Does the pill cause breast cancer?

There was a recent article in the Guardian entitled - 9 Major Myths about the Pill. A lot of them we have already discussed here but one we have not discussed much at all.

The article says - a study of 1.8 million women shows that the pill increases the risk of breast cancer by 38%

This is true but also misleading - and if you are taking the pill or thinking about taking the pill this is worth knowing.

The risk of breast cancer among women who take the pill is very small - so a 38% increase of something very small is something very small indeed.

The study that they are talking about in the guardian shows -

There was no increase risk of breast cancer among women who had used the pill for less than 5 years.

The age adjusted risk of breast cancer among women who have never used the pill is 55/100,000 person years

The age adjusted risk of breast cancer among women who use the commonest form of combined pill is 72/100,000

A ‘person year’ is when one person uses the pill for one year’

Among every 7960 women who used the pill for a year there was 1 extra case of breast cancer.

Hope this is helpful in putting this article into context - but if you have further questions then do post.

Many thanks
