Danish kids must grow up thinking that if she can live till her 70s then smoking can't be all that bad for you.
Daisy has the best doctors at her disposal and they probably detect any abnormalities that surface and nip them immediately unlike us peasants visit the doctors annually or not at all unless we are really sick.
Wouldn't they announce that she's going in for a "procedure"?
Also, not every spot on the lung is operable. She's just been very lucky.
