Cancer Prevention and Lifestyle

Kerry Courneya: exercise reduces cancer risk and substantially improves outcomes in cancer patients

Kerry Courneya

“Exercise epidemiology shows a clear dose-response relationship between physical activity and reduced incidence of at least 13 cancer types, with the strongest evidence for colon, breast, and endometrial cancers. For cancer patients, exercise during treatment reduces fatigue, maintains muscle mass, and appears to improve chemotherapy tolerance and survival outcomes in randomized trials. The mechanisms include reduced circulating estrogen, insulin, and IGF-1; improved natural killer cell activity against tumor cells; and systemic anti-inflammatory effects. Exercise is increasingly recognized as medicine in oncology.”

Ruth Patterson: time-restricted eating reduces cancer-promoting metabolic factors and improves outcomes

Ruth Patterson

“Epidemiological and clinical data link night-time eating and short overnight fasting windows to increased cancer risk, particularly breast cancer. Ruth Patterson's research shows that women who fasted fewer than 13 hours nightly had significantly higher risk of breast cancer recurrence compared to those fasting 13 or more hours. The mechanism involves reduction of circulating insulin and glucose during the fasting window, which limits the metabolic substrate available for tumor growth. Aligning eating patterns with daytime circadian biology reduces cancer-promoting insulin signaling and improves metabolic biomarkers.”

Kerry Courneya: resistance training during chemotherapy preserves muscle mass and improves treatment tolerance

Kerry Courneya

“Cancer-related muscle wasting (cachexia) is a major predictor of treatment failure and mortality. Randomized trials by Courneya show that supervised resistance training during chemotherapy for breast cancer significantly preserved lean body mass, reduced treatment-related fatigue, and improved completion rates of the full chemotherapy course compared to controls. Higher muscle mass correlates with better drug pharmacokinetics and reduced toxicity. These findings have contributed to oncology guidelines recommending exercise as a standard component of cancer care rather than rest and inactivity.”

Rhonda Patrick: cruciferous vegetables and sulforaphane neutralize carcinogens through NRF2-driven detoxification

Rhonda Patrick

“Daily exposure to environmental and dietary carcinogens creates a chronic burden of DNA damage that initiates cancer when repair systems are overwhelmed. Sulforaphane from broccoli sprouts activates NRF2, which upregulates phase II detoxification enzymes — including glutathione S-transferases and NQO1 — that conjugate reactive carcinogens for elimination before they can damage DNA. Epidemiological studies consistently show inverse associations between cruciferous vegetable consumption and lung, colorectal, and bladder cancer risk, with the strongest effects in individuals with polymorphisms that reduce endogenous detoxification capacity.”
