(Reuters) - A decades-old medical mystery - why antioxidants such as vitamin E and beta carotene seemed to accelerate the growth of early lung tumors in high-risk populations such as smokers, rather than protect them from cancer, as theory suggests - may have been solved, according to research published on Wednesday.
In essence, "antioxidants allow cancer cells to escape cells' own defense system" against tumors,... That lets existing tumors, even those too small to be detected, proliferate uncontrollably.
....
The antioxidants caused a 2.8-fold increase in lung tumors, made the tumors more invasive and aggressive, and caused the mice to die twice as quickly - all compared to mice not given antioxidants.
When the antioxidants were added to human lung tumor cells in lab dishes, they also accelerated cancer growth.
That result jibed with the many studies finding that "antioxidants do not protect against cancer in healthy people and may increase it" or promote it in those who already do, said Bergo.
The significant advance in the study was pinpointing how this can be. What seems to happen is that antioxidants indeed decrease DNA damage, as expected. But the damage becomes so insignificant as to be undetectable by the cell. The cell therefore does not deploy its cancer-defense system, which is based on a protein called p53.
Ordinarily, if the p53 system detects significant DNA damage, such as from ultraviolet light, it kills the cell before it can become malignant. By allowing cancer cells to stay below the radar of p53, antioxidants allow tumors to thrive, the study found.

>>In spite people’s own beliefs that they “feel better” sometimes, <<
“Living” is how you feel, not how many breathes that you take per day. That’s what I call “existing”. If you feel good taking supplements, then do it. If you feel like crap why go on living?
What I recall hearing is about curcumin/turmeric is that they work against cancer cells. That’s why I take them every morning.
I don’t think us old folks are dying off fast enough to keep the Agenda 21 folks happy. We’re interfering with somebody’s plans. Live longer and piss ‘em off. Yeah!
Bull crap again
Have you checked ConsumerReports, or PeoplesPharmacy, to see if your brand is ok, or not - ie, adulterated with unmentionables ?
Thanks I read the abstract. Didn’t notice ANY mention of type of vitamin E
Thanks for posting the link to the study.
Another study about the evils of vitamin supplements from big pharm? I’ll take my chances with vitamins before I’ll risk being killed or maimed by their poisons.
My wife grinds the powder and I fill the capsules.
” My wife grinds the powder and I fill the capsules. “
How IMPRESSIVE ! Thank you. You have given me an idea !
“DiHydrogen Monoxide can be dangerous, even fatal in some cases.”
That’s why John Stossel was trying to get New Yorker’s to sign a petition to ban it, and most of the morons signed.
...or so we are told.
But the people who tell us that lied about global warming, too.
Yes, it’s called the placebo affect and there is always some psychosomatic element to the placebo affect - if told it is the real thing, some on the placebo but not knowing it is the placebo will say they feel better.
I wouldn’t ask you to take something that you don’t feel will improve your health, placebo or otherwise. So you’re safe.
Exactly. Hmmmm . . . . .
