Thanks ! I have a feeling they forgot to prescribe it after a meeting and I’ve been chasing it up for about 4 weeks ! Picking it up today!

Hi bella68

Thank you for posting and asking when the optimum time is to start letrozole.

Hormone therapy is usually started 4-6 weeks after surgery although as @klf says, when you begin depends on the preference of your oncologist. Some oncologists will prescribe hormone therapy to start alongside your radiotherapy and others recommend you start after radiotherapy has finished. Research suggests that there is not a significant survival benefit to either approach. It sounds as though you have now received your prescription but if you have any further questions about when to begin taking it, it may help to talk to your breast care nurse or treatment team.
