i am 62, was diagnosed in 2007 with Stage 1 breast cancer. Following MRI, had bilateral mastectomy and was on tamoxifen for 5 years. Am now on arimidex for past 2 years and cannot get my weight under control. I do not eat starches at all, have restricted my caloric intake and eat vegatables, fruits, protein and yogurt only. I am still gaining and nothing I do seems to work to take the weight off. Any suggestions? Do I need to continue the arimidex?
