Cancer (Definition)

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

2mm lung nodule lower left lobe - unrelated CT found it - on 1yr fu it's now 4mm. Any reason other than cancer it would grow? I just quit smoking.

2mm lung nodule lower left lobe - unrelated CT found it - on 1yr fu it's now 4mm. Any reason other than cancer it would grow? I just quit smoking.

Benign possibilities: There are many benign causes of a solitary pulmonary nodule. However, with a smoking history, you probably ought to have it biopsied, if possible, or even removed. This is to be certain that this isn't due to an early malignancy whose removal would likely be curative. Kudos to you for smoking cessation; keep up the good work. Good luck! see a cardiothoracic surgeon for evaluation. ...Read more

I had breast cancer a year ago and had a right mastecnomy. Now they have found pleural nodules in right and left lower lobes 5mm, 4, 8mm, 2, 4mm, 4.5mm should I be worried about lung cancer.?

I  had breast cancer  a year ago and had a right mastecnomy. Now they have found pleural nodules in right and left lower lobes 5mm, 4, 8mm, 2, 4mm, 4.5mm should I be worried about lung cancer.?

While these are: Quite tiny, this appears ominous. It would help to know the facts at dx: tumor size, nodal status; er, pr, her-2-neu status. These would influence probabilities. Some treatment, particularly taxanes, can cause pulmonary findings. Go over this with you team, primarily medical oncologist. ...Read more

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

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

I have a 4x3mm sub plural nodule lower right lobe w/family history of lung and colon cancer. Should I get further testing?

What were you told?: These little nodules are extremely common especially in areas where histoplasmosis is endemic, like my home in Kansas. If you look hard enough, probably a majority of folks have them. Unless your radiologist recommends an attempt at a biopsy, I'd forget about it or as maximum monitor it by imaging. There's really no test except biospy; and it's too small to hit easily with a needle. ...Read more

What are my chances of a nodule on my lung being cancer? 54 years, nonsmoker.

What are my chances of a nodule on my lung being cancer?  54 years, nonsmoker.

Size and growth rate: Lung nodules in the lung — are quite common. They appear as round, white shadows on a chest x-ray or computerized tomography (ct) scan. They're usually about .2 inch to 1 inch in size. A nodule that's 25 mm or larger, is more likely to be cancerous than is a smaller one. If prior image is available comparing sizes to assess the rate of growth will help. Cancer grows faster. ...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
