Am I at higher risk for cancer now? PLEASE HELP!?

My mom ped away not even four months ago from cancer. I just found out Saturday that my grandpa has less then a month to live because they just found cancer in his pancreas, liver, and spleen. I know that with cancer my mom's oncologist brought up the BRCA2 gene and something like it was rare but my mom had it. Upon researching pancreatic cancer I've found that it too can be caused by this BRCA2 gene. My grandpa that has it is my mom's dad. I'm only 24 I can't deal with this crap. I just lost my mom less then four months ago. Should I be worried about this gene though? Am I more at risk? I tried asking my grandpa's doctor but he said pancreatic cancer is not caused by that gene and that doctors don't ever test for pancreatic cancer. But everything I've found online says that it can be caused by it.
