The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

This paper analysed the scientific data between January 1966 and October 2012 to quantify the association between statin use and risk of bladder cancer. A total of 13 studies contributed to the analysis.

The paper found:
(a) Statin users had a 7% increased risk of bladder cancer compared to non-users.
(b) Long-term statin users had a 21% increased risk of bladder cancer compared to non-users.

The data from the analysis shows that statins users have more bladder cancer than non-users.
