There are a lot of posts about how I was shocked when I came to Seongyesa.
One of them is getting a CT scan too easily while receiving a consultation..
That means your body is exposed to radiation.
Nevertheless, in severely ill patients, it is better to get a CT scan to detect the disease.
I'm taking pictures because it's an urgent matter.
I'm just getting plastic surgery consultation.
I saw that CT scans were taken too often.
I was so shocked
Please tell Google, “Getting a CT scan causes cancer.”
Please search at least once and think again.
Especially for minors, if they get a CT scan before they become adults,
The incidence of cancer is 1.5 times higher than that of others.
There are also research results
Radiation exposure is really scary.
I want you to be aware
Looking at the cases of Chernobyl and Japan,
You know it well...
Never take pictures of minors.
If you are an adult and must take a picture,
Ask the hospital in advance if they can burn a CD of the CT results.
So, take the results yourself and go to another hospital.
Dude+++
It's ridiculous that some people treat it like spreading inaccurate rumors.
I am Dong-A Ilbo, Maeil Business Newspaper, Chosun Ilbo, KBS, Seoul Shinmun
A wide variety of media
I scraped up all the articles haha.
I left it in the comment section and moved it to the main text.
I hope you at least take a look! For yourself, not for anyone else!
There are some people who often take pictures during consultations.
There is no harm in being careful, but why bother saying it is okay?
I'm more suspicious of people pushing it away as if it's strange, right?^^
I'll just add a summary! How can you believe a newspaper article?
I have nothing more to say^^

During 2007, radiation exposure from CT scans caused 29,000 cases of cancer and 15,000 cases. The research results showing that the American died were published in the December issue of the Archives of Internal Medicine.
The research team stated that there was evidence that Americans are overexposed to radiation for diagnostic tests and that CT scans in particular have a significant impact.
CT scans are performed by doctors to view the inside of a patient's body, and are exposed to much higher radiation than conventional X-rays. For example, it is known that a chest CT scan has 100 times more radiation exposure than a chest X-ray. The U.S. National Cancer Institute has developed a computer program to estimate the impact of CT scans. According to this program, there were approximately 70 million CT scans in 2007, and it was estimated that 29,000 of these were the cause of cancer.

A joint research team from Taiwan's Taipei Medical University and Zhang Huo Christian Hospital found that children and adolescents under 18 years of age are at risk for brain tumors if they undergo CT scans more than 4 times before becoming adults. It was revealed that the likelihood of developing leukemia and lymphoma is more than twice that of children who do not develop leukemia. The results of this study were published on April 24 in the Canadian Medical Journal, an international medical journal published by the Canadian Medical Association.

Recently, a study was published in the medical journal Nature Medicine that analyzed the impact of exposure to radiation from CT on the occurrence of blood cancer. The study followed a total of 948,174 people around the world who underwent CT scans before the age of 22 and examined how many of them developed blood cancers such as leukemia and lymphoma.
As a result of the study, when exposed to radiation through CT scanning, the incidence of blood cancer increased by an additional 1.96 times per 100 milligray (mGy). Milligray is a unit that indicates the level of radiation exposure. When a CT scan of the abdomen is performed once, the patient is exposed to approximately 5 to 20 milligrays. The incidence of blood cancer increased as exposure to radiation increased. The incidence of blood cancer was not high below 10mGy, but it was 1.40 times higher when exposed to 10-25mGy. When exposed to more than 50mGy, it increased 2.66 times.
Because cell division constantly occurs within the bone marrow for growth in children and young adults, excessive exposure to radiation causes cell division abnormalities, increasing the risk of blood cancer. These days, many teenagers also undergo CT scans when they have back pain or abdominal pain, but it is best to perform CT scans only when absolutely necessary and avoid repeated tests.

When looking at each type of cancer, people who had a CT scan had the most common blood cancer (376 people), followed by thyroid cancer (273 people) and brain cancer (166 people). appeared.
In general, it is known that cancer in children and adolescents is very rare, so it is difficult to confirm such differences. Big data has made this possible. In fact, this study is the largest ever big data study among existing medical radiation exposure-related data, and is also the first to confirm the impact of CT scans on cancer occurrence in Asians.
Hong Jae-young, a professor of orthopedics at Korea University Ansan Hospital who led this study, said, “CT scans are like a double-edged sword. Medical tests using radiation first provide many advantages, enabling accurate diagnosis and treatment when a disease is suspected. After assuming that “it definitely helps your health,” he said, “However, as the risk of cancer in children and adolescents due to exposure to CT radiation has been confirmed, medical staff need to be more careful when performing CT scans on these children.” He said.
In addition, Professor Hong emphasized that “Asymptomatic children and adolescents should definitely avoid receiving CT scans for health checkups,” and added, “If a disease is suspected and a CT scan is required, There is no need to hesitate about the test, but if there is an alternative ultrasound or MRI test, there is a need to consider minimizing radiation exposure,” he said.

According to overseas studies, for every 100 mSv of medical radiation exposed, the risk of developing cancer within 50 years increases by 0.5 percentage points. Although the impact of low-dose radiation of 10 mSv has not been clearly revealed, academic circles estimate that it increases the cancer incidence rate by 0.05 percentage points based on previous studies. Considering that the lifetime cancer incidence rate for Koreans is about 30% on average, it is calculated that the cancer incidence rate for a person who receives 100 radiation tests of 10 mSv each time increases to 35%.
The younger the age group under 40, the more caution is required. It is advisable to undergo radiation testing only if you have a family member with cancer or are confirmed to have a gene that makes you vulnerable to cancer. Kang Geon-wook, a professor of nuclear medicine at Seoul National University Hospital, said, “It may be safer for young people to reduce the number of radiation tests as much as possible and choose other tests such as magnetic resonance imaging (MRI) or ultrasound.”

Excessive exposure to radiation damages DNA and increases the incidence of cancer. Therefore, if a CT scan is inevitably required for diagnosis or treatment, it is advisable to inform the medical staff of the number of recent CT scans and replace it with an MRI without radiation exposure or an X-ray with a low radiation dose. According to international research results, cancer caused by CT radiation accounts for 1.5 to 2% of all cancer patients. According to this calculation method, 4,803 cancer patients occur annually in Korea due to CT radiation. For this reason, the World Health Organization (WHO) classifies CT radiation as a class 1 carcinogen. The occurrence of cancer is caused by a complex effect of genetics, family history, wrong diet and lifestyle habits, etc., but we cannot rule out the possibility that excessive exposure to radiation from frequent CT scans hastened the onset. There is nothing.

Is CT scan taken during health check-up really safe?
Diagnostic medical radiation exposure is by no means negligible. According to a study conducted in the UK, it is estimated that at least 15% of the total radiation exposure of the British public is due to diagnostic medical radiation.
Research has recently been conducted to estimate the health effects of this. Some of the research results are as follows. A 2004 British study estimated that diagnostic radiation was responsible for 0.6% of all cancers that occurred in the UK over the course of a year. In 2007, it was estimated that 29,000 additional cases of cancer would occur in the future due to the number of CT scans performed in the United States, of which 6% were breast cancer and the rest were breast cancer. It was expected that lung cancer and brain cancer would occur. It was estimated that 1 in 270 women in their 40s who underwent CT coronary angiography would develop cancer as a result. There is also a study that estimated that 1 brain cancer will occur in every 11.080 male head CT scans. In the UK, based on these research results, the radiation dose from radiological examinations performed in the UK was estimated to be approximately 800 men and 1,300 women per year. It was assumed that cancer occurred purely due to radiation tests. These are people who would not have developed cancer if they had not undergone radiation testing.

Excessive radiation from the Positron Emission Computerized Diagnostic Imaging (PET-CT) device, which is used by some university hospitals for expensive health checkups for early detection of cancer. It was revealed that the risk of exposure had been reduced. On the 24th, the Board of Audit and Inspection conducted a survey on the 'Radiation Safety Management Status' conducted by the Nuclear Safety and Security Commission and the Ministry of Health and Welfare in September and October of last year. According to the results, 10 medical institutions, including the National Health Insurance Corporation and University Hospital A, did not inform anyone of the fact that the amount of radiation exposure was high while distributing PET-CT consent forms, notices, and precautions.

"I am frustrated with the medical reality where they start with a CT scan without even looking at the condition"
A current professor of radiology expressed his frustration with the reality that CT tests are being overused. This is because the problem of radiation exposure cannot be ignored.
Professor Seong Deuk-je of the Department of Radiology at Korea University Anam Hospital presented on the latest knowledge of CT in the field of urology at the fall conference of the Korean Urology Association on the 24th and discussed real-world problems.
Professor Seong said, “Residents prescribe CT first,” and “They are so dependent on CT that they perform a CT scan and then evaluate the patient’s condition. He pointed out, “It’s a frustrating reality.”
He continued, "If CT scans are taken multiple times, the amount of radiation exposure increases. “It accumulates rather than being discharged out of the body,” he said, emphasizing that “we need to reduce the number and scope of CT scans and consider once again making CT scans every three or six months as a habit.”
According to Professor Seong, one abdominal CT scan is equivalent to receiving 4 to 5 years of natural radiation, and a head CT is equivalent to receiving 1 year of natural radiation in one go. .

Director Lee pointed out that radiation exposure during diagnostic processes such as CT scans and plastic tests can and should be controlled. According to 2005 data from the Korea Institute of Nuclear Safety, head CT is 2m㏜, chest CT is 8m㏜, and abdomen and pelvis CT is 10m㏜. The amount of radiation exposure far exceeds the annual radiation exposure limit of 1m㏜. One chest CT scan exposes you to 8 years worth of radiation.
Director Lee pointed out, “Not only are most people unaware of the amount of radiation exposure from CT scanning, but the rate of CT re-screening is also high.” Director Lee pointed out that the frequency of re-photographing within 30 days of moving to a hospital was 19.5% as of 2011, and said, “There are very few cases where the tissue changes rapidly within 30 days, so there is no need to re-photograph. The 20% figure is for the hospital’s profit,” said.
