New breast cancer screening guidance has been made to give women more women in their healthcare decisions, including personal values and preferences of age rather than their own risk.
The guidance, published by the Canadian Task Force on Intelligent Healthcare, encourages women aged 40 to 74 to consider breast cancer screening with their doctors and make a shared decision in terms of being a & # 39; Getting a mammogram based on women's choices.
The guidance is published in the Canadian Medical Association.
The previous guidelines from 2011 were proposed against women aged 40 to 49 with normal mammograms, and people aged 50 to 74 were advised to receive the screening every two years.
The new guidance "is designated for a position of power, which will make the decision in the hands of individual women in terms of what it is giving priority," said the vice chairman of the campaign Act, Ainsley Moore, a family health at McMaster University in Hamilton.
"I think there was a lot of insult about explaining the proposals," she said.
Although mammography can benefit from & # 39; Reducing the risk of breast cancer from breast cancer, the test can also harm harm, she noted.
It is a beautiful habit, which allows women to be unnecessary to women, they are common and can continue to add extra exams and maybe amazing biopsy.
For example, finding that for every 1,000 women aged 40 to 49 that was broadcast over seven years, there were 294 death certificates, resulting in non-essential biopsies; Even in the 70-74 age group, there were 219 false reds and 30 biopsies per 1,000 women shown.
Moore said there is also a danger that overdiagnosis and overcoming, with problems that may arise from radiation, chimney and surgery.
The most recent medical evidence, which is the newly established guidelines, suggests that a narrow margin can be between benefits and harm, and led the campaign to make "co-employed" recommendations based on patient choices. These include:
- Women 40-49: The action campaign is a protest against the screening, but if women want a mammog, she should talk to her healthcare provider the problems and the potential benefits be connected to the & # 39; her age group.
- Higher risk is risk at risk from those in their 40s from false verification, overdiagnosis and oversight, compared to other age groups. But the least benefit: only one breast cancer is prevented for every 1,700 women with mammography, compared to one death for every 645 women aged 70 to 74 who can scratch.
- Women 50-74: The executive recommends that women in this area get old mammograms every two or three years. This advice is also limited, as some women may be able to; choose not to be investigated if they are concerned about overdiagnosis and harm associated with them.
- There is no screening suggestion for women aged 75 and over, and the guidance does not apply to highly endangered women, such as those with BRCA1 genetic behaviors of BRCA2.
Moore said that diagnosis is a major problem that is related to the nature of the cancers: some are chronic illnesses. become slower, and others are more aggressive and progress faster.
"It is the case that these slow cans, these turtles have been found on screening, but they would not give signs in the life of a woman. They would not be hugs but they would not certainly to kill your death, "she said.
"It is the challenge that doctors can not tell at the time they have found out what the reasons for these cans do and that's not. So that is what they do. to deal with them all … as the non-manipulating effects can also be important.
"And so that's what the women have. These are the factors that doctors have."
Dawn Stacey, senior scientist at the Ottawa Hospital Research Institute, welcomed the woman's change of advice. "I am delighted with this new guide because they now include women's options.
"This is a guide to the guidance so far, so they said that you should do this," she said. "The new guidance that comes out says that this is a recommendation we would, but we have to discuss this with women in all age groups."
So if a mammogram is important for a woman in the 40s, Stacey said, "that's okay."
