No longer viewed solely as a genetic disease, cancer is increasingly understood as a condition influenced by modifiable lifestyle factors. The American Cancer Society states that an estimated 40 percent of all cancers in the United States are associated with potentially modifiable risk factors, including obesity, poor diet, and physical inactivity.
In a Vital Signs interview, Dr. Jason Fung, bestselling author of “The Cancer Code,” challenges the traditional gene-centric view—instead pointing to a complex interplay between cellular function and environmental factors. He advocates for strengthening the immune system and improving the body’s “cellular soil” through lifestyle changes, particularly diet, as a major tenet of cancer prevention.
