Mammography: a shared decision | CAROLINE ST-PIERRE



The Canadian Task Force on Preventive Health Care believes that the decision will be shared between women and their physicians based on patient's values ​​and preferences.

This focus on sharing decision is in the heart of an updated guidelines of & nbsp; the group, recorded on Monday.

For women who have no high risk of breast cancer, the study group does not advise women in 40 to 49 years, and recommends mammograms every two to three years for those aged 50 to 74 years. These recommendations, however, are a threat to the relative importance of a woman on the potential benefits and damage of test areas.

While the screen ensures a "decent reduction" in the number of women dying of bone cancer, it also has important disadvantages that women should consider when deciding decisions.

De Dre Guylne Thériault of the Canadian Task Force on Preventive Health Care is aware that the "opposite" may be refusing to test a cancerous potential.

"What we know is that in those cases you find it earlier, there are cancer that have not changed, so who were really" cold "people who would have no (never) symptoms "Patient if she was not written," she says.

The main disadvantage of the screening is "overdiagnosis", which is the renal cancer that has not caused any symptoms or negative effects in the life of a patient. Since the doctors can not determine what cancer will continue to progress and remain stable, diagnostic women treatment is treated – chemotherapy, radiotherapy, surgery – their side effects are serious.

Screening also has a risk of "false positive", resulting in extra test and unreasonable stress for the patient.

De Dre Thériault declares that some women in the 1940s, after they know the benefits and consumers, still decide they want to scratch. And that older people, for whom Mammography is offered, choose not to consider.

"In (new) directive we look for studies evaluated the values ​​and women of women, when they knew the benefits and damage. Four years later, a good majority of women, rather than an individual, decided not to be defended. While in the 50s there was still a good part of the decision to attend, but there were some 39 , they did not decide to scratch. "

The most important thing is, according to the guidelines, to make women make a decision with the support of their doctor, after they are well informed and based on their values.

"If we are concerned, we ask, once we have this data, we decide more is consistent with us," says Dre Theriault.

"And there are things that can be done to reduce the risk of breast cancer, such as regular physical activity, limiting our alcohol business … There are proactive things we can do."
