Cadmium in diet may increase breast cancer risk
11 June, 2012
DENMARK: Ingesting higher levels of cadmium, a metal found in fertilizers, may be linked to an increased risk of breast cancer, a new study from Sweden suggests. The results showed that postmenopausal women with a relatively high daily dietary cadmium intake had a 21 percent increased risk of breast cancer. The major sources of cadmium in the diets of women in the study were foods that are generally healthy — whole grains and vegetables. These accounted for about 40 percent of the cadmium consumed. The reason for the link may be that cadmium can cause the same effects in the body as the female hormone estrogen, the researchers said. Estrogen fuels the development of some breast cancers. Whole grains and vegetables generally protect against cancer, and people should not avoid these foods because of this study, said study researcher Agneta kesson, associate professor at Karolinska Institute in Sweden.
