Cadmium is a bluish white metal, like zinc and toxicity similar to that of mercury. Humans assimilate cadmium through food. Naturally, large quantities of cadmium are released into the environment. Half of this cadmium is released into the rivers through the decomposition of rocks, also is released into air through forest fires and volcanoes.

Cadmium release fertilizers on crops, the rain that attach to the land. Whole grains, potatoes, some vegetables or shellfish are important sources of cadmium.

Now, a study by Karolinska Institute Sweden’s strengthens the connection between environmental pollution and the data of increasing incidence of breast cancer. The idea is that women whose diet contains high levels of cadmium have an increased risk of developing breast cancer.

The research team observed 55,987 women over 12 years, assessing dietary exposure to cadmium through a questionnaire. During the monitoring period, the researchers found 2,112 cases of breast cancer.

The overall group was divided into 3 subgroups in relation to exposure to cadmium: the set with greater exposure to cadmium through the diet was associated with an increase of 21% risk of developing breast cancer.

The study (published in Cancer Research) found that women who consumed higher amounts of vegetables and whole grains still had a lower risk of developing breast cancer than women exposed to cadmium through the intake of other foods.

The authors of the study are shown highly concerned about the contamination of agricultural land by the increased use of fertilizers and the subsequent absorption of metals by plants.
