At what age can you get breast cancer?

Risk increases w age: There is unfortunately no lower age cut off for breast cancer. It can occur in the very young as well as in the mature and elderly. Typically the risk increases with age and screening for breast cancer for women of average risk begins at age 40. In my 23 yrs of practice, my youngest patient was 19 and oldest 92, but I have colleagues who have seen it even younger than that.
