LONDON (Reuters) - Nordic scientists pronounced on Wednesday they had found no justification that screening women for breast cancer has any outcome on genocide rates, adding to an already extreme general discuss about slight testing.
In a investigate published in the British Medical Journal, researchers from Denmark and Norway pronounced reductions in breast cancer genocide rates in regions with screening were the same or essentially not as big than in areas where no women were screened.
"Our formula are identical to what has been noticed in alternative countries with nationally orderly programs," pronounced Karsten Jorgensen of the Nordic Cochrane Center in Copenhagen, who led the research. "It is time to subject either screening has delivered the betrothed outcome on breast cancer mortality."
A row blew up in the United States in last Nov after open health officials on the U.S. Preventive Services Task Force questioned the worth of screening mammograms for women underneath 40 and referred to raising the annual screening age to 50.
Cancer doctors and advocacy groups laid open the move, observant the changes would meant some-more women would die from breast cancer. Some lawmakers pronounced they might be used to allotment healthcare.
Breast cancer is the majority usual cancer in women worldwide, accounting for around sixteen percent of all womanlike cancers. It kills around 519,000 people globally each year.
Jorgensen pronounced that nonetheless breast cancer screening programs change by country, Denmark was a great benchmark and his team"s commentary should surprise the debate.
In Denmark, women are screened each dual years from age 50, whilst in the United States mammograms are right away endorsed each one to dual years for women elderly 50 plus, and in Britain the process is for women over 50 to be screened about each 3 years.
Critics of drawn out screening programs contend they can be some-more damaging than beneficial if the additional sanatorium time and costs they require, joined with the highlight and be concerned of fake alarms, are not outweighed by the good of preventing some-more deaths.
In Britain, for example, experts contend around 7,000 women get an nonessential breast cancer diagnosis when screening picks up tumors that would never have caused them any problems.
Jorgensen pronounced his investigate showed this risk-benefit change was not being strike in Denmark, and he speculated the incident would be the same in alternative grown countries.
Evidence right away suggests that for each 2,000 women who are screened over 10 years, usually one stands to have her hold up saved by the mammogram program, he said, since the risk of removing an nonessential breast cancer diagnosis is 10 times that.
"We need to have women wakeful that the possibility they will good from the module is really small," he pronounced in a write interview.
Jorgensen and his group compared annual changes in breast cancer deaths in dual Danish regions with screening programs opposite non-screened regions opposite the rest of Denmark.
In women expected to good from screening (those elderly 55 to 74 years) breast cancer mankind fell by 1 percent a year in screened areas and by 2 percent a year in non-screened areas, the researchers found.
In women as well immature to good from screening (aged 35 to 54 years), breast cancer mankind declined by 5 percent a year in screened areas and by 6 percent a year in non-screened areas during the same period.
