Bubbles represent the impact of diet, lifestyle and physical activity on cancer risk on a scale from convincing decrease risk to convincing increase risk. The size of the bubbles relates to the number of cancer cases. Aspects that stick out on the upper part of the diagram are physical activity, walking, but also having been breastfed, while the lower end contains alcoholic drinks, processed meat and screen time. Some aspects reappear in different parts of the graphic, since they have different effects on different parts of cancer risk.
