MRI is also recommended for women at increased risk
In addition to yearly mammography screening, MRI is recommended for women at a high lifetime risk (20-25% or greater) beginning at age 30, not 45.
Those who are not at a high lifetime risk should discuss this with their doctor. MRI is typically much more expensive, but your insurance company will likely cover at least some portion if you are proven to be at high risk of breast cancer development.
Take note that MRI is NOT meant to replace mammography screening, but rather supplement it.
