They cut out the lobe of lung wherein resides the offending chunk.
I know someone who hurt their shoulder in a bike accident. this person happened to be 76 years old.
He went to the doctor who had him x-rayed. The x-ray technician noticed a shadow near his lung area. The technician suggested a lung x-ray. the doctor agreed. The x-ray showed a malignant growth,
The early discovery of the cancer gave the biker a fighting chance. Hw went in for the operation where they cut out a lobe of his lung. (The third lobe, as luck would have it, on the lung with three lobes [we have five lobes of lungs all together]).
They could find no further sign of Metastization and so he didn’t need radiation nor chemo therapy.
and so my dad is till alive four years after finding the lung cancer (which is generally a death sentence).
