the use of mammography has plunged since a medical working group made controversial recommendations that women in their forties, they may not need to get breast cancer projections, each year one of the three studies on small scale which will be presented Monday.
Studies related to this subject will be presented at the annual meeting of the American Roentgen Ray Society. They do not appear in journals.
Studies suggest that less than doctors recommend annual mammograms for women in quarantine their, fewer patients in this age group are get planned and that routine mammography tumors are more likely to be detected in the early stages of cancer.
The studies examined the impact of the controversial guidelines issued by the U.S. Preventive Services Task Force, a Federal Advisory Board.
Who decides on mammograms? Inside of the task force
In November 2009, the group said that annual mammograms should not be automatic at the age of 40 years and that doctors should discuss their risks and benefits with their patients. He recommended that projections of routine mammography every two years to the ages of 50 and 74 women.
"The advantage among women 40 to 49 years is small enough, said Dr. Virginia Moyer, President of the task force, on the annual mammograms." There is a real, but rather modest advantage. There are also risks, and they are higher in women younger than older women.
Mammograms are less efficient to detect growths in young women, whose breasts are perhaps more dense. Screening improves with older women, because breast tissue change over time.
As a result, some women experience false positive, anxiety and unnecessary biopsies by mammography, according to the data. About 15% of women in their forties, their detect cancer of the breast by mammography.
I should get a mammogram?
"The benefit is modest enough, it must be an individual decision," Moyer said about mammography for women, in the quarantine their. "."
This Council contradicted cancer groups such as the American Cancer Society and Susan g. Komen, who said women 40 to find a cure, and beaver to get checked every year. It sparked an immediate outcry from these groups and cancer survivors, who say mammograms of younger women routine that 50 can save lives.
Breast cancer rates U.S. ounce-dropping now stable
Suspicious vintage captured in regular screening mammography is more likely to be in the early stages and therefore more treatable, said Dr. Donna Plecha, head of the division of mammography in the hospitals of the University Medical Center of cases in Ohio.
Reviewing records of 524 biopsies (samples of suspicious growths in the breasts) by women in their forties, their in 2008-2009 to his hospital.
359 Biopsies of patients in screening mammography, 15% had cancer. These cancers were more manageable because they were captured in the previous steps, said Plecha.
Although 85% of these biopsies is found to be carrying some "can show us that the patient is at higher risk of breast cancer," she said.
"I have not met many patients who do not appreciate us be thorough, to try to find cancers at an early stage," said Plecha. "I recommend always from the age of 40 years, the screening mammography" because captured cancers earlier would be more curable.
ID of breast cancer would be more precisely by docs who see analyses more
The Plecha findings were not surprising of Moyer. It is clear that the annual projections would include cancers before they progress, she said.
The study assumes that catch the first steps for women 40-49 years would result in fewer breast cancer deaths.
"The data we have suggest that 1 mile will benefit from mammography in the age of 40-49," she said. "There are many set of assumptions that are not supported by the data, that they presented".
The Working Group did not say do not get mammograms, said Moyer.
"It might make women want to get the test", she said. "This is a decision that should belong to the woman with appropriate share info."
In another study, Dr. Lara Hardesty, head of the section of the breast imaging at the University of Colorado hospital, examined the results of the investigation of less than 50 internists, gynecologists, family physicians and nurse-midwives.
She found that clinicians less were recommending mammograms annual after working group guidelines have been issued.
Before the guidelines, 56% recommended mammograms for women in the range of 40 to 49 years. After the guidelines, this rate has decreased by 20% and 56% of clinicians reported that they discussed the risks and benefits of screening to patients. This decline, Hardesty said, "is a statistically significant difference", but it also showed that more doctors were discussing mammograms with patients.
Also, Hardesty concluded that there is 205 mammograms less among women in their forties, their after the guidelines were issued. In patients 50 and older, mammograms increased slightly 4,479 patients to the inhabitants.
It was not known why mammograms in 40s decreased as mammograms of older women increased slightly.
Hardesty offered this hypothesis: older women are used to have annual mammograms because they have for years. During this time, younger women may feel as if they do not get this screening.
Although the Working Group concluded that the net benefit of mammography in quarantine is small, Hardesty said: "If you are the only person find us your cancer, it is the world to you".
