Can one chest CT cause harm to the cells or soft tissue of the lungs? Is cancer possible? I m 30yr old male.

Doubtful: Cumulative radiation exposure is known to induce cancers, but 1 ct scan is not alot of radiation, relatively speaking, though it may equal the amount of radiation exposure of several hundred chest x-rays. Be your own advocate if confronted with a recommendation that you undergo repeated ct scans. ...Read more

Can one chest CT scan damage lung and cause lung cancer ?

Can one chest CT scan damage lung and cause lung cancer ?

Not likely: The natural exposure one might get just from where you live may exceed 3msv per year. Living in denver, you might be exposed to 6msv per year. Risk of developing cancer from a properly conducted ct scan is low. I believe the estimated average radiation exposure for a single chest ct is about 5-7msv. A low dose chest ct is about 2msv. ...Read more

Had a early cdt lung blood test only one that was just barely elevated was the mage4. I have also had chest CT scan that was normal . This means what?

Had a early cdt lung blood test only one that was just barely elevated was the mage4. I have also had chest CT scan that was normal . This means what?

Were they: Looking for a blood clot, or pulmonary embolus, in the lung? If so the ct scan should rule it out but wait for better advise! i'm not sure what a cdt lung blood test is nor the mage 4 but that was probably the screening test to get the ct which was negative. Wait for a better opinion but the ct, i'll bet, ruled it out. I'm gonna try to refer you to a genius pulmonary guy in my online network. ...Read more

Hi docs, can you tell me if small nodes seen on lungs thru chest CT scan are suggesting lung cancer?

Hi docs, can you tell me if small nodes seen on lungs thru chest CT scan are suggesting lung cancer?

If there are multiple nodules, this actually may be related to infection. One example of such an infection is TB. If you have smoked in the past, swollen lymph nodes on the chest CT, or signs of illness, this raises the risk for a malignancy. ...Read more
