In 2025, when several friends were dealing with prostate cancer, I began researching the disease and its treatment. I found myself asking a simple question: What would I do if I received a prostate cancer diagnosis?
I soon learned that prostate cancer is not one disease with one obvious treatment. Depending on the type and stage of the cancer, options can include active surveillance, surgery, radiation, hormone therapy, and newer treatments. Understanding these choices—and their possible benefits and side effects—can be complicated.
I became particularly interested in the relationship between prostate cancer and metabolic health. The work of Boston College professor Thomas Seyfried, who argues that impaired cellular metabolism plays an important role in cancer, led me to explore research on glucose, insulin, ketogenic diets, fasting, and other metabolic approaches.
This section brings together some of the doctors, researchers, organizations, studies, and videos that I have found most useful. I have tried to distinguish between established prostate cancer treatments and promising ideas that are still being investigated.
This is a work in progress, and I welcome comments and suggestions.
