Breast & Pancreatic Cancer Risk Reduction. Should I do anything different with my life?

You have answered my question about there is a definate connection between breast and pancreatic cancer. Both my sister and I have had the BRCA test done and we do not have the gene. The genictic people are still very concerned about all the cancer in our dad's side of family. His one sister died at age 31 and the other got breast cancer at 56 and she is now in her 70's and doing great. My mom took the drug DES while pregnant with me. We feel this is what gave her breast cancer. I was told that because she took this drug that I now have a great risk of getting breast and vaginal cancer along with my dad's pancreatic cancer. I don't go the the GYN very often due to the fact that I had an unnesessary hysterectomy 19 yrs age.I am 18 months late for my managram but will be going this coming week. Should I do anything different with my life? My mom got her cancer at age 57 and died at age 71. My dad died at age 69. Dad 12/27/95 and mom 12/22/05. Thanks for your help
