Breast cancer rates have halved along with discontinuation of hormone replacement therapy, according to a study published online in the Journal of the National Cancer Institute. The study was published in The Telegraph in the UK.
The Telegraph said:
“Dr. Prithwish De of the Canadian Cancer Society and his colleagues found that HRT use increased from 12.7% in 2002 to 4.9% in 2004.
During the same period, breast cancer rates fell 9.6%, even though the same number of women had mammography tests.
Between 2004 and 2006, HRT use remained stable at around 5% of women aged 50 to 59, but breast cancer rates started to rise again.
Dr De wrote: “ The results confirm the hypothetical link between the use of hormone replacement therapy and the incidence of invasive breast cancer and indicate that the sharp decline in the incidence of breast cancer in 2002 was probably explained by the concomitant decline in the use of hormone replacement therapy in Canadian women. ”
The study’s authors said these numbers support existing evidence for the link between HRT and breast cancer.
