Hi @saleha59. I'm sorry to hear about your experience with the nuclear stress test. While you are being injected with a nuclear tracer and radiation exposure can be linked to cancer, the research shows that it takes prolonged/repeated exposure or higher doses of exposure than are used in a nuclear stress test.

Everyone does react to medications and procedures differently, but typically exposure to others is not a side effect and drinking plenty of fluids flushes out any small radiation and the tracer itself with 24 hours. Each provider may instruct you to proceed differently following the procedure.

Many of the unfortunate side effects you experienced are listed as possible side effects, https://www.mayoclinic.org/tests-procedures/nuclear-stress-test/about/pac-20385231.

@saleha59, despite your bad experience with the test, were you able to learn anything through the results of your test?
