Breast pain during hot flush


Re: Breast pain during hot flush

Hello CornwallKaren

Thanks for posting.

Hot flushes are a common side effect of letrozole as you say. Although much less common, some people can experience breast pain when taking letrozole.  However, it's difficult to say why you experience breast pain at the same time as a hot flush, but it could be fluctuating hormones as you mention. It's good to see you reported this to your surgeon, and they have reassured you it is normal.

You may want to connect with other women to see their experience of hot flushes. You can do so through this section of our Forum. Details of all our services are here.

Breast pain during hot flush

I was diagnosed with BC last year, had surgery and radiotherapy and am on Letrazole. Like many people one of the side effects of the letrazole is hot flushes and sometimes during a hot flush I experience pain in my breast at the same time. I had my first annual check up today and I mentioned it to my surgeon who said it was perfectly normal. Stupidly, although I’m happy it’s normal, I didn’t ask why. Can you tell me why I would experience a hot flush and breast pain at the same time, is it hormonal because of the letrazole? Many thanks……
