Is there such a thing as letrozole withdrawal ? I stopped taking letrozole around 3 weeks ago after 7 years, a discussion with my consultant told me I had 0% benefit from taking it. I am now experiencing breast pain in my left breast where I had lobular cancer I had chemo and rads. Anyone experienced this ?
Hi
I can't answer your question but I am a year in to the Letrozole journey and with in weeks of taking it I got pain in my left non cancerous and only breast. I asked the breast nurse and she said the meds thin the tissue and make your breast less dense. So my thinking is maybe it works in reverse and that's what is causing your pain? Good luck with it all x
