How likely is strontium to cause cancer?
The only stable strontium compound that may cause cancer is strontium chromate, but this is due to chromium not strontium. Exposure to high levels of radioactive strontium may cause cancer. Leukemia has been seen in humans exposed to relatively large amounts of radioactive strontium. Leukemia and cancers of the bone, nose, lung, and skin have also been seen in laboratory animals. The International Agency for Research on Cancer (IARC) has determined that radioactive strontium is a human carcinogen.
