Arsenic in drinking water
Arsenic is a substance found in rocks and soil that occurs naturally. People can be exposed to many forms of arsenic, and arsenic is broadly grouped into 2 categories:
- organic (meaning that it is combined with carbon)
- inorganic (meaning it is not combined with carbon)
Organic arsenic, such as that found in fish, is considered safe. Inorganic arsenic is not.
Clinical trial discovery improves quality of life
A clinical trial led by the Society’s NCIC Clinical Trials group found that men with prostate cancer who are treated with intermittent courses of hormone therapy live as long as those receiving continuous therapy.
