why are my answers important?

The Million Women Study aims to provide information which is relevant to all women. To do this as many women as possible, from all walks of life and from all over the UK need to take part. You may think that because you are very healthy/not using hormone replacement therapy/a lifelong non-smoker etc, your answers are not important. In fact, the opposite is true; the only way the study can obtain reliable information about the factors affecting women’s health is to get information from a whole range of different types of women, with different experiences, lifestyles, diets and family histories.
