikely and not definitively. There are signs that might be picked up for particular tumors that, for instance, caused airway obstruction or pneumonia. But the physical exam should be followed up by a specialist with other modalities, such as an imaging study, bronchoscopy, or a biopsy. ...Read more

How do you test for lung cancer? What kind of tests do you need to have to check if you have lung cancer?

How do you test for lung cancer? What kind of tests do you need to have to check if you have lung cancer?

CT screening: If there is specific lesion, biopsies will need to be obtained. Ct scan is used to screen. Lung cancer is often silent until late. However, there is screening for appropriate candidates to help find it early. The following link may help: http://goo.Gl/oqvsp. ...Read more

Bronchoscopy (Definition)

Bronchoscopy is a procedure to visually examine inside of the airways (trachea, bronchii). This can be done using a rigid bronchoscope or flexible fiber-optic scope. It can be used to obtain samples such as washings (bal) and biopsies for diagnosis. There are also therapeutic interventions ...Read more

Lung Cancer (Definition)

From national cancer institute: "cancer that forms in tissues of the lung, usually in the cells lining air passages. The two main types are small cell lung cancer and non-small cell lung cancer. These types are diagnosed based on how the cells ...Read more
