As you know, Dr. Hartmann, the daughters of women who have breast cancer are often worried that they may, in turn, develop the disease. Yes, we are learning so much. Certainly, one case of breast cancer in a family does not make a hereditary syndrome.
Breast cancer is a common disease, so it can happen within a family in that way.
So that tells us there's something going on in this family that conveys a predisposition to breast cancer. It's thought that perhaps ten percent of all breast cancer may be on a hereditary basis. So it's a real proportion, but it's a small proportion. I think the same kind of number is projected for colon cancer.
