I have heard HRT causes breast cancer, is this true?

There is a very small increased risk of being diagnosed with breast cancer if you use HRT. The risk is less than being overweight, drinking alcohol or being physically inactive and has not been seen in all research. This risk is mostly seen with old-style HRT and is thought to be even less with modern, body-identical HRT. Women need to balance the risks versus the benefits of using HRT as it applies to them individually. You can read more about HRT and breast cancer in the vault.
