February 2015 i did biopsy test for breast cancer and it out clean my question is do i have to go for it again in february 2016 if not every when should mammogram or biopsy be done for breast cancer ?

Your physician: should have told you exactly what to do after a negative breast biopsy, presumably for abnormal mammogram or ultrasound. Repeat mammograms are recommended at 6 and 12- month intervals, and if there is definite lesion or change in size, repeat ultrasound and/or biopsy would be warranted at that time. Please make sure you follow your physician's plan closely. Thanks for trusting in HealthTap.
