Are larger breasted women more likely to develop breast cancer?

It's not clear if women with large breasts have a greater risk. They certainly have more breast tissue in which to develop breast cancer and it can be more difficult to detect a breast cancer in a larger breasted woman because there is more tissue to feel through. In women with large breasts there are some case series which show the breast cancers present at a more advanced stage because of detection difficulties. However, there's no routine recommendation for any different screening for a women with larger breasts than a women with smaller breasts. However, having said that, if a woman has denser breasts and denser breast tissue a mammogram might not pick up breast cancers. Recently the American Cancer Society recommended breast MRI for screening for women at higher risk for breast cancer and this includes women with denser breasts.
