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

What is a lung nodule?

What is a lung nodule?

X-ray spot: It can be anything from an old inactive walled-off TB of fungus infection to a benign tumor to cancer to something as exotic as a dog heartworm that went far astray. Here in kansas, most are old histoplasmosis. But a spot is lung cancer until you & your physician have a reason to think otherwise. Good luck, and be brave. ...Read more

What is a lung nodule?

Solid mass in lung: A lung nodule is a soft tissue mass that is located somewhere within the lung itself. It can be a benign or malignant nodule. Following it with ct scans to see if it changes in size is one way to manage them or going directly to biopsy. ...Read more

What are the tests for lung nodule?

What are the tests for lung nodule?

Many options: Depends on age, size of nodule, history, and smoking history. Options include do nothing (rare), pet scan if there is risk for cancer, follow up cts at intervals determined by experienced md. Biopsies and surgery can come, but generally after above steps. Most nodules (>95%) are not cancer, and therefore invasive procedures should be reserved for when suspicion (guided by above factors) is high. ...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

What does a lung nodule indicate? How is it treated?

What does a lung nodule indicate? How is it treated?

Usually nothing: Most people, if you go looking, have lung nodules and most are benign scar-like reactions in the lung, and therefore they don't need to be treated any more than a freckle or mole on your skin needs to be treated. Just like moles, some lung nodules (<4% in high risk people) can be cancer and should be followed to see if they change. ...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 do you recommend if I have a 13 mm lung nodule, is that big?

What do you recommend if I have a 13 mm lung nodule, is that big?

Big enough: A 13 mm lung nodule warrants a pet/ct scan. This will identify things like calcifications seen in benign nodules and will determine if sugar uptake is high as seen in infection or tumor or low indicating scar. Depending on the likelihood of cancer, a ct guided biopsy is possible in most peripheral nodules greater than 9mm. Lung cancer is increasing in nonsmokers, women and the young in u. S. ...Read more

Going for followup 2mrow. Worried abut mu lung nodule. Scared too, . .

Relax: Sometimes, we as physicians use that word loosely. I did not mean to be lackadaisical. I am sure you are concerned and I am only trying to calm you down. I see you have other conditions being followed by your doctor. Have a good talk with your doctor as to the best way of finding out and options of treatment. Lung cancer is very rare at your age anyhow. ...Read more

Do you believe that absestos can cause a lung nodule?

Dr. Paul Velt Dr. Velt
3 doctors agreed:
Do you believe that absestos can cause a lung nodule?

Yes: Is the short answer. Asbestos can cause several different changes to the chest and lung fields. Pulmonary nodules are just one example. Pleural disease including plaques and calcification as well as mesothelioma are side affects of asbestos. Lung cancer is also a problem. Don't ignore this nodule. Talk to your doctor. ...Read more

Saw a show on tv and they mentioned something called lung nodule. What is that?

Also used to be: Called a coin lesion. A solitary pulmonary nodule may be a primary cancer, or a granuloma or other benign things like a hamartoma or interlobar node. It also may the cause of "false positives" on ct-chest screening. Multiple nodules draw suspicion to traveled tumors. When very small (<5 mm), can be watched for growth; if larger, further work up including removal. ...Read more

I have a 4mm lung nodule on my right lung 2 on my left could it be cancer?

Maybe....: ...maybe not. If they are all less than 5-6 mm, there is usually not a whole lot to do other than observation and follow up. PET scans are usually not too sensitive for very tiny nodules. I would defer, however, to the judgement of your physician who knows your situation better and can determine if there is anything else to do now. If you smoke, please stop. Best to you. ...Read more

What is the lowest intake suv on a pet scan (lung nodule)?

What is the lowest intake suv on a pet scan (lung nodule)?

Zero: The lowest suv (standardized uptake value - a semiquantitative measure of metabolism) is zero.

The maximum suv in a region of interest is called suv max.

Generally, if the lung nodule is less than an suv max of 1, it is likely benign. However, there are plenty of non malignant diseases that can have increased FDG uptake, such as healing fungal lung infections, called granulomas. ...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
