Several Metals Named as Possible Cancer Causes in New Report

by on

A new study from the International Agency for Research on Cancer cites 20 possible cancer sources several of which include metals. According to the Chicago Tribune, sponsors of the research The National Institute for Occupational Safety and Health, National Institute of Environmental Health Sciences (NIOSH) and the National Cancer Institute named the following metal containing chemicals, oxides and mineral compounds as possible cancer-causing agents:

¢ Lead and lead compounds
¢ Indium phosphide
¢ Cobalt with tungsten carbide
¢ Titanium dioxide
¢ Welding fumes (not a metals compound but nonetheless related to the metals industries)

Though many of these materials are well known to cause cancer (e.g. lead and lead compounds or cobalt 60 a radioactive isotope), this list also includes “possible carcinogens. According to the study, the 20 agents were classified against a range of parameters as follows:

“carcinogenic to humans (Group 1), “probably carcinogenic to humans (Group 2A), “possibly carcinogenic to humans (Group 2B), “not classifiable as to its carcinogenicity to humans (Group 3), or “probably not carcinogenic to humans (Group 4)

According to the study, lead and lead compounds, indium phosphide, and cobalt metal with tungsten carbide all received the 2A designation (probably carcinogenic to humans) with an S rating meaning “sufficient evidence exists to support the claim. Titanium dioxide and welding fumes received a 2B designation (possibly carcinogenic to humans)

These and the other 20 elements were selected for review for two reasons according to Elizabeth Ward of the American Cancer Society, “One is there is more of a hint in most cases that they might be involved with cancer,” and the second is that some of the areas of focus are used throughout industry (are widespread) and there isn’t enough research to make the link to cancer.

The metal that raised a few alarm bells, however, indium phosphide, a composite semiconductor used in flat screen televisions, “might cause lung damage and genetic changes when breathed in, according to the Reuters report. Indium is a metal whose usage has increased in recent years.

    I had a total shoulder replacement in June of 2017 and was diagnosed with Multiple myeloma 6 weeks ago. Had foamy urine in August of 2017 which is one if the signs of this Myeloma. Looking for input on if you think the metals in the shoulder replacement could cause this cancer? Or the stainless steel bit they broke off while doing the surgery and left it in there.

    Maybe cobalt. It was recently featured in a Netflix documentary as having many side effects.

  3. Bev says:

    The stainless left in could cause cancer. That is a nickle coating, declared carcinogen.

    my 9 year old Doberman got cancer in her leg . broke her femur and was pinned and wired when 18 months. pin was removed after healing but wire remained. cancer was same as the kind Terry Fox had. Broke my hart.
