TOXIC METALS AND CANCER
Exposure to heavy metals is considered as a main threat to human health and biological system. Toxic metals and cancer have been widely studied and their effects on human health regularly analyzed by international bodies.
Arsenic (As), cadmium (Cd), chromium (Cr), and nickel (Ni) are category 1 heavy metals according to the International agency for Research on Cancer. Various reports have found that exposure to these compounds leads to disruptions in tumour suppressor gene expression, damage repair processes, and enzymatic activities concerned in metabolism via oxidative damage.
Some studies have indicated that the risk of heavy metal exposure is interrelated with the contamination source. For example, recent studies found an increased risk of occupational disease and cancer in workers in heavy metal-using industrial areas.
Cadmium (Cd), mercury (Hg), lead (Pb), copper (Cu), and nickel (Ni) are among the metals that have potential adverse effects on human health, and chronic exposures to them are nearly unavoidable in daily life, such as from airborne particles, soil, water, and subsequently food.
Recently, certain heavy metals such as cadmium (Cd), mercury (Hg), lead (Pb), chromium (Cr), and arsenic (As) showed a close association to breast cancer. Several epidemiological studies have demonstrated that exposure to metals has toxic and carcinogenic effects on humans and animals.
Toxic metals and cancer has been well studied and these heavy metals are confirmed as human carcinogens; lead, cobalt, and iron are observed as potential carcinogens. Prostate cancer mortality was found to be strongly contributed to cadmium (Cd), followed by zinc (Zn) and chromium (Cr). Excess occupational and environmental exposure to metals is considered to be a major cause of metal-related cancer and also associated with increased cancer risk.
Aluminum exposure has been strongly correlated with carcinogenesis in the breast tissue. Mice subjected to AlCl3, the same aluminum salt used in antiperspirant deodorants, displayed malignant growth of mammary gland epithelial cells. This same result was observed in studies performed on samples of human breast cells. This heavy metal was also hypothesized to have a role in the development of sarcomas.
This heavy metal has been detected in an extensive variety of malignant growths. Research strongly supports role of arsenic in the development of lung, bladder and skin cancer. Another study determined a strong positive association between exposure and mortality rates of cancers including colon, gastric, kidney, lung and nasopharyngeal. Epidemiological studies have also suggested an association between chronic low-level exposure to arsenic and development of pancreatic cancer and non-Hodgkin’s lymphoma.
Furthermore, an increased risk of lung cancer was observed in individuals exposed to exceptionally high concentrations of beryllium, which suggests that this element does induce some carcinogenic mechanism. The use of beryllium in the dental industry creates additional occupational risk for exposure. It was determined that the use of protective equipment significantly reduced the level of exposure in individuals. Additionally, elevated concentrations of beryllium were detected in patients with stage III breast cancer. However, beryllium was one of several heavy metals detected, so a defined role has not been identified at this point. Exposure to beryllium is also recognized as a risk for the potential development of osteosarcomas.
Exposure to cadmium has been associated with carcinogenesis in multiple tissues including breast, oesophagus, stomach, intestines, prostate, lungs and testes. Cadmium also has a proposed role in the development of cancer in the gallbladder.
Along with cadmium, lead was detected in significantly higher concentrations in glioma patients, suggesting these two metals combined may produce excessively toxic effects. One study has determined strong correlation between lead exposure and the development of kidney cancer. Another study concluded that patients with higher levels of blood lead had an increased risk of developing renal cell carcinoma. Lead was one of several heavy metals observed in statistically higher concentrations in gallstones.
Although a causal role has not been established at this time, it has been proposed that mercury exposure may be associated with renal cancer due to this organ being a target for this element. Another study observed that increased mercury exposure has been correlated with liver cancer, and it also has the carcinogenic potential to induce gastric cancer. Mercury was another heavy metal detected in gallstones in statistically higher concentrations from patients with gallbladder cancer. A causal association was not observed with this metal, but a role in carcinogenic development was hypothesized.
There are a variety of cancers that have been associated with nickel exposure. Epidemiological studies have revealed a significant correlation between exposure and the incidence of carcinogenesis in lung, nasal and sinus tissues. In another study, high levels of serum nickel were determined to be statistically significant in patients with breast cancer, suggesting that exposure has potentially carcinogenic consequences. Exposure to this heavy metal has also been associated with the development of acute myeloid and lymphoblastic leukaemia.
Toxic metals and cancer has been well documents, even though there is much more work to do in this important field.
CHECK YOUR HEAVY METAL LEVELS
If you have concerns about your level of heavy metals there is now a simple Hair Tissue Analysis that you can do to determine a number of heavy metals that are circulating in your blood, as well as a full mineral profile.
ELIMINATING HEAVY METALS NATURALLY
Reading this article, one can conclude that heavy metals are everywhere and very difficult to completely avoid these days – however careful we are with our food choices. The relationship with cancer which is a huge cause of death is also interesting.
In order to prevent free radical damage from toxic metals, it is important to undertake a natural toxic metal detox. The question, is what is the best choice as there are so many detox products on the market?
