“Dr. Rhonda Patrick reviews observational studies associating physical activity before and after a cancer diagnosis with better survival. These cohorts cannot prove that exercise caused the survival difference because disease severity, treatment, and overall health influence activity.”

“Exercise plans during cancer care can be adapted to the cancer type, treatment phase, symptoms, and individual capacity with support from the oncology team. This clip is excerpted, with permission, from Dr. Rhonda Patrick's appearance on The Rich Roll Podcast.”

“For people who do not smoke, are not heavy drinkers, and are not living with obesity, Dr. Courneya places regular exercise next. Physical activity is associated with lower risk for several cancers, including breast, colon, endometrial, kidney, bladder, esophageal, and stomach cancers.”

“Among 25,241 adults who reported no structured exercise, approximately three brief bouts per day totaling a median of 4.4 minutes were associated with lower all-cause, cancer, and cardiovascular mortality.”

Dr. Patrick covers vitamin C's diverse aspects: bioavailability, immune function, viral protection, lung health, cancer impact, exercise effects, and more!

“Research in animal models shows that exercise can even direct immune cells to infiltrate tumors, potentially slowing their growth by up to 60%. In human cancer patients, regular exercise is associated with stronger immune function and improved responses to immunotherapy.”

“Dr. Courneya explains that exercise can increase blood flow through a tumor, potentially improving drug delivery and oxygenation. Better oxygenation is especially relevant to radiation because well-oxygenated tumors are more radiosensitive. Dr. Courneya highlights the small EXERT randomized trial in rectal cancer.”

“In a microfluidic model, exercise-relevant high shear stress reduced the viability of several cancer cell lines and damaged highly metastatic breast-cancer cells more than lower, resting-level shear.”

“Taken together, these findings suggest that exercise alters cytotoxic T cells to mediate exercise-induced cancer suppression. Treatment protocols that incorporate exercise might improve outcomes by activating the immune system. Link to full study.”

“HIIT also produced increases in pro-inflammatory cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor. Interestingly, the inhibition of cancer growth was transient, lasting less than two hours post-exercise when inflammatory cytokine levels were high.”
