Hello again Luv,
Lets do some math.
I have consulted several sites and they all seem to agree that the average effective dose for a head and neck angiogram is 5.0 mSv (millisieverts). That is the dose one would get from being exposed to 5.0 milligray of radiation. 5 mSv is slightly less than the dose one would get from living in Denver, Colorado, for six months. Radioactive city, Denver, mostly from Radon gas that leeches out of the ground. Denver also has below-average rates of most cancers, so go figure.
By way of contrast, my radiotherapy to mop up after my surgery involved 66.6 Gray of radiation delivered as 37 1.8 Gray sessions. That means that every day I received 360 times as much radiation as you did. To get 66.6 gray from head and neck angiograms I would have to have an angiogram
every day for 36 1/2 years.
As for your cancer risk, the figure I have seen from the NRC is that each mSv increases one's lifetime risk of cancer by 0.004 percent. So your 5 mSv increases it by 0.02 percent. That's one cancer in 5000 if one believes the NRC... which I don't... I think it's too alarmist... because, Denver.
Here are some websites I looked at for my numbers.

You are mortal so something is going to kill you sometime in the next 80 years or so. But it won't be cancer from your angiogram. So, you are right that you are doomed. We all are. But you are no more doomed than any other 33 year old woman.
Unless you worry yourself to death.
