What happens in Part II of When Breath Becomes Air?
Part II opens with Paul Kalanithi stepping from the role of physician to that of patient—a shift he has long witnessed in others but now experiences himself. After receiving his terminal lung cancer diagnosis, Paul faces the choice of whether to return to neurosurgery. He opts to operate again, motivated by a desire to see what his hands and mind can still achieve. His oncologist, Emma Hayward, plays a quiet yet crucial role, adjusting his treatment to allow him to continue working. Meanwhile, Paul and his wife Lucy navigate the fractures in their marriage, grappling with the pressing question of whether to have a child. They decide to conceive, and Lucy becomes pregnant—a choice Paul views not as a denial of death but as a celebration of what life, even if brief, can encompass. The chapter shifts between the operating room, the clinic, and the couple's home, highlighting Paul's physical decline alongside his unwavering surgical skill. He completes a fellowship, publishes his work, and begins crafting this memoir. As his cancer worsens and he can no longer stand at the OR table, he ultimately sets down the scalpel for good, turning fully to writing as his remaining tool.
Analysis
Paul Kalanithi structures Part II around a poignant irony: the neurosurgeon who dedicated his life to understanding the boundary between life and death now finds himself on that very edge. The chapter's title—taken from a poem by Carew—marks his transition from being the one who alleviates others' suffering to becoming someone who must confront his own end. Kalanithi's writing captures this duality: clinical terms like "T790M mutation" and "erlotinib" coexist with lyrical reflections, ensuring that neither voice overshadows the other. This choice is intentional—the scientific language isn't just cold jargon; it's a form of honesty, the very way Paul has always made sense of the human body.
The decision to have a child with Lucy serves as the chapter's emotional and moral pivot. Instead of romanticizing the choice, Kalanithi questions it: "Will having a child make your death more painful?" Lucy asks. His response—that it will also add meaning to his life—reconfigures the entire memoir's perspective on time. A shortened future is not devoid of value.
Emma Hayward acts as a structural reflection: she navigates Paul's dying much like Paul once managed his patients', with careful honesty and restrained certainty. The scenes in the operating room carry a somber weight—each surgery could be his last—while the memoir-writing that concludes the chapter portrays language as the final act of healing: diagnosing, witnessing, and leaving behind something whole for those who remain. The shift in tone from urgency to acceptance unfolds gradually, without any clear announcement.
