There is now evidence that taking hormone replacement therapy (HRT) long-term increases a woman's risk of breast cancer. But the results of the trials which have been done relate only to women over 50 years. For women (under 50 years), who have had an earlier menopause and are taking HRT, there is nothing to suggest their risk of breast cancer is any greater than women who have not had their menopause.
In the UK breast cancer screening, with 3 yearly breast x-rays (mammograms) is only recommended for women between the ages of 50 and 70 years. This is because there is no clear evidence that it is of benefit in younger women.
As we mentioned, women in their forties, taking HRT, appear to have no greater risk of breast cancer so there are no recommendations for them to have breast screening. Unless you have any factors, such as a family history of breast cancer, which may increase your risk then just being on HRT, doesn’t mean you need regular mammograms.
If you are concerned talk this over with your GP to reassure yourself there are no special reasons for you to have breast screening. It is also important for all women to be aware of how their breasts normally feel at different times of the month (breast awareness) and to see their doctor if they notice anything unusual.
