Hi @louwardy. Welcome to the forum, we hope you find it a helpful and supportive place.
I am sorry to hear what you’re going through.
I thought this thread may be useful from people sharing their experiences with Letrozole: Letrozole & Thereafter? - Going through breast cancer treatment / Hormone therapy - Breast Cancer Now forum
If you have any questions in the meantime, you can also speak to one of our nurses, reach them on our free helpline 0808 800 6000.
I truly hope you are able to get some answers soon from members of our community.
Best wishes,
Chloe
