Related Episodes for What Exercise Can—and Cannot—Do for Cancer Risk and Survival

“Researchers in Dr. D'Agostino's laboratory observed a decreased tumor burden and enhanced survival in animals that were provided a ketone supplement, even if they were fed a high-carbohydrate diet.”

“Activation of this important system of immunosurveillance is a predictor of the long-term efficacy of chemotherapy and may help to explain the complex relationship of autophagy with cancer, wherein the initial suppression of autophagy may help prevent attracting undue attention from the immune system, but may later facilitate ongoing transformation.”

“Autophagy is thought to be part of a coordinated biological process that is important for exposing cancer cells to the immune system, ultimately leading to their weakening and death. However, the relationship between autophagy and cancer is complicated.”

“Dr. Patrick also revises an earlier concern about acrylamide: although roasting can form it, the human evidence she reviews does not show that ordinary coffee intake raises cancer risk, and the overall epidemiology points in the opposite direction for several cancers.”

“Perhaps the most clear-cut examples of cryotherapy’s beneficial effects are observed in the brain, where levels of the hormone and neurotransmitter norepinephrine – responsible for vigilance, attention, focus, and positive mood – increase markedly when the body is exposed to extreme cold.”

“Dr. Candow explains why a hormone change within the physiological range cannot by itself establish a hair effect. A later 12-week randomized trial directly measured hormones and hair-follicle outcomes in resistance-trained men taking five grams of creatine per day.”

“Rather, they fall on a spectrum, ranging from a five-to-one ratio of fats to protein and carbs (typically used in clinical settings) to a more liberalized one-to-one ratio, a type of low glycemic index therapy (commonly referred to as "modified Atkins") that might meet the needs of most healthy people.”

“Aging in tumor tissue is markedly accelerated, however – an indicator of the perturbed metabolic and growth processes observed in cancer. In this clip, Dr. Steve Horvath discusses correlations between epigenetic aging and age-related chronic diseases.”

“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”
