If lung cancer is contained to both lungs is it still considered Stage 4? My mom's doctor just ran a PET Scan and confirmed other suspicious areas outside her lungs are negative or benign - does that change her diagnosis? They didn't mention...

Lung Cancer Support
A tumor that has spread to the other lung is considered a stage 4.
Other factors that affect a stage 4 diagnosis are:
Size of primary. If it’s 7cm or larger it’s considered stage 4.
If there’s 2 or more separate nodules in different lobes of the same lung.
It’s not considered metastatic disease unless there is a nodule outside the lung.
