There is a gene, brca2. This gene is hereditary and can cause head and neck cancer and breast cancer in women and pancreatic and prostate in men. My cousin has had breast and ovaian cancer, I obviously have oral and my uncle passed away from pancreatic. This same cousin was tested and has this gene and I'm going to get tested too. As it turns out, my cousin has always been interested in the geneology so this is right up her alley. She is doing more research with her doctor. I'll let you know what I learn!!
