The US Preventative Task Force says something different
The US Preventative Task Force (USPTF) has slightly different suggestions. They say that regular every other year mammography should be done for women ages 50 to 75. The decision to start screening before the age of 50 should be done on an individual basis. Like the other organizations they believe that this decision should be made between the provider and patient and based on a discussion of the benefits and harms.
