It can be a source of pride—in some families, chins, noses, earlobes—even the way your brothers, sisters, aunts and uncles talk and laugh all seem to pass from generation to generation. But the possibility you might inherit the risk for developing breast or other cancers from your family is something no one wants to consider.
