Hormone replacement therapy increases the risk of ovarian cancer, analysis of 52 separate studies has found.
The University of Oxford research, found an extra case for every 1,000 women taking the drugs for five years from the age of 50.
Lead researcher Sir Richard Peto said claims there was no risk for short courses of HRT “simply isn’t true”.
HRT drugs are used to alleviate the symptoms of the menopause, which can be so severe they interfere with day-to-day life.
women take HRT mostly for between two and five years.
There is an increased risk of breast cancer, which has been well documented. However, the drugs have also been found to reduce the risk of osteoporosis and bowel cancers.
But the impact on ovarian cancer has been debated, particularly for those taking the drug for less than five years.
Scientists behind the latest study, which looked at data from 52 separate studies including 21,500 women with ovarian cancer, say it proves there is a link.
Prof Sir Richard Peto specified there would be one extra death for every 1,700 people taking hormone replacement therapy.
He said the risks would be reduced for those taking it for a shorter period of time but were still there.
He added: “If it were me and I had really bad symptoms, I’d worry more about those than any possible risk.”
Theresa Chaffeysaid: “I wasn’t actually given any information in regards to any breast cancer risk or ovarian cancer risk.
“Hearing the news today is very worrying because of actually being on HRT for so long and with GPs continually saying I need to stay on it for my bones as well as any symptoms.
