Hi. I can’t give you statistics of enertu but over here in uk we have been fighting to have this medication available on NHS but the government and NICE, after numerous nettings with us and hundreds of thousands of people signing a petition, it’s been turned down. But if you go accross the border into Scotland, it’s available in the NHS there!! It’s mainly used for secondary cancers and unfortunately young women here with secondary cancer, won’t survive without it. You are very lucky to have it prescribed for you. Best of Irish ☘️ luck to you. I’m a breast cancer survivor-got my 3 year clear mammogram last May x
