Breast Cancer Screening Guidelines of the Americal Cancer Society
- Women should have an annual mammography and clinical breast examination from the age of 40 years. This should continue till women maintain good health
- Women between the ages of 20-39 should have a clinical breast examination every one to three years.
- Breast self examination has not been proven to reduce breast cancer mortality but should be encouraged as it makes the women aware about the shape and feel of their breasts
- Women at high risk should have an annual MRI in addition to mammography. Women at moderate risk for breast cancer may add MRI to mammography. MRI need not be performed for individuals with a risk less than 15%. MRI is more sensitive than a mammogram and picks up more false positives than a mammogram. It can not replace a mammogram because the mammogram picks up some lesions not picked up by MRI. High risk women are those women who have a more than 20% lifetime risk of breast cancer and women at moderate risk are those with a 15-20% lifetime risk of breast cancer.
