Another study and nothing will change, because the cancer industry is big business.
Breast cancer rates fell as women turned away from hormone replacement therapy, a study has shown, boosting understanding of how the two are linked.
Use of HRT to combat the effects of the menopause halved in Britain after studies suggested it could increase the risk of breast cancer.
A study conducted in Canada has now found that as use of the treatment dropped, the number of cases of breast cancer detected also reduced.
However after several years breast cancer rates began to increase again which, researchers said, suggests that not using HRT simply led to their tumours growing more slowly.
The hormone, oestrogen, contained in some forms of HRT can fuel certain types of breast cancer.
So the research suggests that the link between breast cancer and HRT is due to the treatment causing tumours to grow more rapidly and so be detected on tests. Whereas when fewer women use HRT, the tumours grow more slowly and so take longer to be detected and show up in official rates.
The findings were published online in Journal of the National Cancer Institute.
