I am a diabetic & have had high blood sugar levels in the past that have caused high blood pressure. Right now my blood sugar levels are normal but I am getting real bad headaches,is this a signI am having having either high blood pressure or the start of brain cancer? You see cancer does run in my family & my Mother died fom Pancreatic Cancer while Daddy died with a rare form of blood cancer. I worry lots abot getting cancer since both my parents died from cancer but I worry more about the possibility of me having high blood pressure & a possible heart attack. I do not wish to leave my husband a widower so quickly,for I recall my experience in losing my first husband to death and watching him die in front of me I cried & I was in shock. I do not wish this for Richard,so what steps can I do to prevent it? Thanks! C.V. Berndt
