Do CT scans (computed tomography scans) cause cancer?

There's conflicting literature on whether CT scans can cause cancer. So what's the answer?

Over 10 min video and the answer was “we need more studies “. Lol

Safest approach is to eat healthily, avoid sugar, avoid stress, exercise, avoid alcohol, smoking, and avoid taking unnecessary risks. Once you become ill, there will be unpleasant consequences. This is the remedy for more or less all illnesses. Avoid the hospital as much as possible. If you imagine illness only affects others, you are probably wrong. The health statistics are dreadful and getting mostly worse.

Well it’s been a couple of years since this publication. Where are we at now with the studies?😊

There are some serious issues in the medical field regarding CT scans and X-rays.
1. Doctors and radiologists don't inform their patients about the amount of mSv they recieve for a given CT scan or X-ray on a given body part.
2. There is no law that a doctor or radiologist must inform the patient about the amount of images they plan to take before they begin. Ideally the patient should be shown a table over radiation strenght for each body part and then sign a paper "i accept that i will be given X amount of CT cans or X-rays of a radiation of total radiation approximately 6mSv and i have been informed by my doctor about the healt risks associated with that"
3. The doctor might not have or look at a register showing the amount of CT scans or X-rays the patient has previously had. There should be red flashing flashing color on a doctors moniter if the accumulstive effect of CT scans adds up to a certain mSv value.
4. 1 lumbar spinal X-ray = 15 chest X-rays = 1500 hand or foot x-rays. So it matters what part of your body gets radiation. a patient should be informed about that from the tables of radiation dosages
5. If given injections during a CT scan a patient must see a complete list of all associated sideeffects, and a large scale statistic must be performed.

There must be full transparency when it comes to potential consequences as information or lack thereof can harm a patient. Being nice and telling a patient not to worry does not always help a patient, and it's not honest. To make an educated choice a patient must be given educated information as lack thereof can cause the patient to say yes to later harm, so did the pstient make an error or did the lack of information make the error? The problem with radiation is that it's invisible, so if the patient gets cancer, low bloodcount, memory issues, collagen breakdown, later in life from to many spinal or full body scans (which have the highest radiation dose) does their future development of disease then become part of a statistic attributed to radiation so we get a clear image over the actual effects of radiation, and who could even accurately make and measure such a statistic?

How about the contrast, Gadolinium-based

Why does this video only have 11k views? The whole world should watch this!

So its 2025, whats the update on new research 😭

[pheonix]

I am 19 years old.i had a head CT scan 2-3 weeks ago just for ear pain. From that moment onward i 've been
Feeling random pain inside my head.i am tensed and depressed i cant even focus on my study.when i consulted another doctor he said that CT scan was unnecessary. What
Will i do now ? Is tumor possible in future ??

[saurabhmishra]

I am 22 year old .I got my CT scan done yesterday whole abdomen with contrast .is there harm of ionising X ray radiation .I got to know about this later on after studying .I am really worried plz anyone tell

[GurulivBeran]

Im age of 22 and im really concern that i already had 5 abdomen and pelvis ct scan with and without contrast and one cardiac ablation fluoroscopy... Im really concern that is said im might have above 100 msv.

[Mahdi_Mogan]

Do you think full dental scan is safe(Cone beam computed tomography)?

[YpgheuWeadaz]

Threshold or not. Do u really want to find out by exposing to ct if you can prevent it by doign mri?

[manashidebroy]

I had a brain ct scan in 2018 at 19 years of age. They didnot tell me about the risk of radiation.Every moment I cry to myself, what have I done to myself?....

[laurenclark]

Ive had so many lost count. Plus over 50 dds and oral surgeons. Cant explain why im so sick😢

[isabellamarinilli]

I almost died after my CT scan because my doctors didn’t make sure the radiation level was safe before putting me in the machine

[leohodappsr.]

Do ct scans cause heart attacks? My daughter had a heart attack after receiving a ct scan. And that was before she left the hospital.

Don't listen to music, buy a good sleep mask, and don't take it off until over. Try to fall asleep. Hire a licensed RPN for a shot first. IMO.

[ismailjabane]

CT scan can be investigated by TB gland please reply me dr

[denissutherland]

I had one ct scan was scary because am only 26 and doctors one saying I need contrast then other doctors don’t give me I was so confused so ending up with out contrast everything was ok I think just they could not make this mind up like

[aubrey]

I don't think there is good data about the number of CT scans and x-rays someone gets.
