question: Hi thanks for looking at my question I am 57-year-old male with heart issues in August 2016 and went to the ER because I was unable to breathe turned out I had about 1 3/4 L of fluid around my heart The fluid was blood or had blood in it I m unsure about that fact but my heart doctor was and is very concerned and referred me to a cancer doctor the cancer doctor and family doctor don t really seem to be concerned at all Do I need to be concerned about this and push for more answers or is it just something that happens and doesn t necessarily mean that its serious thanks Brad
