High Levels Of Blood HDL Cholesterol Protects Against Heart Disease And Reduces The Risk Of Cancer.
Higher blood levels of HDL cholesterol, the "good" manner that protects against concern disease, are also strongly associated with a tone down gamble of cancer, a new review of studies suggests. "For about a 10-point increase of HDL, there is a reduced peril of cancer by about one third over an average follow-up of 4,5 years," said Dr Richard Karas, official director of the Tufts Medical Center Molecular Cardiology Research Institute and govern author of a report in the June 22 issue of the Journal of the American College of Cardiology neuroblaster - stimulant uk. Those numbers come from an judgement of 24 randomized controlled trials, aimed at determining the impression on heart disease of lowering levels of "bad" LDL cholesterol, through the use of statin drugs.
The upon singled out trials that also recorded the incidence of cancer among the participants. The researchers sign in a 36 percent lower cancer rate for every 10 milligrams per liter (mg/dl) higher stage of HDL effects. But while the relationship between higher HDL and lower cancer chance was independent of other cancer risk factors, such as smoking, obesity and age, Karas was watchful to say the study does not prove cause and effect.
So "We can say that higher levels of HDL are associated with a moderate risk of cancer, but we can't say that one causes the other," he said. Exactly so, said Dr Jennifer Robinson, professor of epidemiology and panacea at the University of Iowa College of Public Health, who wrote an accompanying editorial. High HDL levels may sparely be a marker of the good of good traits that reduce both cardiovascular and cancer risk, she said.
And "People have a lot of characteristics that are all indulgent of interrelated," she said. "They may not exercise, be obese and so on, and so have lower HDL than normal. The higher jeopardize of cancer may have nothing to do with what HDL does".
That's a real possibility, Karas said, but he also mentioned some accomplishable physical mechanisms that might give HDL cholesterol anti-cancer activity. "HDL alters the task of the immune system, which looks for abnormal cells that may be cancerous or precancerous and attacks them," he said. "It also has antioxidant properties, and there is a lot of incite in the role of antioxidants in reducing cancer risk".
HDL cholesterol also has anti-inflammatory activity, which might bill against cancer, Karas said. His laboratory is "starting to think" about experiments to evaluation these various theories, he said. The only convincing proof would be a controlled hard times testing whether medication that raises HDL levels reduces cancer incidence, Robinson said. No such medication is now on the bazaar (other than niacin, which has a minor effect in raising HDL levels), although several are being tested for their sense on heart disease, stroke and other cardiovascular problems. "We actually don't be familiar with that something is causing the disease unless we do controlled trials," she said.
The researchers who show those studies should monitor cancer incidence as well as cardiovascular disease among the participants, Karas said. The unheard of study's finding that an appreciable effect on cancer was evident in just a few years "shows the prestige in current studies to track cancer," he said tablet. "many don't". Until the anti-cancer proposition is proved or disproved, Karas and Robinson said, the best thing to do is adopt the healthy lifestyle that can safeguard HDL cholesterol levels high - exercising regularly, eating a wholesome diet, not smoking and consuming alcohol in moderation.
