These are benign conditions.
Thanks for writing to us
in lungs may be due to many reasons like sequel of infection,chronic exposure to some irritants present in air like coal dust,silica etc.
You don't worry.It is a benign finding and it shows healed stage.It is not active at all.This condition doesn't require any treatment unless it is severely compromising lung functions.
Micronodule in RLL may also be due to many reasons like infection,inflammation,hamartoma
etc.Mostly these are benign conditions and doesn't require any treatment.However you can have follow up X-ray for increase in size.It also need clinical corelation.
Get well soon.
