Traces of the metal cadmium, which is commonly found in kidneys, liver, shellfish and mushroom ups the risk of womb cancer by 22 percent, says a new study.
The metal is also found in tobacco and was discovered in high amounts in patients who had the disease.
According to experts from The University of Missouri, smoking doubled cadmium exposure.
The experts further added that while it was not necessary to cut cadmium-containing food from diet, it was important that they be taken in moderation.
Cadmium is said to create hormonal imbalance and goes on to cause rapid cell division.
Lead author of the study professor Jane McElroy went on to add that cadmium is an estrogen-mimicking chemical, and imitates its effects on the body.
The scientist added that cadmium leads to an increase in growth of endometrium, contribution to an increased risk of endometrial cancer or womb cancer.
The five-year study was published in the journal PLOS One.
