I was looking at CT Scans and found a few articles implying that CT scans cause cancer. One article quoted numbers of 1-2% of cancer deaths per year, caused by a CT scan, or several CT scans.
So.... There goes my plan of a 2 yearly CT scan.
I'd like to read these articles. With something as complex as cancer, it's very hard to pin point a single cause. If I were you, I'd be skeptical at best. But yeah, I'd like to read these parers.
Other factors that should be addressed:
What were the subjects diets like?
What were their fitness levels?
What type of climate did they live in?
Smokers/Non smokers?
Medications?
Alcohol intake?
Existing medical conditions?
