My grandfather 73/m is a cancer survivor. Recently they found he had a cavitary lesion in his right lung. Is it a sign that the cancer is back?

Possible: This is very likely. The other possibility is infection. He needs to be seen rather quickly to determine the cause and get the proper treatment. ...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

Smelly sputum with 39.5 degrees c. & chest X-ray showing left basal cavitary lesion. What does this mean? What is this diagnosis?

Different causes: With infection in lungs cavitary lesions can be seen with granulomatous disease such as TB, fungi, or coccidiodomycosis (valley fever). Staph infection and other bacteria can have cavitation. Metastases and neoplasms also can have necrosis or cavitation. ...Read more

What is infectious granuloma auch as tuberculosis verus cavitary lung cancer?

What is infectious granuloma auch as tuberculosis verus cavitary lung cancer?

Unclear question: Examination of the tissue by a pathologist is the gold standard for diagnosis. However, an apical cavitary lesion in the lung should be treated as tuberculosis, unless proven otherwise.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

Can multiple lung lesion 2.5cm in size be detected on routine chest x rays?

Can multiple lung lesion 2.5cm in size be detected on routine chest x rays?

Yes: The resolution of the cxr is such that it should be able to show lesions this big. The advent of the digital xr even makes it easier to see them. It still does not give us the diagnosis, it only makes us see them so we can work them up. ...Read more

If there is a lesion or more in my lung and its too dangerous for a biopsy because of air pockets surrounding it how will they know if its cancerous?

If there is a lesion or more in my lung and its too dangerous for a biopsy because of air pockets surrounding it how will they know if its cancerous?

Biopsy: The specifics of location and anatomy will have an impact. Additionally degree of disease in your lung will impact risk of biopsy. That said, if too risky for radiology guided biopsy, you may be a candidate for inreach/em-navigation bronchoscopy with biopsy. Again, risks greatly depend on your overall health, location of lesion, and conditions of lung/pulmonary status. ...Read more

The dr said I have a lung lesion from previous pneumonia.. Its white and perfectly round. Can this be cancerous. I'm worried but the dr didn't seem to b?

Possible: But not necessarily, we often find lesions on x rays and ct scans which are not cancerous and amenable to follow up with serial imaging; however, certain radiographic features and size may warrant further investigation with pet/ct or biopsy; I suggest you discuss the findings on your imaging with a pulmonary specialist. ...Read more

Chill: Your question is a bit confusing but as I understand you are going to have a biopsy, no? I know it's easy to say but please chill until you get the results. It may be benign.

Please explain: 5 CM irregular splenic lesion. Differential diagnosis lymphoma and splenic metastasis. Could this be cancer?

Yes: Both are forms of cancer. It could also be a benign hemangioma, an epidermoid cyst, an infart (how's your overall vascular health?) or any of a number of other entities. What to do next will depend on your history and physical exam. You're in no immediate danger but this very much needs to be followed up. Many of the lymphomas especially are very curable with today's biotech. ...Read more

What is the prognosis for lung cancer with a lesion in the brain?

What is the prognosis for lung cancer with a lesion in the brain?

Likely poor/bad.: A lung cancer with a lesion in the brain is considered stage IV as this means that there is distant metastasis. This has a 5 year survival of < 5%, so you can see that the chances of successful therapy are very small. But take heart, for therapy has come a long way and depending on the type, like small cell cancer, chemotherapy can stop even extensive cases. So see your dr. B/c you never know. ...Read more

Had a CT scan and showed a large bullous lesion on left lung how can this be treated?

Wow: This is a tough issue. It will need the discussion of several lung specialists to find the right option. Vats bullectomy and watchful waiting with bronchodilators are options.

Stay away from er, they tend to put in chest tubes because they think this is a pneumothorax. In asymptomatic patients it is best to not perform surgery.

You must see a lung doc. ...Read more

Dr found a very small lesion on my lung, I worry about it but he said its so small we don't need a CT scan. How do I ease my mind?

Dr found a very small lesion on my lung, I worry about it but he said its so small we don't need a CT scan. How do I ease my mind?

Small lung lesion: Most very small lesions/spots/nodules seen on chest x-ray are benign temporary findings or calcifications. The usual recommendation is for repeat x-ray in 1 year, or perhaps 6 months if you have risk factors (smoking, risk of TB or other lung infection). if there is change, such as increased size then a CT scan may be appropriate. Again most of the small findings on CXR are benign. ...Read more

Discuss: It is important you discuss this condition and your concerns with your thoracic surgeon. You and your surgeon need to have an honest and open discussion of the risks and benefits of all treatment options from observation, biopsy, and surgery. There are modern techniques to allow minimally invasive approaches. But, you and your thoracic surgeon must partner on what is best for you. ...Read more

CT scan of lungs (to rule out clot) showed 15mm lesion on sternum, well corticated. Do I need this monitored or further tests?

If it were me, I--: --would. I would want an MRI bone scan. This would give me an idea if solid or cystic, also the nuclear scan would tell me if it is active, ie: destroying bone. The scan would tell me if there is increased bone uptake, meaning the bone is actively being repaired. If @ all suspicious, have it removed. ...Read more

Hello I have been diagnosed with a small module on my left lower lung. A low density lesion on my liver and a 6mm nodule on my right thyroid lobe.?

See below: Such multiple findings as you describe are not uncommon on various imaging studies such as CT scans of the chest, abdomen, pelvis that include the thyroid, lung, liver, and kidneys where small sub-centimeter (<10 mm) nodules are commonly noted which are most often benign and clinically insignificant but which often deserve a follow-up study in 6-12 months. You should discuss this with your doctor. ...Read more

If a ill defined lesion on liver is seen on cat scan an have stage 3 lung cancer 3 yrs. Out with surgery is it cancer?

Hard to say: The answer really depends on how the CT was performed. In view of the history you provided, it is a possibility. If CT was performed without contrast, then one should be done with. MRI is also a good way to image the liver. In this situation, sit down with your doctors to clarify what is happening. Best wishes ...Read more
