c. Diabetes MellitusChildren who developed IDDM in New South Wales, Australia were matched with healthy children (ratio 1:2) of the same sex and age for comparison. Those who were exclusively breastfed during their first three months of life had a 34% lower risk of developing diabetes than those who were not breastfed. Children given cow's milk-based formula in their first three months were 52% more likely to develop IDDM than those not given cow's milk formula.

d. Childhood CancerChildren who are artificially fed or breastfed for only 6 months or less, are at an increased risk of developing cancer before age 15. The risk of artificially fed children was 1-8 times that of long-term breastfed children, and the risk for short term feeders was 1-9 times that of long term breast feeders.
