New guidelines for breast cancer screening are meant to give women more of a vote in their health care decisions, to count their personal values and preferences as older and risk factors.
The guidelines, requested Monday of the Canadian Task Force on Preventive Health Care, encourage women in & nbsp; aged 40 to 74 to discuss breast cancer screening with their doctors and make a shared decision about whether a mammogram is based on sharing a woman's presence.
The guidelines are published in the Canadian Medical Association.
The previous guidelines of 2011 are geared toward women from 40 to 49 routine mammograms, while 50 – 74 years are advised to get the screening test every 2 to 3 years.
The new directives are "intended for an empowered position, the decision making in the hands of an individual woman in the height of what they prioritize," said Task Force Vice- chair Ainsley Moore, a family doctor at the McMaster University in Hamilton.
"I think that in the past, many allegations have been interpreted as" the recommendations were interpreted, "she said.
While mammography offers the benefits of getting the risk of death of # 39; To change the breast cancer, the test may also cause a significant dispute, they confiscate.
False positions, women who do not need to be abused, can be abused and can lead to extra testing and possibly leading an invasive biopsy.
For example, the task force found that for every 1000 women from 40 to 49 over a seven-year period, there were 294 false positives, making 43 useful biopsies; Also in the age of 70-74, 219 false positives and 30 biopsies per 1000 women were recorded.
Moore said there was also a risk of overdose and victory, with potential complications of radiometry, chemotherapy and surgery.
The latest medical aspects, based on the updated guidelines, suggests that there might be a narrow margin between benefits and damage, which provides the "power" requirements based on patients' preferences based on patients. They include:
- Women 40-49: The task force advises against the screen, but if a woman wants a mammogram, she will try her health to assess the potential damage and benefits to her age category.
- Those in their 40s see a higher risk of falsification of false positive, surveillance and translation, in comparison to other age groups. But the benefit is smaller: only one breast cancer understands all 1,700 women who have mammography, compared to one death for all 645 women aged 70 to 74.
- Women 50-74: The mission is advised that women in this age group receive mammograms every two to three years. This advice is also intended, as some women do not choose to define when they are important about overtime and associated damage.
- There is no recommendation for pregnancy for women 75 and older, and the guidelines do not apply to high risk such as those who carry a BRCA1 of BRCA2 genetic mutation.
Moore said about the diagnosis is an important issue that relates to the character of the counselor: some slow-growing tumors, while others are more aggressive and reduce progress.
"The problem is that these slow, turtle-growing cancer have been detected on screening, but they would not have symptoms in a lifetime woman, they will not become clear clogs … they will not kill death," she said.
"The challenge is that doctors can not tell you when they are diagnosed which of these cereals will progress and what is not the tendency to treat all … because the effects of non- Treatments can also be important.
"And so are the problems that women are working on.The are the problems that doctors are opposed to."
Dawn Stacey, a senior scholar at the Ottawa Hospital Research Institute, understood the changed advice for women. "I'm curious about this new direction, to prevent the women's present day.
"The guidelines have so far been directors, so she said that this is what you should do," she said. "The new guidelines that come out, say that is what we want to say, but we must have it so that they are in age group with age groups."
So if a mammogram is important for a woman in her 40's, Stacey said, "then it's okay."
