🫁Did you know that the link between smoking and lung cancer was established through a large-scale long-term study similar to the Manitoba Tomorrow Project?
The British Doctors Study led by Sir Richard Doll and Sir Austin Bradford Hill began in 1951. Doll and Hill sent a questionnaire to all registered British doctors, more than 40,000 of whom replied providing demographic information and outlining their smoking habits. Throughout 50 years of follow-up, Doll and Hill observed strong evidence of a direct link between smoking and mortality from lung cancer.
Similarly, the Manitoba Tomorrow Project is a longitudinal study, meaning the same participants will be followed over many years. By collecting data and biological samples (e.g., blood, urine, stool) from participants over time, longitudinal studies capture changes that occur following exposure to various risk factors (e.g., smoking, diet, physical activity, work-related hazards). Cancer and chronic diseases take a long time to develop, so longitudinal studies provide researchers with the ability to better understand how things that occurred years before a diagnosis contributed to the development of a disease. These discoveries could fuel improvements in disease prevention, detection, and treatment.
We believe the Manitoba Tomorrow Project has the potential to support groundbreaking health research for decades to come. Thank you for making this possible!
