No, it does not necessarily mean that cancer has spread to your lungs. There are other things that can cause such things. Do you live in the mid-West? Were you raised on a farm? There are fungal infections that are just one thing that can cause something like this.
I know it is hard to be patient, and I would be worried too...who wouldn't....but do try to be calm and wait for a definitive diagnosis.
