Breast Cancer and Cadmium Toxicity
Is there a Connection to Breast Cancer and Heavy Metal Toxicity?

With the overwhelming tide of industrialisation and the insatiable demand for minerals by industry heavy metal toxicity poses a serious risk to human health. Heavy metals such as Cadmium, Lead and Mercury have been well studied and well documented in regard to causing detrimental health effects.
It’s almost impossible to avoid heavy metals on a daily basis, coming from dietary sources (soil contamination), occupational sources and from the environment. Exposure (or a build-up in the body) is highly connected to an increased risk of cancer development.
It’s no surprise to discover, Cancer is now the 2nd leading cause of death globally according the World Health Organisation. Cadmium is one such metal that represents a serious risk to human and with strong associations to the development of prostate cancer and breast cancer. It’s believed that cadmium causes oxidative stress which alters gene expression and Damages DNA.
Exposure to Cadmium is primarily from cigarette smoke (direct and indirect inhalation) and predominantly dietary sources for non-smokers. The problem with Cadmium is how the metal behaves like oestrogen. Cadmium is a metalloestrogen, which is a class of metals known to mimic natural oestrogens of the body. Surprisingly, Cadmium caused oestrogenic responses in the body affecting the endometrial lining, progesterone receptors, mammary tissue density.
Cadmium’s influence over breast tissue is significant which affects gene expression as well as altering normal tissue development. Of concern is how Cadmium increases tumour cell proliferation, and problematic in hormone dependent cancers. There is a great need for research in this area but enough to warrant a strong a suspicion around Cadmiums role in the development and progression in Breast Cancer.
Specific nutritional interventions are well warranted, in addition to specific chelation strategies as a proactive strategy to increase the elimination of protagonist heavy metals from the body and re-balance trace elements (minerals).
