Breast Cancer Screening
Age < 40 years old
Monthly breast self examination, optional yearly ultrasound of the breasts if breasts are lumpy and self or clinical examination is difficult.
Age 40-49 years old
Monthly breast self examination, yearly mammogram with or without ultrasound. Ultrasound is useful if the breasts are lumpy or if they are dense as the accuracy of mammogram is slightly lower in dense breasts. But ultrasound cannot completely replace mammography.
Age 50 years old and above
Monthly breast self examination. Mammogram with or without ultrasound can be done 2 yearly in the absence of any risk factors such as significant family history, personal history and use of hormone replacement therapy.  If there are risk factors, it would be prudent to continue with yearly checks.
