A new study reported by the American Association for Cancer Research found that selenium, a non-metallic trace mineral found in grains, nuts, and meats may help prevent bladder cancer, especially in those patients at high risk.
Researchers from the Dartmouth Medical School also found a significant reduction in the incidence of bladder cancer in women, smokers and people with cancer related to a specific gene—p53.
Lead researcher Margaret Karagas measured the selenium levels in the toenails of 767 people recently diagnosed with bladder cancer and 1,108 people from the general population. They found that higher rates of selenium were related to a reduction in bladder cancer in women (34 percent), moderate smokers (39 percent) and in those with p53 tumors (43 percent).
“Ultimately, if it is true that selenium can prevent a certain subset of individuals, like women, from developing bladder cancer, or prevent certain types of tumors, such as those evolving through the p53 pathway, from developing, it gives us clues about how the tumors could be prevented in the future and potentially lead to chemopreventive efforts,” Karagas said.
