Women considering hormone replacement therapy (#HRT) can be reassured about the risk of #BreastCancer. New research suggests that HRT is generally linked to only small increased risks. Different types of HRT were linked to different risks of breast cancer.
The researchers looked at data from 99,000 women with #BreastCancer aged between 50 and 79. Each was matched to five other women who did not have breast cancer. This was so researchers could look at the association between taking HRT and having a diagnosis of breast cancer.
The research team found that there was no increase in the risk of breast cancer for HRT taken for less than a year. Risks increased with the duration of HRT treatment and there were also different risks depending on a woman’s age and the type of progestogen taken.
In addition, the risks declined once the HRT was stopped. Five years after stopping, there was no increase in breast cancer risk for women who had taken combined HRT short-term.
