The importance of enabling informed decision making for women considering breast cancer screening

Approche qualitative des motifs à accepter ou à refuser la réalisation d’une mammographie : l’apport de la théorie du renversement

Objectif : Examiner les motifs conduisant les femmes à accepter ou à refuser la réalisation d’une mammographie et la manière dont ceux-ci s’organisent autour des états motivationnels de la théorie du renversement.

Méthode : Seize entretiens semi-directifs ont été réalisés. Des analyses lexicométriques et de contenu ont été effectuées en prenant appui sur les dix états motivationnels de la théorie du renversement.

Résultats : Consentir à réaliser une mammographie peut répondre à la volonté d’atteindre un objectif et/ou de suivre les règles communément admises à l’égard de cet examen. Refuser de réaliser une mammographie peut être influencé par la volonté d’atteindre un objectif, par un besoin de liberté, par des préoccupations personnelles et/ou par une aspiration à être au centre du soin. Ainsi, respectivement, les motifs facilitateurs les plus impliqués se rapportent aux états motivationnels télique et conformisme. Les motifs barrières les plus impliqués se rapportent aux états télique, négativiste, intra-autique (et plus modérément à l’état autocentrique).

Conclusion : Les résultats de cette étude, et plus particulièrement le rapport qu’entretiennent les femmes avec les normes établies en matière de dépistage du cancer du sein, peuvent amorcer de nouvelles réflexions dans le champ de la santé publique.

Online information about risks and benefits of screening mammography in 10 European countries: An observational Web sites analysis

Most publications about breast cancer do not provide accurate and comprehensive information, giving few or no data about risk/benefit ratios. We conducted a comparative study among 10 European countries about health information on breast cancer screening, assessing the first 10 Web sites addressing the general public that appeared following an Internet search.With the help of medical residents involved in the EuroNet MRPH Association, we analyzed the first 30 results of an Internet search in 10 European countries to determine the first 10 sites that offered screening mammography. We searched for the following information: source of information, general information on mammography and breast cancer screening, potential harms and risks (false positives, false positives after biopsy, false negatives, interval cancer, overdiagnosis, lead-time bias, and radiation exposure), and potential benefits (reduced mortality and increased survival).The United Kingdom provided the most information: 39 of all 70 possible identified risks (56%) were reported on its sites. Five nations presented over 35% of the possible information (United Kingdom, Spain, France, Ireland, and Italy); the others were under 30% (Portugal, Poland, Slovenia, Netherlands, and Croatia). Regarding the benefits, sites offering the most complete information were those in France (95%) and Poland (90%).Our results suggest that, despite consensus in the scientific community about providing better information to citizens, further efforts are needed to improve information about breast cancer screening. That conclusion also applies to countries showing better results. We believe that there should be greater coordination in this regard throughout Europe.

Breast cancer mortality and associated factors in São Paulo State, Brazil: an ecological analysis

OBJECTIVE

Identify the factors associated with the age-standardised breast cancer mortality rate in the municipalities of State of São Paulo (SSP), Brazil, in the period from 2006 to 2012.

DESIGN

Ecological study of the breast cancer mortality rate standardised by age, as the dependent variable, having each of the 645 municipalities in the SSP as the unit of analysis.

SETTINGS

The female resident population aged 15 years or older, by age group and municipality, in 2009 (mid-term), obtained from public dataset (Informatics Department of the Unified Health System).

PARTICIPANTS

Women 15 years or older who died of breast cancer in the SSP were selected for the calculation of the breast cancer mortality rate, according to the municipality and age group, from 2006 to 2012.

MAIN OUTCOME MEASURES

Mortality rates for each municipality calculated by the direct standardisation method, using the age structure of the population of SSP in 2009 as the standard.

RESULTS

In the final linear regression model, breast cancer mortality, in the municipal level, was directly associated with rates of nulliparity (p<0.0001), mammography (p<0.0001) and private healthcare (p=0.006).

CONCLUSIONS

The findings that mammography ratio was associated, in the municipal level, with increased mortality add to the evidence of a probable overestimation of benefits and underestimation of risks associated with this form of screening. The same paradoxical trend of increased mortality with screening was found in recent individual-level studies, indicating the need to expand informed choice for patients, primary prevention actions and individualised screening. Additional studies should be conducted to explore if there is a causality link in this association.
