An excerpt from “A Return to Healing” explores the intricate nature and false beliefs associated with cancer screening. Patients frequently seek extensive tests to eliminate the possibility of cancer or other serious conditions, a procedure referred to as screening—designed to detect problems before symptoms manifest. Many credit their survival to early diagnosis by attentive physicians.

The book classifies cancers into “birds,” “rabbits,” and “turtles.” “Birds” represent aggressive cancers, such as ovarian and pancreatic, that evade life-saving interventions through early detection. “Rabbits,” like breast cancer, can gain from early identification, although the advantages are often limited and come with the risk of harm. “Turtles” are slow-growing cancers that seldom affect lifespan, yet screenings frequently misguide patients into unnecessary and damaging treatments, as exemplified by instances of prostate cancer.

Prostate cancer screening highlights shortcomings in present medical methodologies. Although it identifies a primarily non-lethal type of cancer, treatments can significantly diminish quality of life, as seen in Mr. D, who experienced severe side effects after treatment without any symptomatic relief.

The excerpt underscores systemic challenges, where an emphasis on measuring and remedying conditions neglects the damage inflicted by over-treatment. It critiques a healthcare culture that favors metrics over patient-focused care, calling for a reassessment of screening practices to prevent needless harm and concentrate on authentic health advancements.
