In "Breaking Bad", Walter White is a high school teacher diagnosed with which form of cancer?

In the TV series "Breaking Bad," Walter White is a high school teacher diagnosed with lung cancer. This particular form of cancer, affecting the lungs, was chosen for several reasons. Firstly, lung cancer is one of the most common and deadliest forms of cancer worldwide. Secondly, the choice of lung cancer aligns with the overall premise of the show, where a character facing a life-threatening illness opts to embark on a dangerous and morally ambiguous journey, driven by desperation and a desire to secure his family's future. Furthermore, by having Walter White diagnosed with lung cancer, the show conveys a poetic irony, as he becomes associated with a disease typically attributed to smoking and other harmful habits, highlighting the contrast between his previously law-abiding life and his subsequent descent into criminality.
