Andreas will give you the definitive answer
about the thallium stress test, but here are
some thoughts to consider.
Thallium is a radioactive chemical. The doctors plan to inject that radioactive substance into your bloodstream. In a very
real sense, you are going to be "nuked."
And then they're going to light up every
one of your cells with their multiple X-rays.
All by themselves, X-rays are dangerous.
Throw in the nuclear thallium, and you have
a very nasty cocktail indeed.
I suggest you do a Search on "The dangers of
Thallium Stress Tests." Do some reading --
and then make up your mind. Listen to your
deep intuition, okay?
I hope you decide to pass on this opportunity
to be nuked. Let's see what Andreas says.
