Question 1

child had two head ct scans at 3 months and 6 months. she had a couple simple x-rays with both. i was unaware this was dangerous. how?

Accepted Answer

Radiation: A head CT scan administers a high dose of radiation so if there is an alternative solution such as a MRI that would be better. Discuss this with your doctor. This is particularly important if she requires further imaging.

Question 2

had two head ct scans in er. one with contrast, one without. both scans done within two hours of each other. will i get ct scan induced cancer later in life. are the risk negligible at my age?

Accepted Answer

: Not going to develop cancer because of CT. Can’t really predict the future but highly unlikely you will develop cancer because of a CT. Risks are low.

Question 3

would 2 head ct scans within only two or three months of each other at my age i'm 17 cause brain cancer and how long would it take to develop?

Accepted Answer

Do not worry: While there is radiation exposure with CT scans, two head CTs are not going to give you brain cancer. You can do more for your health by refraining from tobacco and alcohol than worrying about these CTs.

Question 4

if you had 30 xrays from injury and 2 head ct scans is cancer in your future?

Accepted Answer

Possibly: Radiation damage of tissue does occur.  The younger the person the more frequent there will be a problem. 30 x rays are a large number and certain tissues are more effected than others.  In the neck, thyroid tumors are frequently induced in younger people as a result of RT.  Minimize any further X rays using MRI if necessary and have physical yearly to check that no growth develops.

Question 5

29 year old female 2 head ct scans without contrast within 2 months of one another.  what is my cancer risk?  i have read "small" or "negligible"

Accepted Answer

Negligible: Two CT scans will not raise your risk to a measurable level, above your background risk.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex.

Question 6

are ct scans really bad? my son had 2 head ct scans 6 months apart when he was 3 in the er. they said total msv for both scans was 3.8 msv. i worry about his cancer risk now. is it greatly increased?

Accepted Answer

: We are all exposed to natural radiation. The average person receives a dose of about 3 mSv per year from natural radiation, which includes cosmic radiation from space. These natural "background doses" vary according to where you live. Simply put, the amount of radiation from a head CT is about the same as 8 months of natural background radiation that we are exposed to as part of our daily living.

Question 7

child had 2 head ct scans as an infant, now is a healthy 6 year old. should we be concerned about increased risk of childhood cancer or lifetime risk?

Accepted Answer

Yes.: A slight increase in life time risk.
Much lower than a whole abdomen ct.

Question 8

had 2 head ct scans in 2 years. does this increase my future brain cancer risk even more since they were done so close together?

Accepted Answer

No, I don't think: it increase your brain cancer risk at all. Althogh there is more radiation in a CT than a conventional xray, the risk of cancer inducement is very,very small. I don't think you have anything to worry about.

Question 9

i had 2 head ct scans in 3 months and 4 x rays. one for suspected stroke (negative) and one for concussion. i am 28 year old female?
scan cancer risk?

Accepted Answer

Exposure : You should discuss radiation exposure with any doctor ordering CT, X-ray, nuclear medicine or other radiation exposure tests. There is a cumulative effect and these tests should be done only when the need for the information justifies the exposure.

Question 10

i have had two head/brain ct scans, can that cause brain tumor?

Accepted Answer

highly unlikely: It is highly unlikely that the amount of radiation that you were exposed to during 2 ct scans will have any harmful effect at all.
