I am coming up to 74 years of age , Ive had a lump removed and had radio therapy for 3 weeks and have been taking Letrozole for 5 months . I am very active and like to garden too . Since taking Letrozole the pains in my leg muscles and right inside my bones ( well thats what it feels like ) and have been  so painful that I have had to get up in the night to take pain killers , its not so bad in the day but at night its a different story . However gardening is very painful . I had 2 oncology telephone appointments but felt I was getting nowhere so I wrote a letter to the chief oncologist ( the lady I first saw before lockdown ) , she phoned me at home and was really helpful , she mentioned other drugs but i dont want to take them as my friend takes them and now has insomnia and anyway I am grateful I dont have the side effects I dreaded ,like mood swings , fatigue , depression etc . The oncologist said to me stop taking them for a month and see how you go and I'm sure but not positive she hinted that the protection the letrozole gives isnt a high percentage . I felt like I had been given a " get out of jail card " as I really dont want to take these horrible tablets . I am now weighing up in my mind do I ask if i can  stop them and thereby protect my bones and quality of life ,but I dont want to go against the doctor and will they blame me if the cancer comes back ? Though I dont see how they can blame me as the letrozole doesnt give 100% protection . I dont know how long I am going to live and I dont want to end up a very old lady who falls and breaks her hip because she has weak bones, the  quality of life is precious to me. Its a gamble anyway as you may never have the cancer come back ,and what if they say in 5 years " Oh we been researching and Letrozole is only needed for a few months " after all they are now saying you only need one week of radio therapy . its a dilema .. I really dont want my bones ruined .
