Research indicates that toxic metals are more prominently found in cancer tissue.

Metals and metal compounds have been used in medicine for several thousands of years. The anti-cancer activities of platinum and its compounds are recognized. The toxicity of other metals is used to 'kill' tumour cells as is discussed in this research paper by Desoize B.: Metals and metal compounds in cancer treatment. Anticancer Res. 2004 May-Jun;24(3a):1529-44. PMID: 15274320.

The cancer prevalence in the Malwa region of Punjab (1089/million/year) is much higher than the national average cancer prevalence in India (800/million/year). In our previous study on hair metal analysis, we located a high metal burden in Punjabi cancer patients and their live-in relatives, suggesting that an excessive metal exposure is a factor in the pathogenesis of cancer. The present study focused on nail metal analysis, a biological material similar to hair. Previously, we had used ICP-MS spectroscopy to confirm high exposures to aluminium (Al), barium (Ba), manganese (Mn), lead (Pb), uranium (U and other metals in the hair of Punjabi cancer patients and their healthy relatives (Blaurock-Busch et al. 2014).
In this study, we used nail metal analysis to confirm the results of our previous study. We compared the nail metal concentration of healthy Punjabis (N=83) with randomly selected healthy Europeans (N=83) and found highly significant differences between the European and Punjabi groups, including the healthy and the cancer groups. In comparison, our European group showed a low percentage (0 to 13%) of pathological values for aluminium (Al), barium (Ba), cadmium (Cd), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), strontium (Sr), titanium (Ti) and uranium (U), while the healthy Punjabi groups showed between 13% and 99% pathological values for these elements.
The greatest metal burden was found in the breast cancer group (N=13), showing 100% pathological values for Al, Fe, Mn and U. This study supports previous research, which demonstrated a significant metal burden in Punjabi people. Water, soil, and phosphate fertilizers may be the cause of this excessive exposure.

The carcinogenicity of arsenic, chromium and nickel has been established, the Division of Cancer Epidemiology and Genetics of the US National Cancer Institute indicates. Some experimental and epidemiological studies suggest that lead, beryllium and cadmium may be carcinogenic to humans. Metals such as antimony and cobalt are potentially carcinogenic, though data is limited.
