Scientists from the Institute of Cancer Research in London conducted a study which proved that women who had been on HRT have 60% higher chances of developing cancer.
This study included 39,000 women from Britain and they were tracked during their menopause. This study is going to reignite a very old debate about the risk and the benefits of Hormone Replacement Therapy (HRT).
It was proven that those women who took combined form of HRT (the therapy contained progesterone and oestrogen) have 2.7 times higher risk of developing breast cancer over a period of time of five years than those women who weren’t receiving this treatment.
According to a big trial from 2002, HRT increased the risk of developing breast cancer and did not reduce heart disease. However, ghostwritten articles which were published shortly after the study downplayed it claiming that there was no general agreement on Prempro’s breast cancer risk.
Menopause usually strikes women in the late 40s and early 50s. It can cause hot flashes, depression, night sweats and headaches. Moreover, it can cause memory loss and bone disease on the long term. A number of women think that “natural” hormones would be safer or better. Nevertheless, the term “natural” can be interpreted in a number of ways.
HRT calm symptoms by replacing progesterone and oestrogen, which are the female hormones that the body stops producing. This raises the risk of developing cancer.
In normal circumstances, 14 out of 1000 women in their 50s are expected to develop breast cancer in a period of time of 5 years.
According to new findings, 34 out of 1000 women are to develop breast cancer if on a combined HRT.
What’s very important is that the risk increases the longer the therapy is taken. Those women who took HRT for 15 or more years have 3.3 times bigger chances of developing breast cancer.
Women today are warned to take the lowest dosage of HRT and to stop taking them as soon as they can. Some women are afraid that the menopause symptoms will return if they stop taking this pills.
However, the researchers proved that once the women stopped taking HRT, the cancer risk returned to normal.
According to Professor Anthony Swerdlow, who is the leader of the study, the research showed that some previous studies have probably underestimated the risk of breast cancer related with HRT. He added that they have discovered that combined HRT clearly increases the risk of developing breast cancer. He adds that their findings provide information which will make it possible for women to make decisions based on information about the possible benefits and risks of the use of HRT. These findings were concluded from a major study which included more than 100,000 women. According to the researchers, previous studies failed to relate HRT with increased risk of breast cancer since their information was not up to date.
Baroness Delyth Morgan, who is chief executive at Breast Cancer Now said that using or not HRT is a personal choice completely and it is crucial that women are aware of the risk it brings. Moreover, some women consider HRT a necessity.
Nevertheless, the good news is that the risk of breast cancer decreases when women stop taking HRT.
According to Dr. Heather Currie, HRT is helpful for menopausal symptoms, especially with hot flashes.
Women must have clear information which is based on evidence about the risks and the benefits of HRT when deciding to start the treatment or not.
