Having too many CT scans is Not good. They expose you to a lot of radiation which in turn can cause cancer to develop later on due to the exposure. I know sometimes people have to have them, but honestly, you only want to have one if you absolutely have to have one. If you can do another route of testing, like MRI or ultrasound, this would be better. I just read an article on people being over-exposed to these scans. They had a list of scans NOT to have if at all possible. This was their list in the exact order of with the first ones being the tests that expose you to A LOT of radiation.
1) CT scan
2) barium enema, or xrays
3) chest xrays
I have had about four to 5 CT scans in my life for different things. I do not want anymore if I can help it. Always be proactive about your health and situation. You have to know that when you visit an ER, they do not look at you like a person, they look at you like just a number, or just another patient. They are not going to do what is always in your best interest. You have to advocate for yourself at times like this and sometimes make the decisions or requests. For example If you ever find yourself in a situation, or you are at the ER and a doctor just randomly says you need a CT scan. Always ask Why he or she thinks this, and also mention your concerns about having to many CT scans. Tell the doctor that you do NOT want to be exposed to any more CT scans unless it is an extreme emergency or in the event that there is No other alternative. Otherwise tell them you would rather have maybe an MRI or a test that does not expose you to needless radiation...
