CT scan radiation and protective supplements

Posted by bradzepfan @bradzepfan, Nov 8, 2023

Hello everybody. I believe we are all in the "frequent CT scan" club here so I wanted to share this slide show PDF about reducing DNA damage from CT scans.

I have had the Pure brand and many more. I like it and NOWfoodsbrand.
NOW did an article about the testing they did on Amazon supplements. Google it I don’t have reference- sorry.

Hi Libby,
I believe the article you are referencing is this one:

NOW appears to be a pretty good product. Thanks for your input.

Doctors usually order regular chest CT for us. Will a low does CT like screen cancer work? This low dose CT is only 1/4 of the radiation as regular chest CT.
I have had two CTs this year, and I really really don't like the repeated CT scans. One regular chest CT is equal to 100 X-rays!!! But some doctors are not aware of the long- term cancer risk and order them as many as they want.

"When your doctor orders an occasional x-ray or computed tomography (CT) scan, you probably focus on the findings, not the amount of radiation you'll be exposed to. But if you need numerous tests, you may wonder if you're getting too much radiation exposure and how it might affect you. The concern about radiation exposure is an increased risk for developing cancer later in life. Ionizing radiation from tests such as x-rays or CT scans has the potential to damage tissue in the body, including cell DNA.

"As DNA is damaged, this causes mutations. Some of these are repaired by our cells, but others escape repair. In rare circumstances, these mutations may cause cells to divide rapidly without control," explains Dr. Mark Hammer, a radiologist with Harvard-affiliated Brigham and Women's Hospital. "If cancer were to develop, it could take 10 to 20 years for it to become apparent.""

Thanks Lilianna for this important information! I need to check with my doctor the ones I had is low dose or not. I heard only cancer screening is low dose.
A regular Chest CT is 7 mSv, about 70 X-ray, and a low dose CT is 1.5 7 mSv, about 15 X-rays.

But I do know it has no contrast, at least less damage to kidneys.

About 4 years ago I had a regular CT then treatment and Dr wanted follow up CT. I asked for low dose and he agreed. It does not show as much as regular but he said it would tell him what he needed to know. It was also very fast compared to the regular CT. I much preferred it so worth asking for.
