I had a breast tumour removed 5 years ago. I took Tamoxifen for 2 and a half years and Arimidex for the next two and a half years. I had a terrible time on Arimidex but persisted. The side effects were trully terrible. I am due to stop taking the Arimidex. What will the effect on my health, including my weight and my hair be? I had radiotherapy but no chemotherapy...
