Changes in Screening Guidelines Lead to 6% Drop in Mammogram Rates, Study Shows
Mammogram rates in the U.S. have declined by nearly 6% among women in their 40s since screening guidelines were revised in 2009, according to a new study.
"This represents a small but significant decrease," say the Mayo Clinic researchers, because the guideline changes were controversial when they were released.
With the revised guidelines, the U.S. Preventive Services Task Force (USPSTF) called for mammograms to begin for women at average risk at age 50 and occur every two years until age 74. This was a change from its 2002 recommendations, which called for women to have mammograms every one to two years starting at age 40.
Smokers could one day be immunised against nicotine so they gain no pleasure from the habit, according to researchers in the US.
They have devised a vaccine that floods the body with an antibody to assault nicotine entering the body.
A study in mice, published in Science Translational Medicine, showed levels of the chemical in the brain were reduced by 85% after vaccination.
