Following an extensive peer review process, the NTP have finalised their monograph assessing the carcinogenic potential of cobalt and a number of organic and inorganic cobalt compounds that release cobalt ions in vivo. The NTP have recommended listing these substances as “reasonably anticipated to be human carcinogens”. This conclusion was reached based on sufficient evidence of increased tumour incidences at several tissue sites (including the lungs) in both rats and mice.
