Phase:

Phase 3

This was a pilot study to see if it would be possible to carry out a larger trial looking at whether or not selenium can reduce the risk of cancer. This trial was supported by Cancer Research UK.

A study in the USA had shown that a regular small dose of an essential mineral called selenium appeared to reduce the risk of developing cancer by over one third. But the study needed to be repeated to be sure the result was correct.

Researchers wanted to find out if taking extra selenium daily would significantly lower the number of people getting cancer in the general population. The trial began with a pilot study (feasibility study) in the UK. A pilot study is a small study that is carried out to iron out any problems in the design.
