A tumor? In my heart?!?

Paula is a “youngish 60”, as she describes herself, recently retired after a long career in public relations and marketing, and very active. A couple of years ago, for example, Paula and her husband hiked 530 miles together across northern Spain on the famous Camino de Santiago trail. So, definitely “youngish”.

But this past spring, Paula was admitted to the hospital after a week of chest pain, shortness of breath, jaw pain and crushing fatigue. Her initial diagnostic tests suggested she was NOT having a heart attack – but what was discovered after that was something very rare.  .
