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

Fell on my back, had cat scan, revealed (2) 4mm lung nodule pulmonary doctor says I should have nothing to worry about, follow cat scan in 6 mnth?

Probably overkill: For nonsmokers, with nodules in that size range, we recommend no further follow-up. If you are smoker, stop smoking. If any follow-up is necessary, 12 months is probably all you need. ...Read more

Is an 8mm lung nodule followed up by another scan?

Is an 8mm lung nodule followed up by another scan?

Almost always, yes: Depends on your history and the appearance/location/shape of the nodule, but most often a follow up CT scan is the most appropriate test. Occasionally, if your doctor is concerned a PET scan may be useful for 8mm, but if its negative it is less helpful than when you have a larger nodule, for which PET is more reliable at excluding the likelihood of cancer. ...Read more

It is very likely that a 2.6cm lung nodule presents symptoms?

It is very likely that a 2.6cm lung nodule presents symptoms?

Unfortunately, no: Lung cancers are often diagnosed quite late because patients may not have symptoms for a long time. Eventually, people will have a cough, cough up blood, lose weight, have chest pain or shortness of breath. If a nodule is benign, the presence of symptoms probably depends on the exact location (whether it blocks an airway, for example). ...Read more

What should I do for a lung nodule found on right lung?

What should I do for a lung nodule found on right lung?

Get it TNM staged.: If there is a lung nodule, and it appears solitary, it still needs to be evaluated to see if there is no metastasis, etc. Ct scan and an ENT (ears, nose, and throat) exam are done. The ct helps determine if there is lymph node involvement. An aspiration biopsy of the lesion can be taken to determine its histology. Surgical resection in localized cases is done for all types except small cell. ...Read more

What are the symptoms of a lung nodule and are they malignant?

What are the symptoms of a lung nodule and are they malignant?

No symptoms: Lung nodules have no symptoms, unfortunately. Most of the time, they are benign things like scars, but sometimes they can be early cancers. If you have a nodule found on a cat scan, they need to be followed to make sure they don't grow or change over time. This is especially true if you have risk factors for cancer such as smoking or radiation exposure. ...Read more

Difficult to explain: Tumors, primary or metastatic tend to grow more rapidly, may be associated with weight loss, positive positron scan, malignant cells in sputum, fine needle aspirate or on biopsy. Often the distinction is difficult. ...Read more

Lung nodule grew 6mm, could I have cancer?

Lung nodule grew 6mm, could I have cancer?

50%: A non calcified lung nodule has a 50%risk of being cancer. Diagnosis of cancer is made by pathologist on a microscopic slide of a significant biopsy size. Removal of the whole nodule provides the pathologist with adecuate specimen. Needle biopsy of a lung cancer will miss the diagnosis half the time. So if it is cancer by needle bx it is. Otherwise undiagnostic. ...Read more

Will a 6mm lung nodule show up on a pet scan?

Maybe: Lung nodules smaller than 10 mm (3/8 inch) can be falsely negative on pet because of limitations of the technology. That means the uptake on the scan is not high enough to be suspicious even though the nodule is actually worrisome. However, some small nodules have enough uptake despite their small size. The pet is not a bad idea for a 6 mm nodule, and if positive, means aggressive evaluation. ...Read more

Can a biopsy be taken of a calcified lung nodule?

Can a biopsy be taken of a calcified lung nodule?

Yes, but: Calcification of a lung nodule frequently indicates that it is benign in nature. It is the noncalcified nodules that are most concerning for lung cancer. And thus the noncalcified nodules that more frequently meet criteria that prompts biopsy of the nodule. Appropriate treatment of lung nodules is best done at facilities with experience ...Read more

What are the odds that a lung nodule is cancer?

What are the odds that a lung nodule is cancer?

It depends: Not all lung nodules are alike. The odds that a nodule is cancer depends in the appearance and size of the nodule, the medical history of the patient, the smoking history of the patient, and how the nodule changes over time. Radiologists, pulmonary physicians and thoracic surgeons are best qualified to determine the risk that a particular nodule is cancer. ...Read more

Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more


Nodule (Definition)
