Small daily changes can cut cancer risk, says oncologist

Dr. Ruchir Tandon says about 40% of cancers are preventable and that everyday habits— quitting smoking, maintaining a healthy weight, staying physically active, eating fiber-rich vegetables and olive oil, limiting processed meats and alcohol, protecting the skin, and prioritizing sleep—collectively reduce cancer risk. He notes small, sustained lifestyle changes compound over time, and pairing these with age-appropriate cancer screening can significantly shift the odds in favour of prevention.
