just found out that I am comorbid. Few weeks ago I took a Coronary Artery Calcium Score test & got some morbid (and shocking) results. Now to further test my coronary artery disease I am getting a nuclear stress test. I just wrote to the cardiologist's office as to whether, given my cancer diagnosis, it would be better to get an echocardiogram after reading that the isotope used carries a risk - though very minor - of cancer. Wikipedia says "As the tracers used for this test are carcinogenic, frequent use of these tests carries a small risk of cancer.
Any thoughts on differences in image quality vs. risk based on your knowledge and/or exeperience would be much appreciated.
