Another New Study Confirms Radiation From CT Scans Linked To Increased Risk Of Cancer
Medical researchers from Taiwan have discovered from a new research that exposure to radiation
from CT scans
is associated with higher risks o
f developing thyroid cance
r and leukemia.
The finds of the study was published today in the medical journal, JNCI Cancer Spectrum
The medical researchers conducted study from a National Health Insurance dataset in Taiwan between 2000 and 2013. The study followed 22,853 thyroid cancer
, 13,040 leukemia
, and 20,157 non-Hodgkin lymphoma
The researchers consulted data from the National Health Insurance program to study demographic and medical information on disease diagnoses, procedures, and drug prescriptions, and the enrollment profiles of all patients. Patients were excluded if they were under 25 years at the time of the cancer
diagnosis, had less than three years of follow-up before cancer
diagnosis, or had a history of a cancer
before the year 2000.
The research results showed that patients who developed thyroid cancer
had significantly higher likelihood of having received CT scans
. In studies that combined patients across age groups, exposure to medical CT scans
was not associated with increased risk for non-Hodgkin lymphoma
However in patients between 36 and 45 years of age, there was a three-fold increased risk of non-Hodgkin lymphoma
associated with CT scans
. In older patients the association between exposure to CT scans
and non-Hodgkin lymphoma
was not evident.
The researchers concluded that patients receiving CT scans
had in general marked increases in the risk of developing thyroid cancer
, especially in female patients and patients younger than 45.
Dr Yu-Hsuan Joni Shao, one of the paper's authors told Thailand Medical
News in a phone interview this morning, "Our study found that CT scans
are associated with an increased risk of thyroid cancer
in adults in all ages and with non-Hodgkin lymphoma
in young adults. The risk is stronger in patients who have higher cumulative doses from multiple scans. The increased numbers of people undergoing CT scans
have become a public health issue."
The findings from this study is extremely disturbing as millions of people globally undergo medical imaging each year and many doctors and even private hospitals deliberately make patient to undergo unnecessary CT scans
merely to increase their billings.
This is not the first study to uncover the correlation between CT Scans
and cancer ,
as there has been a few in the past but most have been suppressed by the medical community or merely downplayed.
Calls to three major medical imaging
companies senior executives for comments about this study was met by refusals to comment.
