The Undying: Pain, Vulnerability, Mortality, Medicine, Art, Time, Dreams, Data, Exhaustion, Cancer, and Care is a 2019 memoir by the American author, poet, and essayist Anne Boyer.

Boyer takes an untraditional approach to the standard illness narrative, by weaving together her personal journey as a patient in treatment with reflections on art and literature, and critiques of capitalism and the medical industry.

Ten days after her double mastectomy she gives a university lecture on Walt Whitman's The Sleepers with surgical drainage bags stitched to her compression dressings.

"[11] Parallels between works mentioned by Boyer, such as, Audre Lorde’s The Cancer Journals, Kathy Acker’s “The Gift of Disease,” and Susan Sontag’s Illness as Metaphor are often evoked in reviews.

"Countering the lonesome desolation of illness that oncological praxis and society's own entrenched custom of segregation work to produce, Boyer strives to address and call into being a collectivity of the sick.
