Lung Cancer

CT scan of 5mm nodule



Three months ago a scan showed a few 4-5mm lung nodules on right lower lung. I had a ct scan with contrast today and waiting for results. Will contrast determine if they are cancer? Also, can a CT technician see if its cancer while he is administering the scan? I`m freaking out trying to read into his actions and words after my scan. HELP! I`m 46, 1/2 pack smoker for 20 years. Quit in Jan.!


A 5mm nodule is likely not cancer, but needs to be followed with serial CT's.  Contrast does not help determine if the nodule is cancer and I usually get CT's without contrast.  The tech cannot tell anything while doing the scan as they are not trained to read them.

I hope this helps and congratulations on stopping smoking.
