Do all women with small breasts have dense breasts? My mom had dense breasts and had breast cancer at 54. Does this mean I will?

In brief: Yes - No

Most women who have smaller breasts have denser tissue.
That is because breast tissue is composed of fibrous tissue and fatty tissue. The smaller breasts have less fat so the fibrous tissue is more condensed. Just because your mother had breast cancer does not guarantee you will. HOWEVER, you should be monitored closer because you are at a higher risk. See a local breast surgeon for guidance.

In brief: No

Dense breast have nothing to do with size.
It represents a mammographic finding where most tissue seen on the film is breast tissue with little fat present. With age more fat replaces the existing breast tissue so that mammograms can be more easily interpreted. This is one of the reasons mammos should not be performed before age 35. The other is that younger breast tissue sensitive to RT.
