  • The evidence indicates that of all cancer-related deaths, almost 25–30% are due to tobacco, as many as 30– 35% are linked to diet, about 15–20% are due to infections, and the remaining percentage are due to other factors such as radiation, stress, physical activity, environmental pollutants etc.
