CT scan on
kids triples risk of developing cancer
NEW DELHI:
Children subjected to CT scans with high radiation doses face a three time
increased risk of suffering from leukaemia and brain cancer
during their lifetime.
In the most conclusive evidence till date, a study published in British medical journal Lancet on Wednesday says radiation exposure received from two to three CT scans of the head in childhood (aged under 15 years) — giving a cumulative dose of around 60 milli-Grays (mGy) can triple the risk of later developing brain cancer.
In the most conclusive evidence till date, a study published in British medical journal Lancet on Wednesday says radiation exposure received from two to three CT scans of the head in childhood (aged under 15 years) — giving a cumulative dose of around 60 milli-Grays (mGy) can triple the risk of later developing brain cancer.
On the other hand, around 5 to 10 such scans (cumulative dose around 50 mGy) could triple the risk of developing leukemia.
The authors from the Newcastle University studied around 180,000 patients who underwent a CT scan between 1985 and 2002 from 70% of the UK's hospitals.
These data were then linked to cancer incidence and mortality reports in the UK National Health Service Registry between 1985 and 2008.
From this, they calculated excess incidence of leukemia and brain tumours. The dose of radiation received by the brain and bone marrow varied by age and body part scanned. A total of 74 from 178,604 patients were diagnosed with leukemia and 135 of 176,587 were diagnosed with brain cancer.
The authors say that, of every 10,000 people between the ages of 0-20 years receiving 10 mGy from a CT scan, there would be about one expected excess leukemia case, whereas there were would be one excess case of brain cancer for every 30,000 people. Applying the dose estimates for one head CT scan before the age of 10 years, this would translate into approximately one excess case of leukaemia and one excess brain tumour per 10,000 patients in the decade after the first exposure.

Satyamev
Jayate: Aamir Khan refuses to apologize to doctors, ready to face legal action
Bollywood superstar Aamir Khan today refused to apologize to
the Indian Medical Association which has accused him of defaming the medical
profession through his popular TV show Satyamev Jayate and said he is ready to
face any legal action threatened by it.
"I am very comfortable if they
(IMA) plan to take legal action if they feel that I have done something wrong.
Of course, the courts are available for them. My answer is no, I will not be
apologizing," Aamir told to a news channel.
The actor denied IMA's charge of
defaming and insulting the medical profession.
"I deny that I have done that.
I have the highest respect and regard for the medical profession," he
said.
In an episode, aired on May 27, the
47-year-old actor highlighted the malpractices in the medical profession.
The IMA
had demanded an immediate apology from Aamir and warned him of legal action if
he failed to do so. "Aamir Khan should apologise for having defamed and
given one side of the story on medical profession. If he does not we are
contemplating to take legal action against him for defaming and demoralising
the medical profession in his TV show," IMA secretary general Dr D R Rai
had said.
Aamir, who has been focusing on
social evils through the show, said his show is not against doctors or the
medical profession.
"If the medical profession has
been insulted and defamed by anybody, it is probably by those who are indulging
in unethical practises," Aamir said.
