Susannah’s Diagnosis and Initial Treatment
Colorectal Cancer and Early Findings
Susannah’s storyline centers on a recurrent battle with colorectal cancer, beginning years before the main timeline with a diagnosis that brings uncertainty and urgency to the Fisher family. Early symptoms and a colonoscopy lead to biopsy results that shift the family’s focus to treatment and future planning. This section outlines the medical steps and emotional fallout that frame her ongoing health journey.

Surgical Procedure and Recovery
Susannah undergoes a colectomy to remove the cancerous section of her colon, marking a pivotal moment in the series. The books and show depict hospital stays, pain management, and the slow process of returning to daily activities. Family members take turns providing support, and Belly begins to grasp the long-term implications of living with cancer history. Recovery scenes highlight vulnerability, dependence, and the practical challenges of post-surgical life.
Relapse, Further Treatment, and Fertility Concerns
Recurrence and Additional Surgeries
After initial remission, Susannah experiences a recurrence, leading to further surgeries and ongoing medical interventions. The narrative does not specify exact timelines or medical details but emphasizes the cyclical nature of treatment and the emotional toll of repeated hospital visits. Each relapse reshapes family dynamics, particularly between Susannah, Conrad, and Laurel. The show and books use these beats to explore how uncertainty reshapes milestone decisions such as marriage and parenthood.
Potential Impact on Fertility and Long-Term Health
Colorectal cancer and its treatments can affect fertility, and the storyline addresses concerns about future childbearing. While explicit medical details are often implied rather than explained, characters discuss the possibility that surgeries and chemotherapy could influence Susannah’s ability to have children. This topic adds another layer of complexity to her decisions about marriage, career, and quality of life, reflecting real-world considerations for young cancer survivors.
Narrative and Emotional Impact on Key Relationships
Relationship with Conrad Fisher
Susannah’s illness profoundly affects her marriage to Conrad’s father, creating a backdrop of stress, grief, and caregiving in the Fisher household. Conrad balances loyalty to his mother with his own emotional needs, and his romantic relationship with Belly is often influenced by the presence of his family’s health crisis. The books and show depict moments of strain, tenderness, and sacrifice as Conrad navigates loving both his mother and his partner amid ongoing uncertainty.
Connection with Belly Conklin
Belly’s evolving understanding of Susannah’s condition shapes much of her personal growth across the series. From childhood glimpses of her mother’s fatigue and hospital routines to later conversations about mortality and love, Belly learns how to support Susannah while managing her own feelings. The tension between staying present for her friend and acknowledging the emotional weight of illness is a recurring theme in pivotal moments between them.
Show Versus Book Storylines
The TV series adapts and condenses Susannah’s storyline, often combining timelines and altering the pacing of her relapses. Showrunners emphasize visual storytelling around hospital scenes and family reactions, sometimes compressing the emotional beats that the books spread across multiple years. While the core events—diagnosis, surgery, recurrence, and grief—remain consistent, details such as specific treatments, timelines, and conversations may differ between mediums. Viewers and readers should note these variations when comparing the series to the source material.
